Multistage sewage treatment device

Abstract

The invention discloses a multistage sewage treatment device. The multistage sewage treatment device comprises a sewage pool, the right side of the sewage pool is communicated with a first water pumpthrough a water pipe, the right side of the first water pump is communicated with an anaerobic treatment device through the water pipe, the right side of the anaerobic treatment device is communicatedwith a second water pump through the water pipe, the right side of the second water pump is communicated with an aerobic treatment device through the water pipe, the left side of the sewage pool is fixedly connected with a PH detection instrument, the right side of the PH detection instrument is fixedly connected with a detection probe, the right side of the detection probe penetrates through thesewage pool and extends into the sewage pool. The multistage sewage treatment solves the problems that the existing sewage treatment cannot better control the treatment environment of microbe, and thereby the normal reaction of the microbe is influenced, so that the sewage treatment effect is poor through cooperation of a carbon dioxide concentration detection instrument, an oxygen concentrationdetection instruction, an aerator, a breather pipe, a heating plate and a temperature sensor.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a multi-stage sewage treatment device. Background technique [0002] With the rapid development of my country's economy and the continuous improvement of people's living standards, more and more sewage containing various organic compounds is produced, including domestic sewage and industrial sewage. The organic components in it need to consume a large amount of dissolved oxygen in the water during the process of biological oxidation and decomposition, causing the water body to be hypoxic and corrupt, resulting in serious water pollution and environmental pollution. At present, there are many methods of sewage treatment using microbial technology, such as activated sludge method, biofilm method, upflow anaerobic sludge bed method, etc. One of the keys to these technologies is to screen and domesticate microorganisms with high ability to decompose organic matter in sewage ...
