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

Abstract

The invention discloses a composite anaerobic membrane bioreactor which is mainly composed of a reactor system, a near-infrared light irradiation system, an aeration circulating system, a sludge system and a water in / out system. The main body of the composite anaerobic membrane bioreactor is composed of a polyvinyl chloride (PVC) shell, and an immersed plate frame membrane component and a support plate are arranged at the inner center; polyvinylidene fluoride (PVDF) is selected as the main body part of the membrane, and an aeration device, a water inlet and a sludge storage bucket are arranged at the lower part of the membrane component; and a near-infrared LED lamp with wavelength of 850nm is mounted at the top of the reactor, and a water outlet and an exhaust port are formed above the reactor. With low energy consumption, the device can efficiently and synchronously remove high-concentration chemical oxygen demand (COD), total nitrogen (TN) and total phosphorus (TP) in domestic sewage; meanwhile, the problem of unsatisfactory effect of traditional sewage treatment method in intercepting pathogenic microorganisms and viruses is solved; and the device has remarkable advantages of small floor area, high purifying efficiency, rare generation of membrane pollution and the like.

Description

technical field [0001] The invention relates to a composite anaerobic membrane biofilm reactor and its application, belonging to the technical field of sewage treatment. 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 wate...
