Description

TECHNICAL FIELD

[0001] The utility model relates to biological membrane filtration technical field, specifically a kind of biological membrane filtration device for municipal sewage treatment. BACKGROUND

[0002] Municipal sewage is mainly derived from the domestic wastewater of urban residents, including kitchen wastewater, washing wastewater, toilet wastewater, etc., also including urban stormwater runoff and part of industrial wastewater (after pretreatment into municipal sewage pipe network);Municipal sewage treatment is to use physical, chemical and biological methods to remove pollutants in wastewater, so that it meets the national discharge standards or water quality standards that can be reused;

[0003] To ensure the quality of municipal sewage treatment, biological membrane is usually used to filter and treat municipal sewage. In biological membrane method, microorganisms adhere to the surface of solid to form a membrane structure. Compared with activated sludge method, the concentration of microorganisms on the biological membrane can reach a very high level. Due to the certain thickness and structure of the biological membrane, there are different microbial ecological environments inside. When the water quality and quantity of municipal sewage change, the microorganisms in the biological membrane can self-regulate to a certain extent. However, impurities, microbial metabolites and some dissolved substances in wastewater may form dirt or scale on the membrane surface, affecting the filtration performance and service life of the membrane. Although the biological membrane is composed of microorganisms, in some cases, additional drugs may need to be added to control the growth of microorganisms to maintain the stability and filtration effect of the biological membrane. The conventional device cannot effectively add the drugs required by the biological membrane, which may affect the filtration effect of the biological membrane when filtering in different water qualities with different pH values.

[0005] When the water quality indicators such as pH value of raw water are not within the suitable range of biological membrane filtration, the membrane material may be degraded or the microbial activity may be reduced, which may greatly reduce the filtration effect of the biological membrane, and cannot effectively ensure the filtration quality.
