Rural sewage treatment integrated device

Abstract

The invention discloses a rural sewage treatment integrated device. The rural sewage treatment integrated device comprises a water inlet pipe, a sewage treatment tank body and an aeration device, wherein the interior of the sewage treatment tank body is divided into an anaerobic zone, an anoxic zone, an aerobic zone and a settling zone which are sequentially communicated. The water inlet pipe is communicated with the anaerobic zone. The anoxic zone and the aerobic zone are aerated through an aeration device. A cobweb type micro-electrolysis treatment system is arranged in the aerobic zone. A clear water area is arranged on the upper side of the settling area, is communicated with the settling area through meshes and is connected with a water outlet pipe. Firstly, the device has the advantages of low investment, low energy consumption, small occupied area, convenience in management and convenience in maintenance; secondly, the device can collect sewage in a small range for on-site treatment, the sewage treatment effect is good, and the treatment efficiency is high. Moreover, the device has outstanding progress in the aspects of denitrification and dephosphorization, and is suitablefor being widely popularized and applied in vast rural areas.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to an integrated equipment for rural sewage treatment. Background technique [0002] With the rapid development of my country's economy and the improvement of the quality of life in rural areas, the amount of domestic sewage produced in rural areas has also increased. Rural sewage generally contains high concentrations of organic matter, nitrogen and phosphorus, and the discharge is scattered and difficult to collect centrally. The management cost of centralized discharge is high, the treatment efficiency is low, and the energy consumption is high. At present, there are still many rural sewage collection pipe networks and sewage treatment infrastructures that are seriously behind. Untreated sewage is directly discharged to low-injection places or into surrounding water bodies, which seriously affects and damages the health of the people and is not conducive to the sustainab...

AI Technical Summary

Problems solved by technology

[0005] The existing sewage treatment equipment in rural areas has not been widely promoted and applied. The reasons include that the sewage is not convenient to discharge on the spot and the treatment is troublesome; and the sewage treatment equipment is not perfect and the effect is not good, especially in nitrogen and phosphorus removal It has not been effectively improved, and the quality of sewage treatment is poor, making rural water pollution worse and worse, and people's healthy life is threatened
