1. 系统流程：
2. 工作原理：
中水处理系统是将生活污水还原成中水的处理过程。应用过的生活污水被集中在调水池中，由充氧机进行充氧。充氧后的水由提升泵提至生化池，由充氧机进行两级生化。在处理过程中还要对生化过的水进行加药，消毒，搅拌等工序，使其能够达到二次使用的可能。处理过的中水由加压泵打到回用池中，由供水泵供给用户在利用。（主要用为冲厕或绿化用水）

* 手动方式：手动控制两台泵的切换及每台泵的起停。
* 自动方式：自动控制两台泵的切换。
要求：当加压泵出现热保护时自动转换为备用机。
由PLC根据液位自动控制泵的起停（高起低停），泵的起停与提升泵，供水泵，回用池液位联动，防止溢水。
e. 中水供水泵
* 2台（一用一备）380V/3KW 要有手/自动切换
* 手动方式：手动控制两台泵的切换及每台泵的起停。
* 变频恒压供水方式：系统管网压力高于设定时水泵减速运转；低于设定加速运转，一台泵无法满足流量值时另一台泵自动投入运转保证系统压力达到设计要求。由PLC根据液位自动控制泵的起停（高起低停）同时与其它泵联动。系统有超高超低报警及变频器故障自动切换到工频的功能。Electric self stop has been gradually replaced by photoelectric self stop, and photoelectric self stop has developed from two circuit to multiple circuit. Photoelectric and eight way detection double fuses are used to ensure that the train will stop immediately if the train is broken or missing.
Self stop devices are designed for the wrapping roller, head, pressing roller and full barrel, and the housing is equipped with a safety interlock mechanism. At the same time, corresponding colored lights are used for display, which is convenient for operation and disposal.
FA311F high-speed drawing frame combines the advantages of the same type at home and abroad. The main motor adopts a frequency converter. The machine adopts the first system design and equipment selection
1. System process:
2. Working principle:
The reclaimed water treatment system is a treatment process to restore domestic sewage into reclaimed water. The applied domestic sewage is concentrated in the water transfer tank and oxygenated by the oxygenator. The oxygenated water is lifted to the biochemical tank by the lift pump, and the oxygenator conducts two-stage biochemistry. In the process of treatment, biochemical water shall be added, disinfected, stirred and other processes to make it possible for secondary use. The treated reclaimed water is pumped into the reuse pool by the booster pump and supplied to the user by the water supply pump for reuse. (mainly used for toilet flushing or greening)
3. System requirements:
a. Aerator of regulating tank
*2 sets (one for use and one for standby) 380V/1.6KW shall have manual/automatic switching
*Manual mode: manually control the switching of two aerators and the start and stop of each aerator.
*Automatic mode: automatically control the switching of two aerators.
Requirements: when thermal protection occurs to the operating aerator, it will automatically switch to the standby machine.
Aeration is conducted in an intermittent manner, with an interval of half an hour and 15 minutes to ensure the survival of biological bacteria.
b. Biological tank aerator
Two 380V/2.9KW primary biochemical tanks (one for use and one for standby)
Two 380V/1.6KW secondary biochemical tanks (one for use and one for standby)
*Manual mode: manually control the start and stop of the aerator.
*Automatic mode: automatically control the switching of two aerators.
Requirements: when thermal protection occurs to the operating aerator, it will automatically switch to the standby machine.
The aerator operates continuously for 12 hours during the day, and enters into dormant state at night. Aeration lasts for 10 minutes every hour.
c. Lifting pump
*2 sets (one for use and one for standby) 380V/2.2KW shall have manual/automatic switching
*Manual mode: manually control the switching of two pumps and the start and stop of each pump.
*Automatic mode: automatically control the switching of two pumps.
Requirements: when the running pump has thermal protection, it will automatically switch to the standby machine.
PLC According to the liquid level, automatically control the start and stop of the pump (high start and low stop), and the start and stop of the pump are linked with the liquid level of the regulating tank and biochemical tank to prevent overflow.
d. Booster pump
*2 sets (one for use and one for standby) 380V/1.6KW shall have manual/automatic switching
*Manual mode: manually control the switching of two pumps and the start and stop of each pump.
*Automatic mode: automatically control the switching of two pumps.
Requirements: when the booster pump has thermal protection, it will automatically switch to the standby machine.
The PLC automatically controls the start and stop of the pump according to the liquid level (high start and low stop). The start and stop of the pump are linked with the liquid level of the lift pump, water supply pump and recycling pool to prevent water overflow.
e. Reclaimed water supply pump

*2 sets (one for use and one for standby) 380V/3KW shall have manual/automatic switching

*Manual mode: manually control the switching of two pumps and the start and stop of each pump.

*Variable frequency constant pressure water supply mode: when the system pipe network pressure is higher than the set value, the water pump will slow down; If one pump fails to meet the flow value when accelerating operation is lower than the set value, the other pump will automatically put into operation to ensure that the system pressure meets the design requirements. The PLC automatically controls the start and stop of the pump according to the liquid level (high start and low stop) and is linked with other pumps at the same time. The system has the function of ultra-high and ultra-low alarm and automatic switching to power frequency in case of inverter failure.
