A kind of microalgae treatment sewage automatic control method

Abstract

The invention relates to an automatic microalgae sewage treatment control method which comprises the following steps: feeding sewage into an adjusting tank of a sewage treatment device, detecting, feeding the sewage which is qualified in detection into a microalgae treatment tank for treatment, feeding the treated sewage into a detection tank for detection, if the sewage is not qualified in the detection, backflowing the sewage inside the detection tank to the adjusting tank for treatment, if the sewage is qualified in detection, backflowing a part of the sewage in the detection tank to the adjusting tank, feeding sewage which is qualified in treatment into a filtering membrane for separation, discharging out clean water, feeding a concentrated algae liquid into a grease induction accumulation tank, feeding the concentrated algae liquid into a spiral bent tube closed type reactor through a pump after the concentrated algae liquid is fed into the grease induction accumulation tank, implementing grease induction, feeding back the concentrated algae liquid to the grease induction accumulation tank, and repeating the operation. The automatic microalgae sewage treatment control method has the advantages that sewage can be well treated, automatic treatment is achieved, and the working intensity of operators is alleviated.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to an automatic control method for treating sewage with microalgae. Background technique [0002] my country's per capita fresh water resources are scarce, and the process of industrialization consumes a lot of water resources. Therefore, sewage treatment technology is particularly important for the protection of water resources in our country. The traditional physical and chemical methods of sewage treatment technology are expensive and easy to cause secondary pollution, and the nitrogen and phosphorus content in the treated sewage is high, which is likely to cause eutrophication of the water body. [0003] Microalgae treatment of sewage can make up for the above shortcomings, with low cost and good treatment effect. However, at present, the automation level of microalgae treatment of sewage is still relatively low, and many key steps still need to be realized manually. When the ...

However, at present, the automation level of microalgae treatment of sewage is still relatively low, and many key steps still need to be realized manually.

When the sewage is being treated, various indicators of the sewage may not be fully up to standard before being discharged into the river; it may also be that the sewage has been treated clean, but the purification process is still going on, resulting in waste of electricity
