Papermaking Wastewater Treatment System Residential Areas Restaurants
The wastewater is first collected by the collecting basin, and then the coarse grid is used to intercept the suspended solids such as paper scraps, foam paper, plastic and large particles of impurities in the water, and then passed through the lifting pump into the fine grid to further remove fine particulate impurities and then enter the grit chamber. , remove the inorganic particles with a higher density in the water.
The effluent from the grit chamber enters the SBR pool. At this stage, the nutrients and nitrogen and phosphorus are removed. The night passes through the blower room and enters the flocculation reaction tank. The chemical flocculation and sedimentation removes the fine suspended matter floating matter and colloidal substances in the water. The pool is temporarily stored and finally disinfected by the UV disinfection tank. After the test is completed, it can be reused or discharged.
On the other hand, the excess sludge from the SBR pool and the sediment after the flocculation tank are collected by the mud collection well, then It enters the sludge concentration workshop for concentration, and then is sent to the sludge dewatering workshop for dehydration to obtain mud cake, which is processed regularly.
The paper industry uses wood, straw, reed, rags, etc. as raw materials, and the cellulose is separated by high-temperature and high-pressure cooking to make pulp. In the production process, the non-cellulose fraction that is finally discharged from the raw material is called papermaking black liquor. The black liquor contains lignin, cellulose, volatile organic acids, etc., which is odorous and highly polluting. The concentration of pollutants in black water is very high, and the BOD is as high as 5-40 g/L, which contains a large amount of fibers, inorganic salts and pigments. The papermaking wastewater discharged from the bleaching process also contains a large amount of acid and alkali substances.
Such wastewater treatment is very difficult, and it is difficult to meet emission standards by simple physical or biochemical treatment. Our company adopts high-efficiency air flotation + UASB anaerobic reactor + EGSB + contact oxidation process to treat papermaking wastewater, which can make the effluent discharge to the standard for a long time.
