摘　　要：农村生活污水及养殖废水导致河道水污染情况愈发严重。以南昌县向塘镇礼坊村农村河道水环境治理为例,研究活性生物炭复合调节剂技术在农村河道污水治理中的应用。通过模拟试验和实地应用对活性生物炭复合剂不同投加量条件下的污水治理研究得出:活性生物炭复合调节剂对富营养化污水中氮、磷元素的去除具有良好的处理效果。模拟试验中,活性生物炭复合调节剂与河道污水的投放质量体积比为1∶150时,净化效果最佳。在第5天时,T3处理对总磷、总氮和氨氮的去除率分别为21.77%、14.32%和23.05%。实地应用中,活性生物炭复合调节剂与河道污水质量体积比为1∶200时,处理效果最佳。在第9天时,M2处理对总磷、总氮和氨氮的去除率分别为53.05%、55.46%和72.84%。由此可知,活性生物炭复合调节剂推荐适宜用量在1∶150~1∶200之间。Rural domestic sewage and aquaculture wastewater leaded to more and more serious river water pollution.the application of active biochar compound regulator technology in the treatment of rural river water environment in Lifang Village,Xiangtang Town,Nanchang County was studied in the paper.Through the simulation test and the field application of the active biochar compound under different dosing conditions of wastewater treatment,it was concluded that the active biochar compound regulator had a good treatment effect on the removal of nitrogen and phosphorus in the eutrophic wastewater.In the simulation test,the purification effect was best when the mass volume ratio of the active biochar compound regulator to the river sewage was 1∶150.On the 5th day,the removal rates of total phosphorus,total nitrogen and ammonia nitrogen in T3 treatment were 21.77%,14.32% and 23.05%,respectively.In the field application,the treatment effect was best when the mass volume ratio of the active biochar compound regulator to the river sewage was 1∶200.On the 9th day,the removal rates of total phosphorus,total nitrogen and ammonia nitrogen in M2 treatment were 53.05%,55.46% and 72.84%,respectively.It could be seen that the recommended dosage of active biochar composite regulator was between 1∶150 and 1∶200.
