        In the future, China's ecological civilization construction and the rapid advancement of new urbanization will generate a huge demand for decentralized sewage treatment in small towns, rural areas and other areas. Kangnuo Environment has rich project experience and engineering practice in decentralized sewage treatment in small towns, and has unique advantages in fine design of technology, fine implementation of construction and fine management of operation, with high degree of automation, remote monitoring, simple operation and management, mature process and stable and reliable operation, high effluent quality standards, reasonable operating costs, etc.

      The domestic sewage treatment system in small towns and rural villages adopts the advantages of MBR technology, combining membrane separation engineering and biological engineering to form a new reaction system, with low investment, fast results, fully automatic control unattended, and providing a full range of services. The equipment system has a significant COD removal effect, good effluent quality, for the characteristics of TN removal and phosphorus removal of domestic sewage, the process design considers the function of MBR nitrogen and phosphorus removal, and minimizes the remaining sludge and treatment costs. Through MBR process treatment, the effluent index reaches the first-class A standard of the "Urban Sewage Treatment Plant Pollutant Discharge Standard", and at the same time plays an active role in realizing the resource and ecology of sewage treatment.

 

Features

◆Efficient solid-liquid separation, stable effluent quality;
◆Low residual sludge production;
◆Small footprint, no need for two sedimentation tanks, integration of process equipment;
◆It can remove ammonia nitrogen and refractory organic matter;
◆It overcomes the disadvantages of easy sludge expansion by traditional activated sludge method;
◆Advanced technology, simple operation management, fully automatic control, no need for people on duty.

 

Scope of application

Townships and rural areas, hotels and restaurants, real estate living quarters, scenic spots, highway service areas, airports, docks, enterprises and other areas where sewage cannot be collected.

 

 

1.Process introduction

Cornerstone absorbs the technology and experience of Germany and Japan, has rich practical projects in decentralized sewage treatment in small towns, adopts intelligent MBR technology and unique biotechnology, has a high degree of automation, can realize remote monitoring, industrial Internet of Things, simple operation and management, mature technology, stable and reliable operation, high effluent quality standards, and reasonable operating costs.

 

 

2.Technical advantages：

MBR technology: It has significant COD emission reduction effect. This process enhances the ammonia nitrogen removal rate and promotes phosphorus removal.
At the same time, the processing volume of remaining sludge in sewage treatment is reduced, which greatly reduces equipment investment and operating costs.
1. Efficient solid-liquid separation, good effluent quality, stable system, COD less than 10mg/L;
2. The remaining sludge production is very small, and the sludge volume is reduced by more than 95%;
3. It occupies a small area, saves more than 50% of land, and integrates process equipment;
4. Can remove ammonia nitrogen and refractory organic pollutants;
5. Overcomes the disadvantage of traditional activated sludge method that is prone to sludge expansion;
6. Advanced technology, simple operation and management, fully automatic control, no need for on-duty personnel, and remote monitoring of the industrial Internet of Things;
7. Energy saving: Compared with traditional sewage treatment technology, it saves 30% energy and has low operating cost of 0.3 yuan-0.5 yuan/t·water;
8. The traditional and backward sewage treatment model that combines micro-power + constructed wetlands has been eliminated.
