摘要:
基于雨水管网实际污染情况，分别向水中输入S2-及SO42-进行模拟实验，通过分析上覆水和底泥中氮、硫等污染物赋存及变化，探究外源硫及其与有机碳源耦合对水体黑臭化的诱导效应。结果表明，输入S2-（1~10 mg/L）后第12 天，各组上覆水的NH3-N、S2-和底泥酸性挥发性硫（AVS）均有积累并出现黑臭，且输入的S2-量越大，积累越多，黑臭越重。S2-耦合有机碳源（TOC为100 mg/L）通过迅速消耗DO显著增加水中S2-和底泥AVS，加速、加重水体黑臭。输入SO42-（50~300 mg/L）后水中未出现黑色物质，但SO≥100 mg/L时会诱导底泥释放NH3-N，引发富营养化并间接导致黑臭。SO耦合有机碳源可诱导间隙水SO积累并转化为S2-向上覆水释放，同时诱导底泥AVS向其他形态硫转化，增加水体返黑返臭隐患。以上结果可为华北某市含有大量有机污染物的管网水排入SO背景值较高水体的返黑返臭防治提供参考。
Abstract:
Based on the actual pollution of the stormwater drainage, S2-and SO42- were input into the water for simulation experiments. Through the occurrence and change of nitrogen, sulfur and other pollutants in the overlying water and sediment, the induced effect of exogenous sulfur and its coupling with organic carbon on blackening and odorization of river was explored. The results showed that the NH3-N, S2- in the overlying water and AVS in the sediment of each group accumulated and appeared black and odorous on the 12 d after the input of S2- (1-10 mg/L). And the higher the dosage, the more accumulation and the heavier the black and odorous. S2- coupling organic carbon (TOC=100 mg/L) significantly increased S2- in the overlying water and AVS in the sediment by rapidly consuming DO, accelerating and aggravating the black and odorous. After SO42- (50-300 mg/L) was input, there was no black matter in the water, but when it was greater than or equal to 100 mg/L, it would induce the sediment to release NH3-N, cause eutrophication and indirectly lead to black and odorous. The SO42- coupling organic carbon could induce the accumulation of SO42- in interstitial water and convert it into S2- to release to the overlying water. In addition, it could induce the conversion of AVS in sediment to other forms of sulfur, and increased the hidden danger of repeated black and odorous. The above results can provide a reference for the prevention and control of repeated black and odorous, when the stormwater drainage water containing a large amount of organic pollutants discharged into the river with a high background value of SO42-.
