| 中文摘要: |
| 为了解淡水混养鱼塘养殖水质对周围水环境的影响，于2012 年5~10月对广西武鸣县淡水鱼类主养区的3口池塘进行水质监测。测定养殖周期内TN、TP、高锰酸钾指数(CODMn)、NH4+-N、DO、NO2--N含量，分别以地表水环境功能标准和淡水养殖废水排放标准对养殖池塘以及排水口水质进行综合水质标识指数评价。结果表明，武鸣县混养鱼塘养殖周期内池塘水质地表水环境芋类水达标率为72.1%，出水口水质达到我国淡水池塘养殖水排放要求中的一级标准。说明武鸣县淡水混养鱼塘水环境综合水质基本达到地表水环境功能区要求，池塘废水排放符合标准。 |

| In order to understand the effects of freshwater polyculture aquaculture ponds water quality on surrounding environment,
three ponds were selected in the Wuming country, which were Guangxi province's large freshwater fish center of the lead breeding. The research routinely monitored contents of TN, TP, chemical oxygen demand (CODMn), NH4+-N, DO, NO2--N concentrations in the water. With the Standards of 《Environmental Quality Standards for Surface of China》and 《Requirement for Water Discharge from Freshwater Aquaculture Pond》to evaluate the comprehensive water quality of aquaculture ponds and outfalls. The results indicated that the water quality of freshwater polyculture fish ponds in Wuming's country met the standard rate of Grade Ⅲ was 72.1%; The comprehensive water quality identification index of outfall was up to the standard Grade I of 《Requirement for Water Discharge from Freshwater Aquaculture Pond》. The study revealed that the pond culture water in Wuming country met the requirements of water environment function basically,
and the exclude wastewater of pond without pollution to the surrounding environment. |
