摘要
针对合肥市循环经济园园区内混合农药污水浓度较高、可生化性较差等特点,采用混凝-SBR物化处理和生化处理相结合的工艺处理典型化工园区混合型农药废水,并进行中试研究。首先考察了混凝剂和助凝剂投加量对废水物化处理效果的影响,并得到最佳药剂投加量;然后验证了此工艺对化工园区混合农药废水的处理效果,最后进行了此工艺抗冲击能力的实验。结果表明,此物化、生化相结合的处理工艺对化工园区混合农药废水处理效果良好,COD,氨氮的去处率达80%以上,说明该工艺可以在一定程度上处理此类废水。
The feature of mixed industrial wastewater in Hefei circular economy park is high concentration and bad biodegradability, using the technology of coagulation-SBR to process typical mixed pesticide wastewater in chemical industrial park and do pilot scale test.First inspecting the coagulant and coagulant dosage on the physic-chemical wastewater treatment effect, and get the best pharmaceutical dosage; then verify the process on the chemical industry park mixed pesticide wastewater treatment effect, and finally carried out the process impact the ability of the experimental. The result shows that the treatment effect of this technology to wastewater in chemical industry park is well, the removal rate of COD, ammonia is more than 80 %, so to some extent the process can treat such wastewater.
