给水预氧化理论与技术

Potassium permanganate and its composite pre-oxidation, potassium permanganate - powder activated carbon combined production results have been included in China's urban water supply industry technology progress development plan,

UNESCO "Urban Water Resources Management" technical guide, national key planning textbooks for colleges and universities. Potassium permanganate and its composite agent pre-oxidation technology has been used in more than 100 water plants and water stations at home and abroad.

Ozone catalytic oxidation technology has been applied to dozens of water treatment projects. At present, ozonation has become the core technology of advanced treatment and resource utilization of wastewater in petrochemical industry, oil refining industry and city

高级氧化组合工艺推广应用

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.

无动力膜处理滤池反冲洗水技术

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.
