STANDARD RAISING TECHNOLOGY OF RURAL DOMESTIC SEWAGE


Rural Domestic Sewage Treatment Equipment

A2O-MBR process
A2O-MBR is a new wastewater treatment process which is composed of biological wastewater treatment technology and membrane separation technology. By using the high-efficiency interception of membrane, microorganisms are completely trapped in the bioreactor, and the hydraulic retention time (HRT) and sludge retention time (SRT) are completely separated, so that the pollutants pretreated in the biochemical stage can be efficiently degraded. The main indexes of the effluent quality reach the surface level class IV.

A2O-TFF process
A2O-TFF is a new efficient rural sewage treatment process, which integrates A2O, SBR, contact oxidation process and tidal biological aerated filter. After the A2O process, the secondary deepening treatment is connected with TFF process to separate the nitrogen and phosphorus removal in the double sludge system, and regulate the return flow of nitrification effluent according to the influent water quality, so as to solve the contradiction between denitrification and phosphorus release by phosphorus removal bacteria. Under the conditions of low sludge production, low backflow energy consumption and short residence time, the 1st class A standard of (GB 18918-2002) fully utilized.

Super Membrane Reactor (SMR system)
Super membrane reactor (SMR) is an efficient wastewater treatment technology. Based on the principle of MBR biofilm reactor, the activated sludge in biochemical reaction tank is intercepted by membrane separation equipment. SMR system not only replaces the secondary sedimentation tank in the traditional sewage treatment process, but also directly obtains stable water quality by solid-liquid separation. It can also maintain a high concentration of microbial biomass in the biological tank. With less excess sludge, it can effectively remove ammonia nitrogen, bacteria and viruses in the effluent are greatly removed. The suspended solids in the water are close to zero, energy consumption is low and the floor area is small. The main indexes of effluent quality reach the surface level V.
