- Abstract:
- Chlorination and dosing system is an important supporting facility for the purification process of urban water supply plants. It provides chemical storage, preparation, dosing and other services for urban water supply plant. With the increase in the number of urban drinking water sources, the water quality of different water sources is different, and the risk of sudden contamination increases when source water is transported by long-distance pipelines. To cope with the problem, the process of water supply plant is getting longer, and the chemical dosing is also diverse. Therefore, higher requirements are imposed on the design of chlorination and dosing system in water supply plants. In a large water supply plant in north China, the chemicals of chlorination and dosing system includes ferric chloride, basic aluminum chloride, sulfuric acid, sodium hydroxide, sodium hypochlorite, ammonia and other agents, indicating that it is a typical multi-agent compound chlorination and dosing system. Considering the different chemical characteristics of the agents, protective measures such as anti-corrosion, anti-splash, ventilation and leaked ammonia absorption were adopted in the design according to the different characteristics of the agents, which effectively reduced the risk of the use of agents and improved the convenience of the operation.
