Problems solved by technology

[0007] The purpose of the present invention is to solve the problem that the pre-coated dynamic film obtained by the pre-coated film filter of the existing high-ammonia-nitrogen water source water treatment device is easy to cause bias flow inside the filter due to uneven film laying, resulting in an increase in the pressure difference of the filter and shortening the operating cycle. shortening, filter element pollution, and deterioration of effluent water quality, and provide a modified rice husk ash pre-coating device for treating rural high-ammonia nitrogen water source water

Abstract

The invention relates to a high ammonia-nitrogen water source water treatment device and a method used for treating sewage, and more specifically discloses a modified rice hull ash pre-coated film device used for treating rural high ammonia-nitrogen water source water, and a method used for treating rural high ammonia-nitrogen water source water using the modified rice hull ash pre-coated film device. The method is used for solving problems that filter differential pressure is increased, operation period is shortened, filtering elements are polluted, and deterioration of effluent quality is caused because of bias flow generated in filters, wherein bias flow is easily caused by nonuniform spreading of precoated dynamic membranes obtained by pre-coated film filters of conventional high ammonia-nitrogen water source water treatment devices. The modified rice hull ash pre-coated film device comprises an inlet sump, an additive bucket, a precoating bucket, a sewage pool, a pre-coated film filter, and an outlet sump. The method comprises following steps: 1, preparation of 4A molecular sieve; 2, liquid filling period; 3, film coating period; 4, filtering period; and 5, backwashing period. The invention mainly provides the method used for treating rural high ammonia-nitrogen water source water.

Description

technical field [0001] The invention relates to a high ammonia nitrogen source water treatment device and a method for treating sewage. Background technique [0002] The drinking water facilities in my country's rural areas are mainly traditional and backward decentralized water supply, which is quite different from urban water supply. The problem of rural drinking water safety needs to be solved urgently. In 2006, the State Council successively reviewed and passed the "Eleventh Five-Year Plan for National Economic and Social Development" "Outline" and "National Rural Drinking Water Safety Project "Eleventh Five-Year" Plan", both will accelerate the implementation of rural drinking water safety projects as key projects in the construction of new countryside. During the "Eleventh Five-Year Plan" period, universities and scientific research institutes participated in the research of the key projects of the scientific and technological support plan of "Rural Safe Water Supply Co...
