Sewage treatment in tonghua reservoir
1. overview of integrated sewage treatment construction.
Tonghua huinan reservoir integrated rural sewage treatment equipment principle of work by using membrane bioreactor (MBR) for wastewater treatment and reuse MBR integration of the sewage treatment equipment, it has all the advantages of membrane bioreactor: at level 1 A, low operating cost, strong impact resistance, less quantity of sludge, high degree of automation, in addition, as the integration of the MBR wastewater treatment equipment, it has small size, ease of integration. It can be used as a small wastewater recycling equipment, and can be used as a larger core processing unit of the sewage treatment plant (station), is currently one of the hotspot in research of wastewater treatment, has broad application prospects.
2. Principle of integrated wastewater treatment.
The working principle of the integrated rural wastewater treatment equipment in huinan county, tonghua city is a new wastewater treatment technology combining membrane separation technology and biological technology. It USES membrane separation equipment to trap the active sludge and macromolecules in the biochemical reaction tank to save the two sinks. Therefore, the concentration of activated sludge is so large that the hydraulic retention time (HRT) and the sludge residence time (SRT) can be controlled separately, and the refractory is continuously reactive and degraded in the reactor. Therefore, membrane bioreactor (MBR) technology has greatly enhanced the function of bioreactor through membrane separation technology. Compared with biological treatment, it is one of the promising new wastewater treatment technologies.
3. Features of integrated sewage treatment equipment.
Tonghua huinan reservoir integrated rural sewage treatment equipment principle of work is a membrane separation technology with activated sludge method combined with the new sewage treatment technology, it has a unique structure of the MBR flat sheet membrane module put in aeration tank, after aerobic aeration and biological treatment of water, resulting from the pump through a membrane filter. MBR wastewater treatment is very different from sewage treatment, and it can be used to replace the secondary sedimentation tank and treatment process. Therefore, the quality of wastewater treatment of environmental protection equipment can not meet the requirements of water reuse. The water from the MBR sewage treatment can be used directly as municipal water or for further processing of various industrial water.
Due to the existence of the MBR membrane greatly the ability of solid-liquid separation, so that the MBR membrane bioreactor, water quality and volume load is greatly, after membrane treatment of water quality is high (more than 1 A), after, after the formation of water quality and biological high quality reclaimed water, can be directly as A new water source. Due to the effect of filtering of the membrane, microorganism was completely trapped in MBR membrane bioreactor, implements the hydraulic retention time and sludge age the complete separation of active sludge, the sludge problem in activated sludge process. The MBR membrane bioreactor for pollutants removal efficiency, nitrification ability is strong, can be simultaneous nitrification, denitrification, and denitrification effect is good, water quality, excess sludge production is low, the equipment is compact, covers an area of less (only process of 1/3-1/2), incremental expansion convenient, high degree of automation, simple operation, etc.
