Water resource recycling system and control method

Abstract

The water resource recycling system comprises a control system, a reservoir, a water supply pump, a water treatment system and a clean water tank, the reservoir, the water supply pump, the water treatment system and the clean water tank are communicated in sequence, the clean water tank is communicated with a useful water pump and is sequentially communicated with a water supplementing valve and a water supplementing end, and the upper portion of the clean water tank is communicated with an overflow pipe; the clean water tank is provided with a liquid level device and an alarm, the clean water tank is communicated with a flow abandoning valve, and the water supply pump, the water using pump, the water supplementing valve, the flow abandoning valve, the liquid level device and the alarm are all in signal connection with the control system. When it is monitored that water is at the first water level during raining, an alarm is given, a water pump for supplying water to the outside of the clean water tank is stopped, and an electromagnetic valve is opened to collect rainwater; when the water is monitored to be at the second water level, opening a water replenishing valve, and closing the water replenishing valve when the water is replenished to a fourth water level; when the fifth water level is monitored, the water flows out of the overflow pipe, an alarm is given, the discarding valve is opened, and the discarding valve is stopped when the fourth water level is reached. The system has the advantages of rainwater recycling, environmental protection, intelligent and automatic water supply and water use and the like.

Description

technical field [0001] The invention relates to the technical field of water resource recycling control, in particular to a water resource recycling system and a control method. Background technique [0002] At present, there is a shortage of water resources in some areas such as the north in my country, and many industries need to use a large amount of water. In some industries that do not require high water quality, such as the construction industry, if a large amount of tap water is used, it will increase energy consumption. When building construction, large amounts of water are usually used and the construction period is long. When the rainy season is encountered, rainwater cannot be used for construction sites such as scouring the ground, which do not require high water quality but require a large amount of water. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to solve at least one of the technical problems existing in the prior art, and fo...

Problems solved by technology

[0002] At present, my country is short of water resources in some areas such as the north, and many industries need to use a lot of water. In some industries that do not require high water quality, such as the construction industry, if a large amount of tap water is used, energy consumption will increase.

During building construction, a large amount of water is usually used and the construction period is long
