摘要
草海是滇池的一部分，大量污水排入使草海水体污染日益严重，水体已达重富营养化水平，生态平衡遭受严重破坏，水功能基本丧失。为了保护滇池，必须彻底根治草海，对草海的根治拟采取如下综合成套技术：①改造城市排水系统；②对重点工业废水中的有毒有害污染物进行治理；③城市面源治理；④草海底泥疏挖；⑤污染物现场清除技术；⑥大型水生植物恢复技术；⑦水资源的合理调整。制定了草海及滇池治理的三期规划，实施总投资约３０亿人民币。
Caohai,part of Dianchi in Yunnan Province, is heavily polluted by the discharge of urbanwater water,lost its water body function, and thus threatened the water source of Kuming City. In order to control water pollution in Caohai,comprehensive series of tehcnologies,such as transformation of urban drainage and treatment system, treatment of main undustrial waste water, treatment of area pollution source dredge up of river silt in Caohai,on site clear away technology of polluants, recovery technology of large aquatic plants,and reasonaable management of water resources,are put forward,and short term plan, mid term plan and long term plan for Caohai and Dianchi are formulated. Total investment for these plans is expected to be about 3 billion Yuan RMB.
