Device and method for treating domestic sewage in different seasons through soil infiltration method

Abstract

The invention discloses a device for treating domestic sewage in different seasons through a soil infiltration method. The device mainly comprises five parts, namely a nano aeration ablation device, an alternate-flow soil infiltration system, a turbine screen filter and a settling pond. The invention also discloses a method for removing organic matters, inorganic matters, microbes, heavy metals and the like by utilizing the device. By adopting the device and method, contaminants with low biodegradability and high relative molecular mass are completely oxidized and degraded, bacteria and pathogenic bacteria in the sewage are killed, hormones and other complex organic matters are digested, and sterilization and disinfection effects are achieved. Aiming at the conditions that the environmental deviation of temperature and humidity in different seasons is large and the treatment environmental deviation is obvious, the effluent can reach a national primary standard.

Description

technical field [0001] The invention relates to a device for treating domestic sewage by flori diatomite percolation method, and more particularly relates to a device for treating domestic sewage in different seasons by multifunctional soil percolation method. [0002] The invention also relates to a method for removing organic matter, inorganic matter, microorganisms, heavy metals, etc. in sewage by using the above-mentioned device. Background technique [0003] As an economical and efficient ecological sewage treatment technology, the alternating flow soil infiltration system is more and more widely used. After nearly 50 years of development, there are currently more than 10,000 alternating flow soil infiltration systems in the United States and more than 800 alternating flow soil infiltration systems in Denmark. Sewage treatment, but the alternating flow soil infiltration system is greatly affected by factors such as seasons and temperature. The removal rate of pollutants...

Problems solved by technology

[0003] As an economical and efficient ecological sewage treatment technology, the alternating flow soil infiltration system is more and more widely used. After nearly 50 years of development, there are currently more than 10,000 alternating flow soil infiltration systems in the United States and more than 800 alternating flow soil infiltration systems in Denmark. Sewage treatment, but the alternating flow soil infiltration system is greatly affected by factors such as seasons and temperature. The removal rate of pollutants in low temperature winter is lower than that in high temperature season, especially N, P and other pollutants, which affect its performance in low temperature areas in winter. promotional use of
