2. 减少用水量：目前，我国用水，一方面水资源紧张，另一方面与工业化国家相比浪费非常严重，我国许多产品单位用水量大得多，不仅造成水资源浪费，而且造成水污染一个重要原因是通过企业技术改造，促进清洁生产，降低单位水产品消耗，提高水利用率再次，都是在实践中被证明行之有效建立城市污水处理：为了控制水污染，发展，工业企业也必须积极解决水污染问题，特别是有毒污染物排放必须单独处理或预处理与工业布局相适应，进行调整对城市布局和城市污水管网建设和完善，逐步实现城市污水集中处理、城市污水和工业废水处理并举。

Water pollution affects the plants and oris living in these water bodies. In almost all cases, this impact not only cses damage to individual species and populations, but also to natal biological communities, if pollutants are directly or indirectly discharged into the water body without pper treatment, water pollution will occ.
