Solar anaerobic-aerobic film reactor

Abstract

The invention discloses a solar anaerobic-aerobic film reactor which comprises a water inlet and distribution chamber, an anaerobic reaction chamber, a precipitation and filtration chamber, a sludge circulation system, an aerobic reaction chamber and a solar heat collection cover, a shell of the water inlet and distribution chamber is of an inverted conical barrel structure and is arranged on the lower portion of the anaerobic reaction chamber, the anaerobic reaction chamber is of a circular truncated cone barrel structure and is arranged on the lower portion of the aerobic reaction chamber, shells of the aerobic reaction chamber and the precipitation and filtration chamber are of a cylindrical barrel structure, and the precipitation and filtration chamber is arranged outside the anaerobic reaction chamber and the aerobic reaction chamber in a nested mode to form nested structure with the same center of the circle, The solar heat collecting cover is of a concentric nested structure and is arranged at the upper parts of the aerobic reaction chamber and the precipitation filtering chamber; the water inlet and distribution chamber is communicated with the anaerobic reaction chamber, the anaerobic reaction chamber is communicated with the precipitation and filtration chamber, and the precipitation and filtration chamber is communicated with the aerobic reaction chamber; according to the invention, the biodegradation efficiency is improved, the operation cost is reduced, and the purpose of improving the effluent quality is also achieved. The device can be applied to treatment of various high-concentration sewage for reuse of reclaimed water.

Description

technical field [0001] The invention belongs to the field of environmental engineering and relates to sewage treatment technology, in particular to a solar anaerobic and aerobic membrane reactor. Background technique [0002] In the case of increasingly scarce water resources in our country, the recycling of sewage has become the main way to solve the shortage of water in cities and towns, and it is also an important means to reduce the pollution of water resources and the environment. Therefore, it is of great significance to vigorously research and develop sewage resource utilization technology for our country to realize the strategic decision of sewage resource utilization. [0003] Membrane bioreactor, as one of the advanced technical methods for sewage purification and reuse, has been generally recognized and favored by experts and professors in the water treatment industry. This advanced technical method combines traditional water treatment technology and modern water ...

AI Technical Summary

Problems solved by technology

At the same time, there are also some deficiencies, mainly manifested as uneven distribution of water, short-flow phenomenon is very easy to occur, the activity of biological bacteria is greatly reduced, which seriously affects the biodegradation efficiency; the circulation pipeline is easy to block, and the three-phase separation effect is not good. , to a certain extent, affects the water quality of the effluent

It is precisely because of the above shortcomings that hinder the development and application of this technology to a certain extent.
