Description
This production technology belongs to industrial sewage and handles and environmental protection technical field.
The by product molasses that produce in the cane sugar manufacture industry, in the west, most country uses it for directly to feed livestock; In China, major part is to be used for fermentation to make edible ethanol, consequently, because alcohol slops contains high concentration of COD (chemical oxygen demand), BOD (biological oxygen demand (BOD)) and SS (suspended substance), directly discharge the waters in large quantities and caused serious pollution to natural ecological environment.For a long time, handle at molasses alcohol waste liquid, industry member and scientific and technological circle have all dropped into a large amount of funds, human and material resources, also still do not have good especially technology resolution so far.
The improvement of molasses alcohol waste liquid at present mainly contains the resolution of three major types.(1), alcohol slops is handled irrigation and drainage farmland later on through some.This method only is suitable for having outside factory big area can bear purification of waste water, the non-sandy soil farmland enforcement of lack of water again, otherwise waste liquid can infiltrate rivers or underground water source, causes pollution; If dispensing is improper, organism also can burn out the crops.Discharging in a large number is difficult to operation on agricultural for the moment.(2), anaerobism biogas---the quick-fried gas of oxygen consumption pool method.The COD of molasses alcohol waste liquid is generally about 100,000 mg/L, after an anaerobically fermenting, the COD load also has 20000-30000 mg/L, still belong to high-concentration waste liquid, Digestive system after the fermentation, it is black, frowziness, surrounding environment is difficult to accept, and the investment and the working cost on the quick-fried gas of the oxygen consumption pool are also big.(3), alcohol slops processing and utilizing in addition again after concentrating, as make fuel, feed, fertilizer, water reducer, stopping agent, tackiness agent etc.Adopt multi-effect evaporation system to come molasses alcohol waste liquid is concentrated, because the pH value of waste liquid is lower, greatly between 3.4--4.8, waste liquid is the liquid of the complex mixture of inhomogeneity, many components in addition, make the facility investment and the operation of vapo(u)rization system, energy consumption cost is all too big, in the improvement engineer operation of waste water, becomes a white elephant of enterprise.
Same, in other the processing of organic liquid waste of food, fermentation industry, also there are above-mentioned common issue with and difficult point.
Since the early eighties, the primary pollution source of cane sugar factory, the improvement of molasses alcohol waste liquid is the major research item that people are engaged in always, and the appearance of many resolutions and improvement engineering is successively arranged.Japan consonance fermentation company is mixed with organic concentrated solution is mixed the stacking fermentation with the bark of pulverizing after again--inorganic composite fertilizer; Treatment process of the molasses alcohol waste liquid of Chinese patent application CN1078215A (April 30 1992 applying date) or the like.Its process technology scheme all is with the indispensable operational path of simmer down to, so facility investment height, energy consumption was big when operation was produced, the preparation of its compound manure all is the simple mixing and the preparation of one-plus-one, the activity that does not have soil microorganisms in the fertilizer, do not have with natural microorganisms improve, the effect of activating soil.
Purpose of the present invention is exactly at the deficiencies in the prior art part, and all contaminants in molasses alcohol waste liquid and the production of sugarcane sugar industry is all fully utilized, and the product after the comprehensive utilization no longer brings secondary pollution.It shows the comprehensive utilization of all refuse waste liquid highlightedly, not disposable simple mixing and preparation, but stage by stage according to the condition of different biochemical reactions, an amount of in batches adding, while is according to the situation of material, add various adjustment agent and carry out biological fermentation, have science with the relevant microbial population of introducing.For example, the first step at biological fermentation, be in the thermophilic fermentation, utilize airborne natural aerobic bacteria and material itself with microbial strains, under the gas blower ventilation condition, the heat energy by biological respinse produces carries out thermophilic fermentation, making constantly has steam row to escape in the atmosphere, reaches the purpose of a large amount of alcohol slops moisture of evaporation; In the final step of biological fermentation, introduce and to contain a large amount of soil microorganisms (mushroom etc. that comprises saprophytic property microorganism, humic acids bacterium, vinelandii, potassium solubilizing bacteria, phosphate solubilizing bacteria and can regulate and promote plant growth) and trace compound.The ecology that makes organic composite fertilizer and useful soil microorganisms form nature is coordinated system, thereby makes a kind of organic composite fertilizer with soil microbial activities.
This active organic composite fertilizer is used for agricultural; can draw useful soil microorganisms and grow in the soil of plant rhizosphere; make them become the natural process factory of underground fertilizer and the health doctor of plant; with organic composite fertilizer improve, activating soil; farm crop are grown better, preserve the ecological environment simultaneously and people's physical and mental health.
Technical scheme of the present invention, the first step is a thermophilic fermentation, utilize the bagasse of cane sugar factory, alcohol slops (or the cassava alcohol waste liquid etc.), filter mud, mud (pond sludge, river silt, ooze, the mud of city or sugar refinery sewage disposal etc.), the processing of giving through classification property, after mixing according to a certain percentage, utilize airborne natural aerobic bacteria and material itself with bacterial classification, in large fermentating pool, carry out thermophilic fermentation, bottom and middle part at large fermentating pool are placed with airduct, utilize gas blower that the fermentation material is constantly ventilated, whole fermentation vat all is under high temperature and the airy condition, makes to enter the moisture that warm air the atmosphere is taken away a large amount of alcohol slopss from the surface of fermentation materials.The mixed fermentation adjustment period that second step being transport the material that comes from the thermophilic fermentation pond, drops into saprophytic property microbial bacteria population, add and adjust agent and clay, become section triangle to stack the bottom of heap material, be provided with vent-pipe, to adjust the air permeability and the temperature of compost fermentation.According to the humidity condition of material, in the fermentation material, spray in time through the alcohol slops after giving processing.The 3rd step was a composting fermentation, with the bank turning after the above-mentioned fermentation once, according to the humidity of material, sprayed into the alcohol slops after process is given processing, became section triangle to stack, and no longer carried out artificial air blast ventilation, the yeast phase turning.The 4th step was the soil activation microbial fermentation.In above-mentioned fertilizer heap, add material with soil activation microbial population, with refuses such as the boiler chimney ash that produces in the industrial production, pulverized slag, lime ground-slags, suitably add some trace compounds, turning becomes section triangle to stack fermentation then, turning between yeast phase, it is more even that whole mixing of materials is got, and biological activity is more stable, after this, the active organic compound fertilizer finished product just can in bulk or dry back granulation packing dispatch from the factory.
Technical process of the present invention is as follows: the pre-treatment of alcohol slops is adjusted between the 4.0-5.5 with the pH value of lime (or potassium hydroxide, sodium hydroxide) with alcohol slops; Mud was pulverized 20 mesh sieves through seasoning, mixed and stirred material proportion (weight percentage): bagasse 25-35%, alcohol slops 50-70%, filter mud 0-20%, mud 0-20%.The first step, with above-mentioned mixing of materials and stirring, utilize the natural bacterial classification of natural aerobic bacteria and material bagasse in the air, filter mud, mud band itself, carry out thermophilic fermentation in fermentation vat, leavening temperature is 60-80 ℃, fermentation time is 7-12 days, in the meantime, adopt gas blower and breather line constantly in fermentation vat, to advertise air, spray into PH and be 4.0～5.5 alcohol slops, the amount that sprays into alcohol slops is not outwards oozed out waste liquid degree of being, turning therebetween 1-3 time with material.After the fermentation ends, the material with 1/5 returns to mix and stirs workshop section, and 4/5 material is gone into next procedure.Second step, the material that comes from above-mentioned workshop section, when beginning to produce, need to add the material that is rich in mould bacteria microorganism (be the mashed vegetables heap of the top layer earth that contains a large amount of septic plant residues, rotten fruit etc. the forest of gathering in 150 kilometers the scope around the local production site, its consumption generally is controlled in the scope of 0-4% of fermentation materials gross weight);
