解放26年来,随着社会主义革命和社会主义建设突飞猛进,我国社会主义给排水事业也得到迅速发展。从水质净化技术的角度来看,中南地区的地面水源大致可分为四类: 一、拥有大量泥砂的高浊水; 二、常年浑浊,但最高含泥量只有几公斤/米~3的河流; 三、水流缓慢,常年水质清澈,但在雨季水质短时较浑的水体, 四、以工业废弃的假定净水为水源。下面按这四类水源,综合介绍在生产实
In the 26 years since the liberation, as the socialist revolution and socialist construction have advanced by leaps and bounds, China’s socialist water supply and drainage business has also developed rapidly. From the point of view of water purification technology, the surface water sources in the South Central region can be roughly divided into four categories: 1. Highly turbid water with a large amount of muddy sand; 2. Rivers that are turbid all year round, but have the highest clay content of only a few kilograms per cubic meter; The water flow is slow, and the water quality is clear throughout the year. However, in the rainy season, when the water quality is relatively short, the water body is more sluggish. According to these four types of water sources below, comprehensive introduction in production
