Problems solved by technology

One disadvantage of the ABR reactor is that the quality of the effluent from the system is poor, and it usually requires subsequent treatment to meet the discharge standards.
However, in the ABR-SBR combined process, the effluent of the ABR reactor is pumped into the sump through the pump, the effluent of the sump is pumped into the SBR reaction tank or the biological contact oxidation tank through the pump, and the effluent of the SBR reaction tank or the biological contact oxidation tank is pumped into the sump through the pump. Coagulation sedimentation sand filter, so the amount of pumps and water pipes is large, the structure of the system is complicated, the floor area is large, and the energy consumption of the system is large during operation, which greatly increases the cost of the system

Abstract

The present invention relates to one kind of integral high concentration waste water processing apparatus. The apparatus has aerobic baffle plate reactor, water collecting settling tank, aerobic reaction tank or biological contact oxidizing tank and settling tank connected via vertical baffle plates. The unique separating structure and the plug flow mode make each reactor capable of domesticating and culturing microbe colony adaptive to the water quality and environment condition. The present invention is favorable to utilizing the activity of the anaerobic bacteria colony, raising the processing effect and stability of the system and simplifying the system structure. The present invention has small coverage area, low system cost, low power consumption and no frost crack of pipeline.

Description

Technical field: [0001] The invention relates to a waste water treatment device, in particular to an integrated waste water treatment device, which is suitable for the treatment of high-concentration organic waste water. Background technique: [0002] At present, in the treatment of high-concentration organic wastewater, it is difficult to directly use anaerobic or aerobic biological treatment processes to achieve ideal results, and the A / O process that uses the hydrolysis and acidification section of the anaerobic process as the front-end treatment has attracted more and more attention. . With the deepening of the research on the mechanism of anaerobic digestion and the rapid development of various high-efficiency anaerobic reactors, the anaerobic biological treatment technology of wastewater has become one of the core technologies of resource and environmental protection. UASB is a high-efficiency anaerobic reactor developed by Lettinga et al. of Wageningen Agricultural U...
