River Harnessing Technology

River governance is an integral  part of the overall promotion of the ecological construction of modern cities. We will strengthen the construction of water conservancy infrastructure projects and further improve flood control. Drainage and irrigation, irrigation and water conservancy facilities system, from the small river began to improve the industrial wastewater treatment facilities, vigorously carry out sewage treatment and river ecological restoration work, water ecological system construction of good circulation function.


Denitrifying Deep Bed Filter (DDBF)

Combining denitrification with deep bed filtration, denitrifying deep bed  filter is a  treatment unit integrating biological  nitrogen removal and filtration. After the secondary sedimentation tank discharges the effluent, the model can be integrated with other treatment units perfectly, with the functions of nitrogen removal, phosphorus removal, and removal of suspended solids, etc.

Denitrification deep bed filter is especially suitable for the upgrading and reconstruction of municipal wastewater treatment plant, such as upgrading from the Grade B of Level I to Grade A of Level I, or from Grade A of Level I to IV Category of surface water.

                           

Moving Bed Biofilm Reactor Technology (MBBR)

Moving Bed Biofilm Reactor is biological fluidized bed technology based on special structure carrier. The technology combines biofilm and activated sludge process in the same biological treatment unit to improve the treatment effect of the reactor pool, and to enhance the impact resistance of the system.


Dynamic Quicksand Filter

Dynamic quicksand filter is high efficiency filter which integrates coagulation, clarification and filtration. With many technological advantages, it could be widely used in tertiary advanced treatment areas of drinking water, industrial water and municipal wastewater.



Sftp Feed Composite Bioreactor (SFCBR)

Sftp Feed Composite Bioreactor is the improvement and innovation based on traditional A/O technology, to achieve overall pushing flow and partial thorough mixing method in biological dynamic reaction. It has the flexible combination of activated sludge and biofilm process so as to greatly intensify the capacity of decarbonization, nitrification and denitrification.

      

Dissolved Air Flotation and Filtration Technology (DAFF)

Dissolved Air Flotation and Filtration is a new process combining Dissolved Air Flotation (DAF) and Multimedia Filter (MMF). The process has good effluent quality, low turbidity, excellent oil removal effect, integrated design, less head loss and notable lower energy consumption without multiple upgrading, full automation control and unmanned operation.

                                                       

Denitrification and Nitrification Biological Filter Integrated Process (DNF+BAF)

Biological Filter is man processing technology relying on physical filtration of the filler in the sewage (waste) water treatment structures, whereas it attains the pollutant removal from sewage (waste) water with the biochemical action of microbial film attached and growing on the filler.

                     

Advanced Oxidation Processes (AOP)

Advanced Oxidation Processes (hereinafter  as “AOP”) utilize special carrier to adsorb and capture micropollutants in sewage. Meanwhile, the special components and oxidant (ozone and chlorine dioxide) produce large amounts of highly active free radicals (-OH). The refractory organic pollutants in the water will become small molecule substances of low or no toxicity through addition, substitution, electron transfer and chemical bond breaking, or even directly degraded into CO2 and H2O.
