STM ultra-membrane wastewater treatment process flow

Abstract

The invention discloses an STM ultra-membrane wastewater treatment process flow. The treatment process flow comprises the following steps: A, putting wastewater into a flocculation basin for flocculation treatment; B, putting the flocculated wastewater into an anaerobic tank for anaerobic treatment; and C, putting the wastewater subjected to anaerobic treatment into a biological contact oxidation pond for aerobic treatment. According to the invention, the wastewater is firstly subjected to flocculation treatment, so that granular impurities in the wastewater can be flocculated and precipitated, then the wastewater is sequentially subjected to anaerobic and aerobic treatment, anaerobic and aerobic microorganisms in the wastewater can be further removed, and then the wastewater is subjected to acid-base neutralization treatment and disinfection treatment. The pH value of wastewater can be ensured to tend to be neutral, various germs in the wastewater can be killed, finally, the wastewater is subjected to multiple filtration treatment, the germs and various tiny impurities in the wastewater can be effectively filtered, and the filtered wastewater is subjected to high-temperature sterilization treatment, so that the sanitation of a water body is further ensured, and the wastewater treatment effect is effectively improved.

Description

technical field [0001] The invention relates to the technical field of wastewater treatment, in particular to an STM supermembrane wastewater treatment process flow. Background technique [0002] Wastewater refers to the general term for the water discharged during residents' activities and runoff rainwater. It includes domestic sewage, industrial wastewater, and other useless water such as primary rainwater that flows into drainage pipes and channels. After pollution, it is difficult to purify water that does not meet a certain standard. Industrial wastewater flows directly into channels, rivers, and lakes to pollute surface water. If the toxicity is high, it will lead to the death or even extinction of aquatic animals and plants. Industrial wastewater may also seep into groundwater and pollute groundwater. ; If the surrounding residents use polluted surface water or groundwater as domestic water, it will endanger their health and cause death in severe cases. Industrial was...

After pollution, it is difficult to purify water that does not meet a certain standard. Industrial wastewater flows directly into channels, rivers, and lakes to pollute surface water. If the toxicity is high, it will lead to the death or even extinction of aquatic animals and plants. Industrial wastewater may also seep into groundwater and pollute groundwater. ; If the surrounding residents use polluted surface water or groundwater as domestic water, it will endanger their health and cause death in severe cases, and industrial wastewater will seep into the soil, causing soil pollution

Affect the growth of microorganisms in plants and soil. Some industrial wastewater also has an unpleasant stench, polluting the air, and the toxic and harmful substances in industrial wastewater will be ingested and absorbed by plants and remain in the body, and then reach the human body through the food chain. Harmful to the human body, STM ultra-membrane will produce a large amount of wastewater in the production process, but when the existing technology treats the wastewater generated by STM ultra-membrane, it simply sends the wastewater into the filter box and uses several filters to clean it. For filtration treatment, since STM super membrane wastewater contains many germs and impurities, general filter filtration cannot effectively treat it, which will easily lead to incomplete treatment of STM super membrane wastewater, resulting in the phenomenon of polluting the surrounding environment, which does not meet the national energy conservation requirements. The demand for emission reduction is also not conducive to the sustainable development of resources. Therefore, we propose a STM ultra-membrane wastewater treatment process
