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流水槽模具 u型槽模具 电缆槽模具 隔离墩钢模具 护坡砖模具 钢制闸门 螺杆式启闭机 卷扬式启闭机“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.
