c-cbr integrated biological reaction sewage treatment device

Abstract

The invention discloses a C-CBR integrated biological reaction sewage treatment device, which includes a bioreactor, a sedimentation reactor and a water outlet tank. The bioreactor includes an inner layer reactor and an outer layer reactor, and the inner layer reactor is equipped with a The water inlet pipe, the upper part of the inner layer reactor is provided with anoxic reaction zone, the lower part is set with anaerobic reaction zone, the outer layer reactor is an aerobic reaction zone, the upper end of the bioreactor is provided with a jet and a water pump, the jet is connected with the water pump, and the water pump is connected with the The inner layer reactor and the outer layer reactor are respectively connected through water pipe I, and the ejector and the outer layer reactor are connected through water pipe II. The sedimentation reactor includes a sedimentation tank and a mud discharge pipe. The mud discharge pipe is set at the bottom of the sedimentation tank and the bottom of the outlet With outlet pipe. The present invention realizes the organic unification of nitrifying liquid backflow, jet oxygenation and hydraulic agitation through the combination of water pump and jet device, saves traditional aeration equipment and stirring equipment, saves energy consumption, and realizes anoxic-anaerobic-aerobic Continuous circulation, high processing efficiency.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a C-CBR integrated biological reaction sewage treatment device. Background technique [0002] C-CBR integrated biological reaction sewage treatment process refers to the sewage treatment process that completes multiple reactions in the same reactor and realizes multiple functions through the deployment of time or space. At present, more and more integrated processes (such as integrated oxidation ditch process, SBR process, IBR process, integrated membrane bioreactor, multi-point alternate water inlet six-box integration process, multi-point alternate water inlet five-box integration process) process, etc.) are applied to wastewater treatment in rural areas, towns, communities, and factories, but for time-series monomer integration processes, such as SBR process and IBR process, only intermittent biochemical reactions can be performed, and the volume utilization rate is l...

Problems solved by technology

At present, more and more integrated processes (such as integrated oxidation ditch process, SBR process, IBR process, integrated membrane bioreactor, multi-point alternate water inlet six-box integration process, multi-point alternate water inlet five-box integration process) process, etc.) are applied to wastewater treatment in rural areas, towns, communities, and factories, but for time-series monomer integration processes, such as SBR process and IBR process, only intermittent biochemical reactions can be performed, and the volume utilization rate is low; for time-series Combined and integrated processes, such as the D-type integrated oxidation ditch process, the combined operation and control of multiple monomer processes is cumbersome and highly dependent on automation. If the automation control module PLC fails, it needs to switch to manual mode, and manual control The labor intensity is relatively high; for the space sequential integrated process, such as the five-box integrated process and the six-box integrated process, the structure of this type of process is relatively complicated, and at the same time, the requirements for automation are high, and the operation and management are difficult; the traditional integrated process is A lot of equipment is required, including mixing equipment, aeration equipment, water pumps, three-phase separators, etc., which require high investment and high energy consumption
