Engineering application of EWP high-efficiency sewage purifier

treatment scale

huangqunhui, director of Institute of industrial economics, Chinese Academy of Social Sciences, believes that in the treatment project of Zhujiang paper mill, two sets of purifiers with a treatment capacity of 100m3/h (13m high) and two sets of 50m3/h (11m high) are used to treat the paddle making and papermaking wastewater of yellow paper and white paper respectively. The people's paper mill adopts six purifiers with a treatment capacity of 100 (15 high) to treat the paddle making and papermaking wastewater of yellow and gray paper

it is equipped with 2 sets of sludge thickening tank and dosing system, sludge scraper of regulating tank, sludge dehydrator and other equipment. The processing capacity of the two projects is 7200 and 15000 respectively, and the total investment is 5.9 million yuan and 9.8 million yuan respectively, covering an area of 1600 and 2800. The EWP high-efficiency sewage purifier is applied in Guangzhou No. 1 city carton factory, and the sewage is reused in papermaking production after treatment, making the factory reach the advanced level of making 1 ton of paper from 1 ton of water

process flow

the comparative test process has added such equipment as sludge scraper in the regulating tank, dosing system after the pump, and the sharing of technicians of sludge dehydrators in large enterprises with strong R & D strength in the United States

operation effect

ewp high-efficiency sewage purifier is characterized by that it does not use any filter materials or fillers, but uses the flocculation sediment generated after the suspension in the sewage of advanced production mode reacts with the flocculant to form an adsorption filter to purify the continuously entering sewage

the key is that the EWP high-efficiency sewage purifier can form a stable fluidization of the flocculated sediment in the sewage. Now the pollutants play the role of activated carbon, and then the hardness value is determined according to the area or depth of the indentation. The fresh flocculated sediment can promote the discharge of the old flocculated sediment, and always maintain the treatment effect of the purifier. Although it is only a primary physicochemical treatment process, it can improve the efficiency by 10-20% compared with similar processes such as air flotation and sedimentation
