A high-efficiency anaerobic biochemical device for sewage treatment

Abstract

The invention belongs to the field of environmental protection, and in particular relates to a high-efficiency anaerobic biochemical device for sewage treatment. The high-efficiency anaerobic biochemical device consists of three parts: an anaerobic bacteria biochemical reaction container, a vibration excitation system and a reflux system. The present invention uses the vibration of a certain frequency generated by the vibration excitation system to promote the rapid removal of gas in the bacterial reaction process, increase the contact area between bacteria and sewage and improve the anaerobic growth environment of bacteria, and remove the inside of the filler and The bubbles generated on the surface can improve the problem that the traditional reflux reactor cannot remove the bubbles inside the filler. By adding a reflux device for the tube wall, the bubbles on the tube wall are effectively removed, and a perfect anaerobic environment is provided for the anaerobic reaction. By changing the frequency of the vibration, the dead zone inside the reactor can be avoided. Using the backflow device, part of the treated reclaimed water is reapplied to the treatment system, which improves the efficiency of the entire system.

Description

technical field [0001] The invention belongs to the field of environmental protection, and in particular relates to a high-efficiency anaerobic biochemical device for sewage treatment, which can efficiently cultivate anaerobic microorganisms. Background technique [0002] At present, the industry is developing rapidly, and the accompanying pollution is becoming more and more serious. The treatment of many industrial waste water and waste gas has also become a problem. Some factories will dilute the diluted waste water to the national standard and then discharge it. Components, some wastewater is treated by blending combustion and oxidation, and secondary pollution will occur due to insufficient combustion. Most high-concentration wastewater is difficult to completely treat due to its complex composition, such as papermaking, printing and dyeing wastewater treatment decolorization, azo-based The degradation treatment of clusters, most of which are toxic to the wastewater trea...

AI Technical Summary

Problems solved by technology

[0004] The anaerobic biological method mainly relies on the two forms of granular sludge or biofilm carrier. The granular sludge anaerobic bioreactor has high treatment efficiency, but due to the anaerobic process, the internal flow rate of the reactor is low and the internal mass transfer is poor. The treatment efficiency of the reactor is limited by the way of high reflux

For wastewater with high viscosity, channeling problems are also prone to occur during the treatment process

The anaerobic bioreactor in the form of biofilm carrier effectively increases the sludge residence time, on the one hand, it ensures the quality of the effluent, and on the other hand, it is conducive to the start-up of the system. The use of general activated sludge can achieve stable operation, effectively preventing The loss of flocculent sludge, but the blockage of channel flow will also appear in the biofilm carrier type anaerobic reactor, which affects the practical application of anaerobic biotechnology
