What is the valve of the reclaimed water system? To understand this problem, you first need to know what a reclaimed water system is.
The reclaimed water system refers to the water supply system with reclaimed water as the water source. Generally, it includes three subsystems of water delivery, water distribution and treatment. Reclaimed water refers to urban sewage that can be reused within a certain range after being treated to meet the specified water quality standards. It is mainly used for toilet flushing, garden irrigation, vehicle flushing, industrial cooling water, construction engineering and fire water. The reclaimed water system not only alleviates the water crisis, but also is economically feasible.
Reclaimed water treatment and reuse need to be considered in three cases according to municipal conditions:
1. There is a municipal reclaimed water pipe network and a municipal drainage pipe network: the drainage in the community adopts the confluence of sewage and waste (the rainwater system is considered separately), and the drainage is simply treated in the septic tank and then discharged into the municipal sewage pipe network. The water source of the reclaimed water system is municipal reclaimed water.
2. There is no municipal reclaimed water pipe network, but there is a municipal drainage pipe network: the sewage in the community is segregated by sewage. The sewage is discharged into the municipal sewage pipe network after septic treatment; the wastewater is collected through the community wastewater pipeline network to the reclaimed water treatment station in the community, and reused after the treatment reaches the reuse standard. The raw water of the reclaimed water system is the miscellaneous drainage recovered from the community.
3. There is no municipal pipe network: the drainage in the community adopts the confluence of sewage and waste. After being treated in a septic tank, the drained water is collected by the community sewage pipe network to the community sewage treatment station, and reused after the treatment reaches the reuse standard. The raw water of the reclaimed water system is the wastewater recovered in the community.
It can be seen that the reclaimed water treatment is a municipal construction project. The medium in the reclaimed water treatment pipeline is mainly clean water and sewage, which are under normal temperature and low pressure conditions. Therefore, the valves used in the reclaimed water system mainly include:
Soft sealing butterfly valve: handle wafer butterfly valve, worm gear flange butterfly valve, PTFE lined butterfly valve, double eccentric butterfly valve, etc.; the drive form can be manual, worm gear drive, electric, pneumatic.
Gate valve: gray cast iron gate valve, soft-sealed gate valve; manual, electric, etc. can be selected as the driving form.
Knife gate valve: wafer type knife gate valve, flange type knife gate valve, manual, electric, pneumatic, etc.
In addition, the valves and pipeline accessories used in the reclaimed water system include: check valves, globe valves, filters, rubber soft joints, etc.
