Abstract

The invention discloses sewage treatment equipment combining micro-nano bubbles and a membrane bioreactor, and belongs to the technical field of sewage treatment equipment. The equipment comprises anadjusting tank, an integrated sewage treatment device, a disinfection unit, a micro-nano bubble generator and a micro-nano bubble aerator, and the integrated sewage treatment device is sequentially provided with an anoxic zone, a first aerobic zone, a second aerobic zone and an MBR zone in the sewage treatment flow direction. The micro-nano bubble aerator is arranged at the bottoms of the first aerobic zone and the second aerobic zone, and the micro-nano bubbles are combined with the membrane bioreactor, so the treatment performance of the integrated sewage treatment device is improved, the hydraulic retention time is shortened, the occupied area is saved, the process is a low-energy-consumption and high-efficiency village and town domestic sewage treatment process, the removal rate of indexes such as nitrogen, phosphorus and the like can be improved, the biodegradability of the sewage can be improved, the decomposition capability of refractory pollutants is improved, and up-to-standard discharge of the sewage is ensured.

Description

technical field [0001] The invention relates to sewage treatment equipment combining micro-nano air bubbles and membrane bioreactors, and belongs to the technical field of sewage treatment equipment. Background technique [0002] With the rapid growth of my country's population and the accelerated development of industry, water pollution has become an increasingly serious global problem. During this period, due to the unbalanced development between urban and rural areas, domestic sewage treatment in rural areas in my country has received less attention and corresponding capital investment. At present, China is the largest developing country in the world, and the scale and number of townships are rapidly expanding. The corresponding development of domestic sewage treatment facilities and residents' awareness in villages and towns has not kept up. According to statistics, more than 95% of untreated domestic sewage and fecal sewage are directly discharged into natural water b...
