Application of Weifang Quartz Sand

&Application of Quartz Sand: The vast majority of sewage treatment plants in my country implement the first-level standards in the "Pollutant Discharge Standards for Urban Sewage Treatment Plants", and the implementation of the first-level standards can remove phosphorus and denitrification of sewage to the greatest extent &r, reducing the pollution to subsequent receiving water bodies, and the effluent can be used as reused water to solve the problem of water shortage in some areas of our country.
The tail water from the sewage plant enters the bottom of the filter through the water inlet pipe. It distributes water evenly through the water distributor and then passes through the filter material layer from top to bottom. During this process, the tailwater is filtered and contaminants in the water are removed. At the same time, the content of pollutants in the quartz sand filter material increases, and the degree of pollutants in the lower filter material layer is higher than that of the upper filter material. At this time, open the air lift pump located in the center of the filter and lift the quartz sand filter material in the lower layer to the sand washer on the top of the filter for cleaning. After the filter sand is cleaned, it is returned to the filter bed and the pollutants generated by the cleaning are discharged.
The quartz sand filter material moves from top to bottom under the action of the lifting pump, which stirs the tail water. The filter material in the filter can be cleaned in time and has strong resistance to the impact of pollutant loads. The special internal structure of the quartz sand filter and its own operating characteristics enable coagulation, clarification, and filtration to be completed in the same pool.
