| 摘 要： | 采用混凝气浮-SBR-CRI组合工艺处理合肥循环经济示范园内的农药废水,结果表明:混凝气浮作为预处理措施,能够有效去除悬浮物和部分有机物;在生化池中添加大粪,提高了废水的可生化性,补充了碳源,使CODCr、BOD5、NH3-N和TP的去除率分别在80%、90%、70%、90%以上;CRI作为深度处理工艺,进一步降低废水毒性,确保系统出水达标排放。中试研究证明该组合工艺处理低浓度农药废水经济可行。 |

| Abstract: | A combined technology of coagulation air flotation-SBR-CRI was used to treat low concentration pesticide wastewater from Hefei Circular Economy Demonstration Park.The results showed that: in the pretreatment stage,suspended solids and part of organics could be effectively removed by coagulation air flotation process;adding human excrement into the SBR biochemical pool,the carbon source was supplemented and the biodegradability of the wastewater was improved,the removal rates of CODCr,BOD5,NH3-N and TP were above 80%,90%,70% and 90% respectively;in the CRI advanced treatment stage,the toxicity of the pesticide wastewater was further reduced and the effluent water quality could meet the discharge standard.The results of the pilot scale test showed that,coagulation air flotation-SBR-CRI combined technology was economical and feasible for low concentration pesticide wastewater treatment. |
