近年来成都一些部队和地方医院都采用了同步双虹吸自动加氯装置。这种装置是根据虹吸原理设计的,其构造和原理见简图1,当定量池污水水面升到高水位,即与辅助虹吸管管口平时,污水先在辅助虹吸管内流动,将虹吸管及加氯虹吸管内空气抽掉使其形成真空,产生同步双虹吸,使氯液与污水混合进入消毒接触池,当定量池水面下降到低水位时,空气先进入空气破坏管,使虹吸管和加氯虹吸管内
In recent years, some troops and local hospitals in Chengdu have used synchronized syphon automatic chlorination devices. This device is designed according to the principle of siphon. Its structure and principle are shown in the schematic diagram 1. When the surface of the effluent water in the quantitative pond rises to a high water level, that is, when it is in contact with the auxiliary siphon nozzle, the sewage first flows in the auxiliary siphon tube, and the siphon tube and chlorination are flowed. The air in the siphon tube is evacuated to form a vacuum, and a synchronous double siphon is generated, so that the chlorine liquid and the sewage are mixed into the disinfection contact pool. When the water level of the quantitative pond drops to a low water level, the air enters the air destruction tube first, so that the siphon tube and the chlorine siphon tube
