Low-energy consumption aeration-free domestic sewage recycling apparatus

Abstract

The invention provides a low-energy consumption aeration-free domestic sewage recycling apparatus. The apparatus is mainly such structured that the bottom of the shell of an anaerobic reactor equipped with a stirrer is provided with a water inlet pipe and a sludge discharging and emptying pipe, an outer deflecting cover is arranged in the shell, an inner deflecting cover is arranged in the lower part of the outer deflecting cover, a gas vent is arranged in the top cover of the shell, an epitaxial part at the upper part of the shell is provided with internal and external vertical baffle plates, one end of a water draining pipeline is connected with the outer side of the external vertical baffle plate, the other end of the water draining pipeline is connected with the water inlet of a membrane module, the upper part of the membrane module is provided with a clear water outlet, one branch pipe of a concentrated water outlet pipeline of the membrane module is connected with a concentrated water outlet, the other concentrated water branch pipe is connected with a water inlet pipe on the top cover of the shell, and a sensor of a pH / ORP / temperature monitor is arranged in the shell. A liquid level automatic control system is composed of a pressure transducer, a liquid level controller, an electric actuator, a sewage pump and a solenoid valve, wherein the pressure transducer is disposed in the reactor. The low-energy consumption aeration-free domestic sewage recycling apparatus provided by the invention can treat domestic sewage, enables treated domestic sewage to reach the standard and retains nutrients like nitrogen, phosphorus and potassium in domestic sewage.

Description

technical field [0001] The invention relates to a device for reusing domestic sewage. Background technique [0002] At present, the lack of agricultural water resources and the harm of trace micro-pollutants in urban domestic sewage have become serious problems in the field of resources in our country. The key to solving these problems in our country is to use domestic sewage irrigation to open up a way for urban sewage disposal and agricultural water use. However, there are big problems in domestic sewage irrigation. The water quality of irrigation seriously exceeds the standard, the level of sewage treatment technology is low, the management of sewage irrigation is chaotic, the development of sewage irrigation is only for area, and the corresponding technology and scientific research work of sewage irrigation are seriously lagging behind. In order to scientifically irrigate farmland with domestic sewage, it is imperative to form a reasonable material and energy cycle syste...
