初步发展阶段
Preliminary development stage
1949年建国以后,中国的污水处理行业经历了初步的发展,主要集中于脏乱差的老城区污水收集管道建设,污水截留,城市黑臭河湖整治改造等。著名的综合整治工程有北京龙须沟、天津赤龙河和四通河、上海肇家滨、南京秦淮河、武汉黄孝河等。与此同时在此期间中国还建设或开始建设了一批一级污水处理厂。如北京高碑店一级污水处理厂,日处理规模可达40万立方米。
Since 1949, China's sewage treatment industry has experienced initial development, mainly focusing on the dirty old urban sewage collection pipeline construction, sewage interception, urban black odor River and lake renovation and so on. Famous comprehensive renovation projects include Beijing Longxugou, Tianjin Chilong River and Sitong River, Shanghai zhaojiabin, Nanjing Qinhuai River, Wuhan Huangxiao River, etc. At the same time, China has also built or started to build a number of first-class sewage treatment plants during this period. For example, Beijing Gaobeidian Wastewater Treatment Plant has a daily treatment capacity of 400000 cubic meters.
但是于此同时国内的污水处理技术依旧停留在较初级的阶段,多利用水体的自净或者较初级的水处理方式,没有把污水处理作为城市发展的一项重要内容,在技术上也没有较大的发展,仍处在相对比较落后的状况下。
However, at the same time, the domestic sewage treatment technology still stays in the relatively primary stage, making more use of the self purification of water body or the primary water treatment method, and does not take sewage treatment as an important part of urban development, and has not made great progress in technology, and is still in a relatively backward situation.
污水土地利用改造阶段
Sewage land use transformation stage
从十九世纪六十年代开始,由于工农业的进一步发展污水农业灌溉的观念得到发展,此时污水污染程度较低许多缺水地区将污水灌溉利用作为经验进行推广如北京东南郊污水灌溉区、天津武宝宁污水灌溉区等。在1980年直接利用污水灌溉的农田更是达到133.3万公顷。极高的提高了我国农业水资源的利用效率,有效的缓解了当时水资源短缺和污水污染的问题。
Since the 1860s, due to the further development of industry and agriculture, the concept of sewage agricultural irrigation has been developed. At this time, the pollution degree of sewage is relatively low, and many water shortage areas take sewage irrigation as experience to promote, such as the sewage irrigation area in the southeast suburb of Beijing, the sewage irrigation area in wubaoning of Tianjin, etc. In 1980, 1.333 million hectares of farmland were directly irrigated with sewage. It greatly improved the utilization efficiency of agricultural water resources in China, effectively alleviated the problems of water resources shortage and sewage pollution at that time.
1957年,当时的建工部与农业部及卫生等部门把污水灌溉列入了国家科研计划。60年代,有关部门还曾在北京高碑店污水处理厂召开了“亚、非、拉国际污水灌溉研讨会”。鉴于污水灌溉的风险,1972年,国家在石家庄召开的全国污水灌溉会议,提出了“积极慎重”的污灌方针,并制定了污水灌溉暂行水质标准,以应对污水灌溉的风险。
In 1957, the Ministry of construction and construction, the Ministry of agriculture and health and other departments put sewage irrigation into the national scientific research plan. In the 1960s, the relevant departments also held the "Asia Africa Latin America International Symposium on sewage irrigation" at Beijing Gaobeidian sewage treatment plant. In view of the risk of sewage irrigation, the national sewage irrigation conference held in Shijiazhuang in 1972 proposed the "positive and prudent" sewage irrigation policy and formulated the temporary water quality standard for sewage irrigation to deal with the risk of sewage irrigation.
