In the process of attracting investment, TEDA firmly establishes the concept of green investment promotion and strengthens project screening for “doing something and not doing anythingâ€. The environmental protection department implemented early intervention and tried to control the entry of pollution items from the source. There was once a private enterprise in Suzhou intends to invest in the development zone to build a plant to develop sulfuric acid and hydrochloric acid purification projects. Although this project has considerable potential profit, due to the existence of certain pollution to the surrounding environment, soil and water sources, the environmental protection department of the development zone Did not hesitate to cast a veto. There are also two companies that were rejected because of the presence of certain radioactive materials in the production process. The staff of the Environmental Protection Bureau of the Development Zone told the reporter that the development zone may lose tens of millions of yuan in investment projects, but only by abandoning these projects can there be more investment projects.
In the interview, the reporter learned that TEDA has always adhered to high standards to build environmental protection infrastructure, ensuring that the capacity of various types of environmental protection facilities is ahead of the needs of industrial construction and urban development. At present, Tianjin TEDA Chemical Industrial Park located in Tianjin Development Zone has used natural gas and has a water purification plant, a 100,000-ton sewage treatment plant daily, and a 1,000-ton electroplating wastewater treatment center. Sewerage, rainwater, heating, gas supply, water supply and other pipe network projects. In addition, the development zone has invested in the construction of a reclaimed water plant, construction of forest parks and ecological water sources, and research and construction of seawater desalination. At present, the desalination demonstration project and industrialization project in the Development Zone have been put into use, reaching 10,000 tons of desalinated water per day; the demonstration project for low-temperature and multi-purpose 10,000-ton desalination industrialization is under intensive development. After the project is completed, Nissan will produce fresh water 2 Ten thousand tons. In addition to the review of new construction projects, the environmental protection department of the Development Zone also implemented environmental protection monitoring on 226 key enterprises in the region, drastically reducing the total amount of pollutants discharged.
