Case Introduction of Chaoyang Mountain Pressure Station in Ledu District, Haidong City, Qinghai Province：

Shandong Hechuangzhiyun Environmental Protection Equipment Co., Ltd. is a supplier of water treatment chlorination and dosing system solutions. What you are currently browsing is the Chaoyangshan pressurized station water treatment project in Ledu District, Haidong City, Qinghai Province, which our company participated in the construction of. In this project, our company provided two large sodium hypochlorite generators to the customer, which has solved the water treatment and disinfection needs of the project.

At present, there are generally two commonly used methods for water disinfection: physical methods and chemical methods. Among them, chemical disinfection mainly relies on chlorine, ozone, chlorine dioxide, chloramine, metal ions, halogens, anionic surfactants, and other biological additives. Although there are many ways to disinfect water, the chlorine disinfection method commonly used in the past few years had too many by-products. In recent years, the sodium hypochlorite disinfection method has been mainly promoted. However, due to the difficulty of transporting sodium hypochlorite, a sodium hypochlorite generator is currently used for on-site preparation of sodium hypochlorite disinfectant. The on-site preparation of sodium hypochlorite solution by sodium hypochlorite generator mainly uses water, electricity, and salt to prepare low concentration sodium hypochlorite solution through electrolysis. The on-site preparation system of sodium hypochlorite consists of soft water preparation, salt dissolution tank, sodium hypochlorite generator and supporting power supply, sodium hypochlorite storage and safe hydrogen discharge linkage system, sodium hypochlorite dosing system, and control system. The prepared sodium hypochlorite solution and a small amount of hydrogen enter the dehydrogenation system, and low concentration hydrogen is discharged by blowing fresh air with a fan. The sodium hypochlorite solution enters the storage tank and is waiting to be added. Throughout the entire process, only the addition of raw edible salt requires manual operation, which is very convenient.

The overall equipment can be placed in the same room, but special attention should be paid to the fact that the hydrogen gas produced by electrolysis in the cathode chamber must be connected to the outside through pipelines to avoid explosion incidents when the indoor hydrogen concentration is too high. The overall equipment of the sodium hypochlorite generator is simple, easy to operate, and only requires a single person to manage during operation. Suitable for disinfection of water plants, rural drinking water, sewage, etc.

Overall, on-site preparation of sodium hypochlorite eliminates the transportation process and has lower costs. Generally, the entire equipment investment can be recovered within a few years; The raw materials used are tap water and food grade salt, with a purity of sodium hypochlorite and minimal by-products; Low concentration sodium hypochlorite solution can be stored and is not easily degraded. It is disinfected by the water plant.
