前言遵照毛主席“教育必须为无产阶级政治服务,必须同生产劳动相结合”的教导,我们走出校门,在黄河中游段进行了黄河高浊度水净化的半生产试验,把斜板斜管沉淀新技术应用于高浊度水的净化。以下是进行半生产性试验的部分内容,从现场设备到试验运行情况及成果的分析,并提出了高浊度水净化构筑物的初步设计数据。虽然试验取得的只是初步成果,但这是我们坚持开门办学,走《五·七》道路的结果,它为中条山有色金属公司及黄河中游段工业发展用水提供了新的途径,也是对把开门办学诬蔑为“实践—实践—实践”等种种奇谈怪论的有力回击。由于我们水平有限,所以在总结的过程中难免出现错误,希读者及时批评帮助。 According to Chairman Mao’s teaching that “education must serve proletarian politics and must be combined with productive labor,” we went out of school and carried out a semi-production test of the high turbidity water purification of the Yellow River in the middle reaches of the Yellow River. The tube sedimentation technology is applied to the purification of highly turbid water. The following are some of the contents of the semi-productive test, from the field equipment to the test operation and results analysis, and put forward preliminary design data for high turbidity water purification structures. Although the test has only achieved preliminary results, this is the result of our persistence in running schools and taking the “May 7th” road. It provides new ways for the industrial development of Zhongtiaoshan Nonferrous Metals Company and the middle reaches of the Yellow River, and it is also Opening the door to school is a powerful counterattack of various strange ideas such as “practice-practice-practice”. Due to our limited level, it is inevitable that mistakes will be made in the process of summing up. The Greek readers will promptly criticize and help.
