Changchun City 4A molecular sieve plans to put into production 944 million yuan pollution interception project officially started
Changchun Municipal People's Congress Deputy Director Wang Tieming, Deputy Mayor Wang Lu, and Vice Chairman of the CPPCC Li Weidou attended the launching ceremony. Wang Lu announced that Changchun City plans to put into production 980 million yuan, and the 4A molecular sieve water interception project starts.
Changchun City Pollution Interception Project uses dipping method to modify the surface of 4A molecular sieve. By introducing cationic surfactant, the surface of 4A molecular sieve is made to attach quaternary ammonium cations, and forms an 'anion exchange membrane' with the counter ion Br-, thereby More Cr(VI) anions were adsorbed on the modified 4A molecular sieve by ion exchange, and the phase structure and composition of the samples were characterized by X-ray diffraction (XRD) and Fourier transform infrared spectroscopy (FTIR). Studies have shown that the type of surfactant and the structure of the hydrophobic hydrocarbon chain will affect the adsorption capacity of 4A molecular sieve, the hydrocarbon chain length of octadecyltrimethylammonium bromide (OTAB), the dense bilayer formed on the surface of the molecular sieve, The adsorption capacity of Cr(VI) is larger. The pseudo-first-order, pseudo-second-order, Elovich and Bangham kinetic models were used to fit the adsorption data of hexavalent chromium, and the pseudo-first-order kinetic equation was more consistent with the adsorption of octadecyltrimethylammonium bromide modified molecular sieve Behavior.
Chuanhu Sewage Treatment Plant Water Opening Ceremony
Changchun Chuanhu Sewage Treatment Plant is a key pollutant emission reduction project in Changchun's 'Twelfth Five-Year Plan'. It is constructed and operated by Chengkai Water Co., Ltd., a subsidiary of Changchun Chengkai Group. The project covers an area of u200bu200b17.1 hectares. The estimated total investment is 944 million yuan, and the daily processing capacity is 200,000 tons. It undertakes the task of treating urban sewage in an area of u200bu200bnearly 81 square kilometers in the urban area. The construction of the project started in September 2013, and it was put into trial operation on July 1, 2015. By the end of August 2015, the effluent quality had reached the national level A discharge standard.
