Description
Technical field
The invention belongs to the water treating equipment technical field, relate to the manufacture paper with pulp method and apparatus of waste water of a kind of small-bore rolling ultrafiltration membrane treatment.
Background technology
The waste water of manufacturing paper with pulp is mainly derived from the process of manufacturing paper with pulp and tobacco sheets by paper making method production process of pulping and paper-making.
Pulping and paper-making machine hand section waste water is called plain boiled water, and it derives from the paper machine room paper making process.Plain boiled water mainly contains fiber fines, filler, coating and lysed timber composition, and the sizing material that adds, Wet Strength Resin, sanitas etc., is main with insoluble COD, and biodegradability is lower, and the sanitas of its adding has certain toxicity.The plain boiled water water yield is bigger, but its contained organic pollution load is well below black digestion liquid and middle-stage wastewater.Dialogue water treatment and reuse are significant to conserve water resource, minimizing pollutant emission.
China is a tobacco planting big country, and it is one of important technology of tobacco waste regeneration comprehensive utilization that paper process is made tobacco sheet.Utilization should the resulting tobacco sheets by paper making method of technology has that density is little, releasing content of coke tar low and characteristics such as chemical ingredients is controlled, is effective technology of present production " health type " cigarette.But paper process is made the tobacco sheet technology and is needed to use technologies such as slurrying, the papermaking working method of manufacturing paper with pulp and natural product extraction separation; Produce a large amount of waste water in the production process; One ton of tobacco sheet of every production will produce the organic waste water of 50-120 ton; Throughput is 10,000 tons/year production line, and day wastewater treatment capacity is up to 2000-2600m
3/ d.Directly discharging can cause environmental pollution.
The general character of the existing paper waste of waste water that produces in the tobacco sheets by paper making method production process is as containing fiber fines; Have again simultaneously in tobacco wastewater colourity height, the waste water and contain characteristics such as the disadvantageous nicotine of microorganism growth; Paper process tobacco wastewater water quality is very big with tobacco leaf kind difference and production process fluctuation simultaneously, COD
CrFrom 1500-250000mg/L; Belong to high concentrated organic wastewater, colourity is dark (being reddish-brown), and SS is higher; Redox potential is higher; It is rotten etc. that waste water is prone to corruption, considers that therefore the tobacco sheet wastewater from paper machine directly handles the reuse problem and be significant, for the water resources of practicing thrift worsening shortages and alleviate environmental pollution and be significant equally.
Air supporting is a kind of water technology of uniqueness; Can produce microbubble through certain mode; Thereby adhere to density in the water and approaching solid or the liquid impurity particulate of water, form the air float body of density, effectively remove materials such as suspended substance in the waste water, fiber, algae less than water.It is even that efficient air-floating forms bubble, can suck and dissolve enough oxygen, is issued to higher daf efficiency in the less situation of reflux ratio.
Membrane technique has advantages such as high-level efficiency, less energy-consumption, normal-temperature operation and easy amplification.Ultrafiltrationmembrane process is that a kind of pressure difference with the film both sides is a motivating force, is filtration medium with the ultra-filtration membrane, with the relevant screening process of membrane pore size size.Ultrafiltration is a kind of physical separating process, and any phase transformation does not take place.Utilize the characteristic that ultra-filtration membrane can separate substance; Select the ultra-filtration membrane of suitable molecular weight cut-off for use; Can hold back materials such as suspended particulate, Mierocrystalline cellulose and lignin class in the waste water of manufacturing paper with pulp, colloidal particle, bacterium, become liquid concentrator, further handle the back reuse as slurry; See through liquid directly as the reuse of production cycle water.The rolling ultra-filtration membrane is few because of its current dead angle, anti-pollution, characteristics that crushing resistance is good have been widely used in feed separation and water treatment various fields such as food-processing, drink industry, medicine industry, biotechnological formulation, Chinese medicine preparation, clinical medicine, dyeing waste water, food industrial wastewater processing, resource recovery, environmental engineering.
