Low-temperature-resistant dispersing type sanitary sewage treatment integrated device and treatment method thereof

Abstract

The invention provides a low-temperature-resistant dispersing type sanitary sewage treatment integrated device and a treatment method thereof. The low-temperature-resistant dispersing type sanitary sewage treatment integrated device comprises an adjusting tank, a first-stage anoxic tank, a first-stage aerobic tank, a second-stage anoxic tank, a second-stage aerobic tank, a third-stage anoxic tank, a third-stage aerobic tank, a secondary sedimentation tank, a solar heat collection system, a heat storage water tank and a heat exchanger. The adjusting tank is connected with the first-stage anoxic tank, the second-stage anoxic tank and the third-stage anoxic tank through a mechanical diaphragm metering pump and pipelines. The third-stage aerobic tank is connected with the secondary sedimentation tank. Filler is added to all stages of the aerobic tanks. Meanwhile, thermal insulation is conducted on a device shell, and heating is conducted through the solar heat collection system. The low-temperature-resistant dispersing type sanitary sewage treatment integrated device is small in occupied area, simple in operation, good in output water quality, convenient to maintain, low in operation cost, capable of being stably operated at a low temperature and capable of conducting dispersing type sanitary sewage integrated treatment.

Description

technical field [0001] The invention belongs to the field of sewage treatment, and in particular relates to a low-temperature-resistant distributed domestic sewage treatment integrated equipment and a treatment method thereof. Background technique [0002] The distribution of rural population in my country is scattered, and the sources of sewage are scattered. The traditional centralized sewage treatment requires high pipeline network construction costs, sewage treatment plant construction costs, and operating costs. It is difficult to apply to rural areas with relatively poor economic conditions, and decentralized treatment The method is more suitable for rural sewage treatment, and an integrated decentralized domestic sewage treatment equipment is urgently needed. [0003] The winter in Northeast my country is long and cold, and the freezing period lasts for 3-6 months. The average temperature of the lowest month in Northeast China (January) is below -10°C, the extreme temp...

AI Technical Summary

Problems solved by technology

[0007] The characteristics of the existing decentralized sewage treatment equipment are: (1) The traditional sewage treatment process is complex and inconvenient for operation and management; (2) The sewage treatment efficiency is low under low temperature conditions, especially the denitrification treatment is significantly affected by the low
