Problems solved by technology

However, there are many hidden dangers in its device and method.
For example, the top-down water flow mode is easy to form short flow and contact blind area; the addition of activated carbon, zeolite and other materials will cause the device to be easily blocked and need to be replaced frequently; the raw water pollution of drinking water is low, and there is no treatment for solid carbon sources Demonstrate the characteristics of sewage with higher total nitrogen concentration, etc.
Another example is in the patent application for "an ecological barrier column and method for removing underground subsurface flow pollution (CN 103224286 A)",

Abstract

The invention discloses poly(butylene succinate) particles for a sewage nitrogen removal treatment device. The poly(butylene succinate) particles have an average particle size of 2.5-3.5mm, a specific surface area of 1.8m<2>/L, real density of 1.26kg/L and filling density of 0.9kg/L. The poly(butylene succinate) particles for the sewage nitrogen removal treatment device have good nitrogen removal effects.

Description

technical field [0001] The invention relates to polybutylene succinate particles for a sewage denitrification treatment device based on an artificially synthesized biodegradable polymer, which is specially aimed at the deep denitrification treatment of rural distributed domestic sewage. Background technique [0002] In recent years, with the rapid development of economy and society, the total nitrogen load of the decentralized sewage treatment system used to solve the problem of non-point source pollution in rural areas is increasing. However, although the upper limit of the total nitrogen concentration in my country's pollutant discharge standards (Class A standard is 15mg / L) is much higher than the maximum allowable values ​​stipulated by the United States and the European Union (respectively 3mg / L and 8mg / L), the decentralized The total nitrogen in the effluent of the sewage treatment system is still high, and a large amount of nitrogen nutrients are discharged into the en...
