Rain water treatment and reuse system

Abstract

The invention discloses a rain water treatment and reuse system. The rain water treatment and reuse system comprises a safe diversion well, a rain water discard machine well, a buried purifying integrated machine and a rain water reservoir in sequence, a rain water discard machine is arranged in the rain water discard machine well, one end of the rain water discard machine well is connected to a rain water collecting pipe of the safe diversion well, a collecting pipeline is connected to the other end of the rain water discard machine well, the collecting pipeline is connected to a collecting pipe on the upper part of one side of the buried purifying integrated machine, a connecting pipe on the lower part of the other side of the buried purifying integrated machine is connected into the rain water reservoir, a PP water storage module is arranged in the middle of the rain water reservoir, and a mud discharge pump and a reuse pump are separately installed in the rain water reservoir on two sides of the PP water storage module. Rain water is collected and diverted through the safe diversion well, then flows into the rain water discard machine to intercept large particulate suspended matters, then enters the buried purifying integrated machine to treat discarded and initially filtered rain water in depth, then treatment reaches the standard before the rain water enters the reservoirwithout secondary upgrade and purification, so that the system operation is more energy saving, and professional management is not required.

Description

technical field [0001] The invention relates to a rainwater recovery system, in particular to a rainwater treatment and reuse system. Background technique [0002] The existing rainwater recovery process often adopts: rainwater pipe network----abandoned flow---reservoir adjustment and storage (PP module pool or concrete pool)---water pump lifting---purification treatment-clean water pool (PP module pool or concrete pool)---reuse; [0003] The biggest problem of this process is the accumulation of dirt in the reservoir, especially the PP module reservoir. Once the dirt is deposited, it is extremely difficult to clean up, which will deteriorate the water quality in the pool and make it smelly. It cannot be reused and the rainwater collection and reuse will be lost. Function. [0004] Secondly, rainwater recovery is greatly affected by the weather. Water is not used when it rains, and water is needed only when it does not rain. Therefore, the maintenance of water quality is p...

Problems solved by technology

[0003] The biggest problem of this process is the accumulation of dirt in the reservoir, especially the PP module reservoir. Once the dirt is deposited, it is extremely difficult to clean up, which will deteriorate the water quality in the pool and make it smelly. It cannot be reused and the rainwater collection and reuse will be lost. Function

[0004] Secondly, rainwater recovery is greatly affected by the weather. Water is not used when it rains, and water is needed only when it does not rain. Therefore, the maintenance of water quality is particularly important. However, the traditional process does not have any treatment measures before collecting rainwater into the reservoir. The water quality stored in the reservoir deterioration is inevitable

[0005] Third, the system maintenance and operation management is complicated, and it is impossible for the actual use department to be equipped with professionals for management

[0006] Fourth, this process requires secondary upgrading of rainwater to enter purification treatment facilities, and the operation and maintenance costs are high

[0007] The above four reasons have caused most of the domestic rainwater recovery systems to become decorations, resulting in a huge waste of resources
