Rural area domestic sewage collection and treatment ecological network system

Abstract

The invention discloses a rural area domestic sewage collection and treatment ecological network system, which includes a node formed from a biogas pool, an ecological pond, and an artificial wetland; and a link which connects each of the nodes and which is formed from a pipe and an ecological ditch. The biogas pool collects the sewage resulted from rural household toilets; the ecological pond collects and temporarily stores the domestic sewage resulted from kitchen uses, bathing uses and from the preliminarily treated biogas pool; the artificial wetland purifies and treats the collected domestic sewage; the pipe connects the hole of discharging domestic sewage of each rural household, the biogas pool and the biological pond, and transports the domestic sewage; the ecological ditch treats the sewage through the perennial water resistant and root developed plants, and acts as a link between the biological pond and the artificial wetland, and serially connects the whole biological network system of collecting and treating rural domestic sewage; the maintenance and management of the biological network system is simple, the running cost is low, the process is simple, and the operability is extremely strong.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, in particular to an ecological network system for collecting and treating rural domestic sewage. Background technique [0002] Compared with cities, the rural population density is low, the distribution is scattered, and the domestic sewage discharge area is wide, and the economic technology in rural areas is weak, and there is a lack of sufficient funds and professional technical management personnel. Therefore, the rural domestic sewage treatment methods cannot be copied or applied mechanically. The model must be made scientifically based on the actual conditions in the countryside and the characteristics of domestic sewage. In recent years, with the development of my country's rural areas and the rapid improvement of rural people's living standards, the discharge of rural domestic sewage has continued to increase. Rural domestic sewage is becoming one of the main reasons for the deter...

Problems solved by technology

[0004] The purpose of the present invention is to provide an ecological network system for the collection and treatment of rural domestic sewage, which aims to solve the problem that the rural domestic sewage does not form a network system for centralized treatment, and the existing sewage treatment effect is poor, and the removal effect of nitrogen and phosphorus is not good. The problem of low disposal rate
