Firstly, simple sewage treatment equipment includes septic tank, buried sewage treatment equipment, air flotation machine, mbr water recycling equipment, mbbr sewage treatment equipment, sbr sewage treatment equipment, BAF biological aerated filter, ic anaerobic reactor, UASB anaerobic tower, WD micro-electrolysis reactor, ammonia nitrogen stripping tower, chlorine dioxide generator, grid and drum filter.
Characteristics of MBR process:
(1) can effectively carry out solid-liquid separation, and separate suspended solids, colloidal substances and microbial flora lost from biological units in wastewater from purified water. The separation process is simple, the occupied area is small, the effluent quality is good, and it can be reused without tertiary treatment.
(2) The biomass in the biological treatment unit can be maintained at a high concentration, thus greatly increasing the volume load. At the same time, the high efficiency of membrane separation greatly shortens the hydraulic retention time of the treatment unit and correspondingly reduces the occupied area of the bioreactor.
(3) Because it can prevent the loss of various microbial flora, it is beneficial to the growth of slow-growing bacteria (nitrifying bacteria, etc.). ), so that various metabolic processes in the system can be carried out smoothly.
