Autotrophic denitrification is a process of reducing nitrogen to nitrogen gas in an anaerobic or anoxic environment by cultivating specialized denitrifying bacteria and immobilizing microbial carriers to provide an electron donor alone and use nitrate or nitrite as an electron acceptor.

The process utilizes self-developed composite catalysts, combined with micro-nano bubble generators, to innovatively form a fluidized bed ozone advanced oxidation deep treatment process. Compared with the fixed-bed ozone oxidation process, it can further improve the treatment effect and save the cost.

The core of sidestream deep nitrogen and phosphorus removal process is to modify the sludge products of sludge cracking and carbonization process into powder carrier that can be efficiently loaded with microorganisms, and add them to the biochemical system of the sewage plant, to form a biochemical system combining the activated sludge and biofilm methods, with the help of carbon-rich magnetic bio-char with micrometer-sized pores, flow simulation system, precise aeration system, magnetic recovery system, to improve the biochemical efficiency of the whole biochemical system. With the help of carbon rich magnetic biochar with micron-sized pores, flow field simulation system, precise aeration system and magnetic recycling system, the biochemical efficiency of the whole biochemical system can be improved.

The process mainly includes "mechanical dewatering section", "pyrolysis and carbonization section" and "tail gas treatment section". The core part of the pyrolysis and carbonization section utilizes an oxygen-poor and high-temperature environment to promote the pyrolysis and carbonization reaction of sludge and other solid wastes, which greatly reduces the level of carbon emissions.

Aerobic bioremediation is a green, enhanced bioremediation technology that relies on modifying geochemical conditions to stimulate indigenous bacteria that can biodegrade the target pollutants, thereby achieving the purpose of remediation, without the introduction of foreign bacterial strains, and without generating odors or leachate during implementation. Through the combination of gas purification and leachate recycling, the landfill can be stabilized in a short period of time and can be converted into land for municipal landscaping companies or commercial use.

Biofilter in the aeration system, pollutant loading calculations, backwash design and other aspects of the traditional aeration biofilter process optimization combined with the bio-bacterial library, to ensure that the water quality COD compliance rate, reduce the power consumption of tons of water.

Denitrification biofilter can solve the problem of total nitrogen, total phosphorus and SS compliance in the upgrading of municipal wastewater treatment plants, while the optimized aeration system can prevent the filter media from sloughing.

Biotechnology and genetic engineering develop high-efficiency, low-energy-consumption, easy-to-popularize special organisms to solve efficiency problems in areas such as water environment, soil remediation and air pollution.

Advanced oxidation technology is used to improve the B/C ratio of difficult-to-degrade organics and to reduce COD to meet discharge standards in deep upgrading processes for wastewater. We have developed catalysts that can effectively improve the degradation efficiency of COD and micropollutants.
