Rural living sewage treatment system and method

Abstract

The invention discloses a rural living sewage treatment system and method. The system includes a reinforced pretreatment unit, a multi-segmental core biochemistry module and a tail end treatment unit;the reinforced pretreatment unit is provided with a sewage inlet for introducing sewage, and a water outlet of the reinforced pretreatment unit is connected with the multi-segmental core biochemistrymodule and the tail end treatment module in sequence; the tail end treatment unit is provided with a water outlet. The treatment effect of the treatment system can be equal to or even superior to a prospective treatment effect, and the running effect is stable; since the process of the method is merely a biofilm process, running and maintenance are simple, and the problems of sludge loss, difficult biofilm formation and the like are avoided; since artificial biofilms are adopted, the formation of the biofilms can be controlled manually, the film formation time is greatly shortened, the biological variety is specific, the adaptability is high, and the biofilms can be reused and have obvious advantages.

Description

technical field [0001] The invention relates to the field of domestic sewage treatment, in particular to a rural domestic sewage treatment system and method. Background technique [0002] In recent years, with the continuous improvement of my country's economic development and people's living standards, the problem of rural water environment pollution has gradually become an important factor restricting the construction of new urbanization. In April 2015, the "Water Pollution Prevention and Control Action Plan" or the "Water Ten Measures" was released, calling for the promotion of agricultural and rural pollution prevention and control, and the acceleration of rural environmental improvement, once again making rural water environment governance the focus of attention. [0003] At present, my country has a rural population of 674 million, distributed in more than 2.6 million natural villages, and produces more than 30 million tons of domestic sewage every day. However, sewage...

Problems solved by technology

However, at present, this process is also commonly used in rural domestic sewage treatment projects. Severe sludge loss requires regular sludge input and insufficient biofilm on the filler (basically no biofilm or biofilm is covered with thick inorganic sludge, which will not work. ), complex maintenance and management, unstable effluent quality, etc.
