我国污染严重,又是一个人均拥有水资源贫乏的国家,环境保护、水污染防治、依据当地水资源及经济情况合理进行污废水利用已成当务之急。建设中水系统,不但可以节约用水,并且可以一定程度防止水体污染。目前中水系统成本过高,主要原因是设备的处理能力得不到充分利用,合理设计中水系统是节省资源和能源的关键。这里针对不同功能的建筑可采用不同的节水对策和技术:在住宅和办公楼中应改进马桶的冲洗方式,减少冲洗水量;在宾馆、饭店中,应考虑沐浴污水的处理及回用。 It is a top priority for our country to seriously pollute the water and to utilize it according to the local water resources and economic conditions because of the serious pollution in our country and the fact that every country has a country that lacks water resources. Construction of the water system, not only can save water, and to a certain extent, prevent water pollution. At present, the cost of the water system is too high, mainly due to the insufficient utilization of equipment and the rational design of the water system is the key to saving resources and energy. Here for different functions of the building can use different water-saving measures and technologies: In residential and office buildings should be improved toilet flushing method to reduce the amount of flushing water; in hotels, restaurants, should consider bathing sewage treatment and reuse.
