苏州市横山水厂两座3万米~3/日机械加速澄清池是1977年建成投产的。近年来通过对它的技术改造,产水量已超过设计能力一倍,1983年高峰供水时,两座澄清池出水量达12.2万米~3/日,出水浊度为5度左右。水源特点是低浊度,年平均为79度,最低月仅为26度,最高月为142度;年平均色度为26度,pH 值为7.4,耗氧量为2.10毫克/升。
Two 30,000-meter to 3-day mechanical accelerated clarifiers at the Hengshan Water Plant in Suzhou City were completed and put into production in 1977. In recent years, through its technological transformation, the water production capacity has exceeded twice the design capacity. At the peak water supply in 1983, the water output from the two clarifiers reached 122,000 meters to 3 days per day, and the effluent turbidity was about 5 degrees. The water source is characterized by low turbidity, with an annual average of 79 degrees. The lowest month is only 26 degrees and the highest month is 142 degrees. The average annual color is 26 degrees, the pH value is 7.4, and the oxygen consumption is 2.10 milligrams per liter.
