The pollutant concentration and of rural sewage is lower than industrial sewage, and the biodegradability is also better. The village and town sewage treatment products produced by our company have mature water treatment technology and a number of independent intellectual property rights. In addition, our products have regional water environment treatment capacity. Our technology is leading in China.According to the national environmental protection policy, relying on the existing equipment and flexible configuration.We can provide reliable and all-round rural sewage solutions to help customers to improve the rural sewage treatment level, meet the professional needs of customers, realize the "zero discharge" rural sewage treatment requirements, and meet the national environmental protection requirements.

At present, we have sewage treatment projects in many rural region of many provinces across the China. We provide cheaper and more efficient water treatment solutions for engineering companies and water supply and drainage companies. We have gotten good reputation for our employers.

A2/O Technology

Anaerobic-Anoxic-Aerobic Activated Sludge Technology (A2 / O) combines the advantages of an / O and AP / O. It is a series of anaerobic pool, anoxic pool and aerobic pool. This can eliminate nitrogen and phosphorus.However, it is difficult to eliminate nitrogen and phosphorus at the same time in practical operation.In order to meet the effluent requirements, eliminating nitrogen is primary and chemical phosphorus elimination is secondary.In order to simultaneously eliminate nitrogen and phosphorus. There are many improved A2 / O technologies, such as pre denitrification A2 / O process and side flow phosphorus removal A2 / O process.Their treatment effect is stable,and the covered area is small.

MBR Technology

Membranebiore actor (MBR) technology is a new high-efficiency sewage treatment technology that combines high-efficiency membrane separation technology with traditional activated sludge process.The MBR flat membrane module with unique structure is placed in the aeration pool. The water after aerobic aeration and biological treatment is pumped out after being filtered by the pump through the filter membrane.Different from activated sludge process, it does not use sedimentation pool for solid-liquid separation, but uses hollow fiber membrane to replace sedimentation pool, so it has high-efficiency solid-liquid separation performance. At the same time, the characteristics of the membrane are used to preventing the loss of activated sludge with the outflow, form an ultra-high concentration of activated sludge of 8000 ~ 12000mg / L in the biochemical pool, and completely decompose the pollutants. Therefore, the effluent quality is good and stable, and the effluent bacteria, suspended solids and turbidity are close to zero. MBR process has the advantages of high automation, good effluent quality, small floor area, stable effluent quality and low sludge output.
