Research Content & Progress:
In this project, common key technological problems in the systematic control of water pollution of chemical industrial parks including technologies, equipments and water affair management of wastewater treatment had been addressed to for more than ten years. Primary research contents of this project are as follows:
◆ Association rules between water-quality characteristics of chemical industrial wastewater and the suitability of pretreatment technologies were studied systematically, then series of pretreatment technologies for chemical industrial wastewater with high toxicity, high salinity, high colority, high ammonia-nitrogen and big fluctuation of water quality were developed, and the modular decolorization reactor, and ECQ series of equipments of electrocatalysis flocculation/oxidation /reduction were invented;
◆ Based on the statistic principle of Bayesian dispersion and continuity, the expert system of water affairs management for the charge and the operation of chemical industrial park was developed, whose comprehensive judging reference consisted of the characteristic factor identification of point source pol-lution in chemical industrial park, the dynamic monitoring of key parameters of source strength and the biological utilization of characteristic factor of pollution;
◆ The artificial regulation mechanism of the microorganism community in the biotreatment of the mixed wastewater from chemical industrial park was studied, then the accelerant of microorganism activity and the novel technology for wastewater treatment of multiple circulation cooperating with bioaugmentation were invented, and core equipments for wastewater bioaugmentation treatment were developed, such as the modified biological fluidized bed, the intermittent composite particle bed and the fast installation membrane bioreactor with resistance to contamination.
