Trace organic pollutants (estrogens, antibiotics, odors, etc.) can be detected in 70%-80% of drinking water sources in China, which are diverse, low in concentration and highly socially sensitive.

The removal rate of such pollutants by more than 90% conventional treatment processes is lower than 10%. Ma Jun, director of the Engineering Center, led the establishment of a theoretical and technical system of oxidation and pollution removal based on intermediate valence manganese.

A composite reagent pre-oxidation technology based on potassium permanganate has been developed to strengthen the pollution removal efficiency of conventional water treatment process economically and efficiently. Under the premise of not changing the existing process flow and not greatly increasing the investment and operating cost,

The remarkable removal of organic micro-pollutants in water has become the main pollution emergency technology in China and the world to strengthen the removal of odors, heavy metals, algae, organic matter and so on. He has obtained 1 US patent and 5 Chinese invention patents.

無動力膜處理濾池反沖洗水技術(shù)

The filter backwash wastewater of waterworks is the main source of waterworks wastewater, accounting for 3%-10% of the daily water volume of waterworks. The water volume is huge. If the recycling and utilization can be realized, the raw water resources and the cost of water transmission project can be saved, and the environmental pollution caused by wastewater discharge can be reduced, which has important social significance and economic value. The engineering Center independently researched and developed the backwash water technology of unpowered ultrafiltration membrane treatment filter, developed decentralized modular backwash water recovery equipment, intelligent control system of the Internet of things and a series of high-efficiency and low-cost advanced treatment technologies of ozone catalytic oxidation, and invented the side-swirl sludge discharge, advection and slanted plate sedimentation tank (patented). Optimization of bidirectional flow inclined plate area, flow channel distribution, flow velocity distribution and other process parameters on the effect of treatment technology, applied in dozens of water supply projects, to solve the international problems of inclined plate inclined pipe sedimentation tank flow state is not good, water quality is not stable.

During the COVID-19 outbreak, the engineering Center actively contributed ideas and suggestions to the fight against the virus at its source, and put forward systematic epidemic prevention suggestions, which were included in major epidemic prevention consulting and research plans and included in the National Technical Guidelines for Water Special Achievements. Invented the ozone water solution of green disinfection technology, nano bubbles to achieve rapid, efficient, safe and inactivated virus, successfully applied to the height of the epidemic outbreak of hubei province a gleam of hospital wastewater disinfection and Harbin COVID - 19 patients treating hospital wastewater disinfection and air disinfection and dalian cold-chain (cold storage) disinfection and suifenhe import container disinfection in the project; Presided over the drafting of the first draft of "Special Report on Water Special Achievements", a technical guide for the epidemic prevention of water plants in China, which was revised and published to provinces, water departments and water plants throughout the country by experts, providing technical guidance for the virus prevention and control of water plants nationwide and making outstanding contributions to the national epidemic prevention. Director Ma Jun was awarded as the National Advanced Worker.
