Abstract
Application Manual in Collection and Regulation of Rural Well-off Residence Technology proposes indexes of comprehensive harmful treatment and utilization rate on treatment and utilization of both domestic waste and sewage. The invention, according to the common characteristic that the domestic waste and the sewage are both composed essentially of organic matters, discloses an integrated biological method for treating. The method comprises: first allowing facultative bacteria of a domestic waste heap to ferment and decompose the waste and realizing harmless treatment with the high temperature got in bacterial metabolism; using the produced CH4 for cooking; sorting the residuals for separate use; allowing the sewage (including sewage produced by organic decomposition) with the waste to flow over a gentle slope land (a land treating system) for further purification by aerobic bacteria and plants to remove VOD and COD contained therein so that all water can meet the discharge standard for rational utilization as a resource. The water can be used for farmland irrigation or groundwater replenishment or be transmitted as heating (cooling) carrier to residential areas for underground heating or cooling. The method is exceedingly simple, the utilization is thorough, and no secondary pollution exists.
Description
The present invention is the important branch of environmental engineering in the environmental science, solid waste and sewage treatment project.
The now existing many methods of solid waste disposal and sewage disposal, all there is the treatment facility to them each big and medium-sized cities at present, but its investment is big, working cost is also big, so be difficult to build in small city and enterprise, though also have built related facility, still have because of working cost is too high need not, or the ground discontinuous running that overtly agrees but covertly oppose, tackle the inspection of environmental administration with facility pendulum sample.Village-town house both has been subjected to restrictions such as fund, place because dispersion also because solid waste and sanitary sewage amount are few, be built treatment facility, also has the few dispersion of Ling Xing Search collection and amount to give and utilizes the inconvenience that is brought.But villages and small towns solid waste and sanitary sewage are multi-point and wide-ranging, as not handling, do not reach innoxious, and environmental problem just is difficult to solve.Protection villages and small towns environment is exactly an empty verbiage, and it is also impossible to eliminate water pollution source.Integrated and the pilot project " declaring notice " of the provincialism villages and small towns comfortable house technology that building portion carries out, to East China, south China, Central China ... all propose requirement to the processing rate and the utilization ratio of solid waste and sanitary sewage in 7 districts, importance that it serves to show this two problem is with urgent.
The maximum common feature of villages and small towns rubbish and sewage is based on organism, and organism is the grain of microorganism.Therefore, it is fully feasible handling together with biological method, and this does not have the easier enforcement of severe cold area in the winter.
The present invention proposes that rubbish and sanitary sewage are unified to be solved and to the method for its 100% harmless treatment with utilization, it is enforcement (Figure of description) like this:
Following wind direction in the Residential areas selects a highland and adjacent larger area gentle slope, and the highland is dug several holes and cheated as dumping, and they use in turn, one when being filled with, with the sanitary sewage cast wherein, form reducing environment, make it fermentation with anaerobic bacterium and decompose organic; Produce high temperature, kill various microorganisms; The new sewage that sanitary sewage that injects and organic matter decomposition form oozes out at the bottom of the pond, in shallow water cross flow mode, flows through the gentle slope, makes land system and handles, and by the further degradation of organic substances of aerobic bacteria, reduces BOD, absorbs COD by humidogene, marsh plants.At the toe water channel treated water is concentrated, through water quality detection is qualified reach emission standard after, select suitable purposes again: 1. make farmland irrigation water; 2. recharge groundwater; 3. transfer to the underground of comfortable house district, villages and small towns as heat accumulation (cold) medium by adiabatic PPR pipeline, divide hot and cold pond to store.Winter water summer grade is to reduce the garden temperature; Xia Shuidong usefulness, but heat supply water and heating.
During addressing, except that considering landform, also should investigate local hydrogeological conditions.Desirable address is at the bottom of the pond and thicker and stable water-resisting layer is arranged under the gentle slope, in order to avoid in solid waste and sewage treatment process generation seepage, recharge groundwater before water quality does not reach emission standard becomes the groundwater pollution source.In the area of not stablizing water-resisting layer, available laminated plastics shop fixtures causes artificial water-resisting layer.
The contriver several years ago has the bacterial strain (being aerobic bacteria) of potassium decomposing, phosphorus decomposing and solid oxygen effect always in nature screening, they can make various crop yields 15%～150% (and regard species and local soil as, weather condition are different) as bio-feritlizer.Known: as to be rich in organic potassium (containing in the plant materials) and inorganic potassium (clay, sand grains, ashes etc. contain) in the rubbish; Potassium solubilizing bacteria can resolve into them water-soluble potassium ion (available potassium in the fertilizer).In the sanitary sewage, be rich in organophosphorus (agricultural chemicals that washs on the fruits and vegetables mostly is organophosphorus, the also organophosphoruss that contain of washing composition more) and inorganic phosphorus (containing in the sewage that vegetable cleaning produces); Phosphate solubilizing bacteria can resolve into them rapid available phosphorus (phosphate fertilizer).Vinelandii can be decomposed organic in breeding, and the phosphorus potassium in the consume water is converted into nitric nitrogen or ammonia-state nitrogen (fertilizer) with airborne nomadic nitrogen, for the plant-growth in the land treatment system.Therefore, these bacterium liquid (kind) are regularly sprayed to the upstream, gentle slope, can make the thriftiness growth (this can remove a large amount of COD and some heavy metal, particularly absorbs a large amount of potassium and phosphonium ion) on it, purification of water quality.Through the sewage that these bacterial strains purify, COD and BOD seldom-can reach emission standard.Remaining potassium seldom and phosphonium ion in the water can be the irrigated land plant and absorbs, and wherein certainly exists the bacterial strain (harmless bacterial strain) of above-mentioned inoculation, can be in the irrigated land breeding, be plant for fertile, play the bio-feritlizer effect.
In the accompanying drawing: 1 is place where the garage is piled up (disliking the aerobe fermentation pond); 2 is ground, gentle slope (land treatment system, aerobic bacteria are divided phosphorus decomposing potassium etc.); 3 are the fermentation vat outlet; 4 is collecting gutter; 5 is water out up to standard; 6 for stacking a peripheral catch drain; 7 is water-resisting layer (clay seam etc.); 8 is pedosphere; 9 are humidogene, marsh plants (selecting some plants strong to the heavy metal receptivity); 10 is rainproof gas skirt; 11 is venting port.
The sanitary sewage amount that general comfortable house district, villages and small towns is produced is all greater than quantity of solid waste, so the entire treatment process should avoid rainwater to add, in case stack the load of a sewage outflow and minimizing land treatment system, should around stacking the field, dig catch drain, the area that economic condition is arranged, can add rainproof gas skirt 10 on stack the field, it prevents in the sleet landing field, also gathers the gas that is decomposed to form by organism and (is mainly CH
4, also have a small amount of CO, CO
2Deng), this inflammable gas is drawn by vapor pipe 11, can make cooking gas near resident.
Place where the garage is piled up has a plurality of and adjacent, can use in turn, and water outlet is all towards the gentle slope, the current direction land treatment system.Rubbish is after long-term (several years) fermentation, and obvious decrement only can be left difficult decomposed substance and part mud such as insolubles such as fragment of brick, glass, pottery, metal and plastics.After all used in whole stackings hole, their resistates can focus on the clear water of annotating then in the pond and stir, according to the proportion difference separately with plastics, pottery and metal, and regeneration respectively then.
