Distributed anaerobic membrane bioreactor

Abstract

The invention discloses a distributed anaerobic membrane bioreactor. The distributed anaerobic membrane bioreactor is mainly composed of a reactor system, a near-infrared light irradiation system, anaeration circulating system, a sludge system and a water inlet and outlet system. According to the invention, a composite anaerobic membrane bioreactor main body is composed of a polyvinyl chloride (PCV) material shell; the center of the interior of the composite anaerobic membrane bioreactor main body is provided with immersion type plate-frame membrane assemblies and a supporting plate; polyvinylidene fluoride (PVDF) is selected as a membrane main body part; the lower parts of the membrane assemblies are provided with an aeration device, a water inlet and a sludge storage hopper; the top part of the reactor is provided with near-infrared LED lamps with a wavelength of 850 nm; and the upper part of the reactor is provided with a water outlet and a gas outlet. The invention has the following advantages: the device has low energy consumption, can effectively and simultaneously remove high-concentration chemical oxygen demand (COD), total nitrogen (TN) and total phosphorus (TP) in domestic sewage, solves the problem of poor entrapment of pathogenic microorganisms and viruses for a traditional sewage treatment method at the same time, and has the significant advantages of small occupied land area, high purification efficiency, insusceptibility to generating membrane pollution, etc.

Description

technical field [0001] The invention relates to a sewage treatment technology, in particular to a distributed anaerobic membrane bioreactor. Background technique [0002] In recent years, due to the continuous growth of the population and the continuous development of the economy, the pollution of fresh water resources has become increasingly serious. The shortage of fresh water resources has become a common problem in most parts of the world, which makes people focus on the utilization of recycled water. After a series of treatments, urban sewage is purified to meet the requirements of other industries and become reclaimed water for further use. Reclaimed water is also known as the second water source of the city. Compared with desalinated seawater and water transfer across river basins, the cost of reclaimed water is lower, which helps to reduce aquatic environmental pollution, and at the same time improves the comprehensive utilization of water resources. Whether it is F...

AI Technical Summary

Problems solved by technology

[0005] 1. Due to the high-intensity aeration method, it is easy to produce membrane pollution and the pollution is serious, which needs to be manually removed regularly;

[0006] 2. On the other hand, the use of high-intensity aeration and complex equipment further brings power energy consumption and increases the cost of water production
