过去我厂生产用水是由江边用泵抽送到一个天然的贮水池预沉,平均浊度一般达500mg/L,然后自流到二级泵站直接送往生产用户,由于这种水没有经过净化,致使管道堵塞,积垢,尤为严重的是管路滋生的水生物,如小贝壳类等软体动物,堵塞管道更加严重,使过水断面减小,水头损失增高,输水能力降低,因此在用户供水主管道上安 In the past, the production water of our plant was pumped by the riverside to a natural storage tank pre-sinking. The average turbidity was generally 500mg/L, and then it was self-flowing to the secondary pumping station and sent directly to the production user. This water was not purified. , resulting in pipeline plugging, fouling, especially serious aquatic organisms that the pipeline is breeding, such as mollusks such as small shellfish, plugging the pipeline is more serious, so that the cross section of the water is reduced, head loss increases, the ability to transport water is reduced. User water supply main pipeline safety
