摘要：

In view of the characteristics of polyacrylate wastewater, such as high concentration, hard degradation and single component, a biological treatment method adopting an anaerobic-aerobic reactor based on co-metabolism was studied, focusing on the startup operating of and the performance of the reactor. The results show that the system operating cycle is about 30 d on the basis of increasing the ratio of polyester wastewater. Besides, under the conditions of concentration of chemical oxygen demand (COD) 1 600 mg/L, hydraulic residence time (HRT) of 41.7 h, temperature of (35±3)℃ and concentration of dissolved orygen (DO) 3.5 mg/L, the average removal rate of COD is 95.2%. The main indexes of the final effluent reaches the water pollutant emission standard of textile dyeing and finishing industry. It is also proved that the system has strong load impact resistance.
