1. Project introduction (brief introduction of the basic situation of the project)

High-salt industrial wastewater refers to industrial wastewater with a salt content of more than 1%. It usually contains diverse types of organic pollutants with large differences in nature, and the water quality components are complex and diverse. High-salt industrial wastewater has a wide range of sources, including wastewater from industrial production such as pharmaceuticals, petrochemicals, and metallurgy, accounting for 5% of my country's current total industrial wastewater and is still increasing year by year. High-concentration salt has toxic effects on microorganisms, traditional biochemical treatment methods have poor effects, while incineration and other processes have problems such as high energy consumption, serious secondary pollution, and low resource utilization. High-salt industrial wastewater treatment is a difficult and hot spot in wastewater treatment.

2. Cooperation content

(1) Brief introduction of the main related technologies involved (mainly introduce the main technical contents involved in this project and other technologies that need to be supported)

Through micro-electrolysis-catalytic oxidation technology, the technical problems of high toxicity and low biodegradability of high-salt and refractory industrial wastewater have been solved. By strengthening the new biochemical treatment-dynamic membrane high-efficiency separation technology, the technical problems of low biochemical reaction efficiency and poor mud-water separation effect in traditional biochemical treatment have been solved. Through nanofiltration-reverse osmosis treatment and membrane pollution control technology, the technical problems of difficulty in salt separation and difficulty in controlling membrane pollution in salty wastewater have been solved.

(2) Proposed cooperation areas and cooperation objects (mainly describe the areas and recipients of cooperation in the project)

Environmental protection enterprises for industrial wastewater treatment in different provinces across the country.

(3) Proposed cooperation model (briefly introduce the future business model of the project and the cooperation model you hope to carry out)

technology promotion

3. Cooperation cases (if there are demonstrations, applications, etc., available)

4. Environmental impact assessment (such as energy conservation indicators, emission reduction indicators, etc.)

V. Project implementation unit (briefly introduce the main unit undertaking the project and cooperating units)

The School of Environmental Science and Engineering of Tongji University is the earliest environmental education and scientific research unit established by a college among universities in the country. It has the State Key Laboratory of Pollution Control and Resource Utilization Research, the Key Laboratory of the Ministry of Education of the Yangtze River Water Environment, and the National Engineering Research Center for Urban Pollution Control. and other institutions. Environmental Science and Engineering ranked A+ in the fourth round of discipline evaluation and was selected into the national "first-class discipline" construction plan. Environmental engineering is a national key discipline and a key discipline in Shanghai City, which has important influence domestically and internationally. It holds national Class A certificates in environmental engineering design and environmental impact assessment, and enjoys a high reputation in the environmental science and engineering circles. He has undertaken and participated in the work of funded projects such as the "Eleventh Five-Year Plan","Twelfth Five-Year Plan", and "Thirteenth Five-Year Plan", etc., the 863 Plan, the 973 Plan, and the National Key R & D Plan. Relevant achievements have been awarded at the national level in the past five years. There are 5 scientific and technological awards and more than 30 provincial and ministerial awards.
