我国目前有各种规模和性质的小城镇近48000多个,其中建制镇19200多个,吸纳2亿多居民。近几年来,随着乡镇企业的迅速发展和村镇人口的不断集中,小城镇的污水排放量不断增加,绝大多数城镇没有有效的污水处理设施,不仅造成小城镇本身的环境污染,而且成为区域性水环境的重要污染源。在社会生产力高速发展的同时,人们逐渐认识到,水并不是取之不尽用之不竭的资源,水资源紧缺已经成为世界性的问题。根据不完全统计,目前世界上有100多个国家缺水,我国是其中之一。全国300多个大中城市中有180多个缺水,其中50个严重缺水。因此,合理利用资源,有效防止水环境污染已成为亟待解决的问题,笔者认为,要解决这些问题,应从以下几个方面做起:
At present, there are nearly 48,000 small towns of various sizes and nature in our country, of which 19,200 are built-up towns and cities and attract over 200 million inhabitants. In recent years, along with the rapid development of township and village enterprises and continuous concentration of rural population, the discharge of sewage in small towns is constantly increasing. Most towns do not have effective sewage treatment facilities, which not only cause environmental pollution in small towns but also serve as regional Sexual water environment, an important source of pollution. Along with the rapid development of social productivity, people are gradually realizing that water is not an inexhaustible resource, and water scarcity has become a worldwide problem. According to incomplete statistics, there are over 100 countries in the world with water shortages, and our country is one of them. Over 180 large and medium-sized cities across the country have more than 180 water shortages, of which 50 are seriously water-scarce. Therefore, the rational use of resources to effectively prevent water pollution has become an urgent issue, I believe that to solve these problems, we should start from the following aspects:
