| Currently, with the requirements of the industrial distribution planning, new or expanded chemical enterprises must be set up in the chemical industrial park or development zones, and implement the centralized wastewater treatment which facilitate environmental management departments to strengthen supervision Therefore, the chemical enterprises discharging the wastewater only need to carry on the pretreatment to achieve the control standard of the centralism sewage treatment plant, then discharge. However, as the development of chemical products and the production technology, the quantity of chemical wastewater was small, the concentration of organic matter was high, the concentration of organic chemicals was high, the concentration of salts was high, which bring greater difficulties to the treatment.Taking the acrylic acid and the ester wastewater as the object of study in this paper, The wastewater industrialization treatment methods such as burned, wet air oxidation catalyst, aerobic biological treatment etc was introduced, and each processing method with good and bad points was analyzed. The status and progress of the research on the treatment to acrylic acid and the ester wastewater using anaerobic+aerobic biochemistry craft processing was enhanced emphatically on this basis. Taking wastewater treatment project of an acrylic resin production enterprises as an example, through the technology research route as follows:wastewater treatment laboratory-scale experimentâ†'project designâ†'project construction system debuggingâ†'operation, research and practical application on the treatment to the acrylic acid and the ester wastewater using anaerobic +aerobic biochemical process was discussed systematically.Through summarizing and analyzing the problems found in the operation of the project,this study discovered the deficiency of the design and accumulated experience for the acrylic acid and the ester wastewater treatment project. |
