前言我国东北地区有丰富的地面水源,为工农业生产的发展和人民生活提供了良好的自然条件。然而,由于这个地区的气候条件,冬季封冰期长,水质具有低温低浊的外观特点,较难处理。而人们对它的认识又不完全,致使这个地区的不少自来水厂的上水合格率,每年有近5个月的时间处于低值,给生产和人民生活带来不少影响与损失。为此,东北三省给排水专业会议和黑龙江省科技工作会议决定:由哈尔滨市自来水公司,哈尔滨建筑工程学院、哈尔滨城建局研究所,吉林给排水勘察设计院共同组成低温低浊水处理试验研究组,进行此项工作。遵照毛主席教育为无产阶级政治服务,教育与生产劳动相
Preface China’s northeast region is rich in surface water sources, providing good natural conditions for the development of industrial and agricultural production and people’s lives. However, due to the climatic conditions in this area and the long ice-sealing period in the region, the appearance of water quality with low temperature and low turbidity is difficult to handle. However, people’s understanding of it is incomplete. As a result, the qualification rate for many waterworks in the area is low for nearly five months each year, which brings a lot of influence and loss to production and people’s lives. To this end, the Northeast China Water Supply and Drainage Professional Conference and the Heilongjiang Science and Technology Work Conference decided that Harbin Water Supply Company, Harbin Institute of Civil Engineering and Technology, Harbin Urban Construction Bureau Research Institute, and Jilin Water Supply and Drainage Survey and Design Institute should jointly constitute a low temperature and low turbidity water treatment experimental group. , to do this work. Follow Chairman Mao’s education to serve proletarian politics, education and production labor.
