摘要
介绍了交互式物化/生化反应器处理城市污水的工艺流程和特点。研究了交互式物化/生化反应器中试系统在低温低进水浓度(水温13-17℃,平均CODCr为144mg/L)和自然不接种的情况下,利用生态絮凝剂聚硅硫酸铁和助凝剂聚丙烯酸进行活性污泥培养和成长的过程规律,并在自然状态下(水温17-23℃,平均CODCr为117 mg/L) 对生成的活性污泥进行驯化。
The process and characteristics of Interactive Physicochemical-Biochemical Reactor (IPBR) were introduced. At lower temperature and concentration (temperature at 13-17℃, average CODCr 144 mg/L), activated sludge was successfully cultivated naturally in IPBR pilot test system. Ecological coagulant poly ferric silicate sulfate and coagulant aid poly acrylic was applied. After cultivation, the activated sludge was successfully acclimated naturally(temperature at 17-23℃, average CODCr 117 mg/L).
