摘要:
为减缓猪场废水对水体的污染,在常熟市某小型养猪场排污塘内进行空心莲子草(水花生)对养殖废水的阻隔作用研究。试验自排污口40 m长的空心莲子草截污带内设置6个监测点,监测空心莲子草覆盖与清除后的水体化学需氧量(COD)、氨态氮(NH+4-N)、总氮(TN)、总磷(TP)及浊度,并分析底泥TN、TP含量。结果表明,水体质量随空心莲子草截污带延长而改善,生物阻隔为污染物去除的主要机制。污水经20 m截污带处理后,其 COD、NH+4-N、TN、TP、浊度较排污口分别下降了801%、933%、838%、694%、631%,且与30 m处的阻隔效果相当;同时,20 m处底泥中TN、TP含量较排污口 0~2 m处底泥分别降低550%、689%。因此,20 m长的空心莲子草截污带能有效控制猪场排污物的扩散,并将其截留在排污口附近的底泥中。
Abstract:
In order to slow down the water pollution from piggery sewage, an experiment was set to study bio-interception of Alternanthera philoxeroides (APG) to pollutants in a piggery sewage pond of Changshu. Six monitoring points were set up from the outfall in barrier strip which was 40 m long and covered with APG. Before and after removal of APG, water was collected and analyzed for chemical oxygen demands(COD), ammonia nitrogen(NH+4-N), total nitrogen(TN), total phosphorus(TP) and turbidity. Sediment was also analyzed for TN and TP contents. The results showed that the water quality was greatly improved with the extension of the barrier zone. Bio-interception was the main mechanism of pollutant removal. Compared with water near the outlet, COD, NH+4-N,TN,TP and turbidity had a decline of 801%, 933%, 838%, 694% and 631% with the treatment from barrier strip which was 20 m long, respectively. And the barrier effect was equal to that of 30 m. However, the contents of TN and TP in the sediment of 20 m away from the outlet decreased 550% and 689% compared with those in the sediment of 0-2 m away from the outlet. Therefore, barrier strip which is 20 m long and covered with APG can control the emission of pollutants which from piggery wastewater effectively, and intercept them to the sediments near the outlet.
