水城河污染状况监测

摘要

Chemical oxygen demand (COD),the dry matter weight (TSS) and pH of water taken from the Shu-icheng river. The results show that the concentration range of COD is 10~1000mg/L, and pH is 5.0~7.0 re-vealing weak acid water. The content of TSS is 0.02~8.75g/L and it has gradually increased from the up-stream to the downstream of river. The results indicate that the Shuicheng river is severely polluted and some Positive measures should be taken to strengthen governance.%为了解六盘水水城河的污染情况，对该河水体的化学需氧量（COD）、干物质重（TSS）及pH进行监测。结果表明：在取样的10个样点当中，COD含量在(10～1000)mg/L范围内波动；pH维持在5.0～7.0之间，水质呈弱酸性；干物质含量为0.02～8.75g/L，且从河流上游到下游TSS总体呈上升趋势。显示了水城河水体有机废水浓度较高，污染较为严重，应采取积极措施加强治理。
