济南每天需要排出大量的生活污水(如廚房、理发、打扫廁所等脏水)和工业废水(工厂、矿山排出的脏水),这些脏水往往被认为有毒而不加利用,把大部分的污水和废水都排入小清河,使小清河变成“臭水河”,污染了河道,影响居民的飲水和环境卫生。1955年济南市北园人民公社和西郊人民公社的部分生产队,为了搶救作物,減輕旱情,对污水灌溉农田进行小面积的試驗,效果很好,用污水浇灌的作物生长茁壮,产量比未浇污水的提高50—60%左右,有的高达1—2倍。利用污水灌溉农田对保証郊区农业生产更大跃进,增产更多的蔬菜、粮食,以支援社会主义建设有重大的意义。现将污水使用經驗介紹如下: Jinan daily needs to discharge large amounts of domestic sewage (such as kitchen, barber, dirty toilets and other dirty water) and industrial wastewater (factories, mines discharged dirty water), these dirty water is often considered toxic without utilization, most of the sewage And waste water are discharged into the Xiaoqing River, so that Xiaoqing River into a “smelly river”, polluted the river, affecting residents of drinking water and sanitation. In 1955, part of the production teams of Beiyuan People’s Commune in Jinan City and People’s Communes in the Western Suburb carried out small-scale tests on sewage-irrigated farmland for rescuing crops and alleviating the drought. The crops that were irrigated by sewage were robust and the output was not as strong Sewage pouring increased about 50-60%, and some as high as 1-2 times. The use of sewage to irrigate farmland is of great significance to ensuring a greater leap forward in agricultural production in the suburbs and increasing more vegetables and grain so as to support the socialist construction. The sewage experience is now introduced as follows:
