Rural sewage comprehensive purification system

Abstract

The invention relates to the field of rural sewage purification, in particular to a rural sewage comprehensive purification system. The system comprises a plant ecological membrane reactor and an ecological infiltration tank, and a sedimentation tank is arranged on one side of the plant ecological membrane reactor; the upper side of the sedimentation tank is communicated with the lower side of the plant ecological membrane reactor through a pipeline, and sewage on the upper layer of the sedimentation tank is pumped into the plant ecological membrane reactor through a water pump; a plant ecological membrane reactor filter element is arranged in the plant ecological membrane reactor; one side of the upper part of the plant ecological membrane reactor is communicated with the upper part of the ecological infiltration tank through a pipeline; the ecological infiltration tank is filled with multi-stage permeable ecological restoration filler from top to bottom; and a purified water outflow pipeline is arranged at the bottom of the ecological infiltration tank. The system can perform solid-liquid separation on rural basic sewage, including daily sewage, excrement, urine and other solid-liquid mixtures, deodorize the sewage and remove heavy metals, and finally reach the dischargeable standard.

Description

technical field [0001] The invention relates to the field of rural sewage purification, in particular to a comprehensive purification system for rural sewage. Background technique [0002] The problem of wastewater polluting the environment is becoming more and more serious, and the most effective and environmentally friendly method is the biological filtration method, which uses microorganisms and green plants into the purification pool at the same time to form a multi-level purification pool that can be recycled to achieve good purification. Effect. [0003] However, the current purification tanks on the market are fixed and not easy to disassemble, and when planting plants, they cannot be used for plants with different lengths of initial root systems. At the same time, microbial fillers will be knotted when the water flow is turbulent, which is not easy for later maintenance. The disadvantages of the prior art are: the amount of rural sewage is small, the water amount fl...

AI Technical Summary

Problems solved by technology

[0003] At present, the purification tanks on the market are fixed and difficult to disassemble, and when planting plants, they cannot be used for plants with different lengths of initial root systems. At the same time, microbial fillers will be knotted when the water flow is turbulent, which is not easy for later maintenance.

The disadvantages of the prior art are: the amount of rural sewage is small, the water amount fluctuates greatly, the pollutant index is unstable, sometimes the pollution concentration is high, and sometimes the pollution concentration is low; Ecological restoration and beautification, and high operating costs, do not save energy
