Rainwater quality control regulation and storage system and control method

Abstract

The invention relates to a rainwater quality control regulation and storage system, and belongs to the field of water treatment technologies. The rainwater quality control regulation and storage system comprises a rainwater pipeline, a gate valve, an initial rainwater regulation and storage tank and a rainwater utilization regulation and storage tank. The gate valve is arranged on the rainwater pipeline, the initial rainwater regulation and storage tank is connected with the rainwater pipeline by a first branch rainwater pipeline, and a first stop valve is arranged on the first branch rainwater pipeline; the rainwater utilization regulation and storage tank is connected with the rainwater pipeline by a second branch rainwater pipeline, a second stop valve is arranged on the second branch rainwater pipeline, and a first quality sensor and a second quality sensor are arranged on the rainwater pipeline and are positioned on upstream sides of the initial rainwater regulation and storage tank and the rainwater utilization regulation and storage tank. The invention further discloses a control method implemented by the rainwater quality control regulation and storage system. The rainwater quality control regulation and storage system and the control method have the advantages that rainwater can be treated by the initial rainwater regulation and storage tank, so that pollution of the initial rainwater on water can be reduced to a great extent; later clean rainwater can be collected and utilized by the rainwater utilization regulation and storage tank.

Description

technical field [0001] The invention belongs to the technical field of water treatment, and in particular relates to a rainwater quality control regulation and storage system and a control method. Background technique [0002] In the early stage of rainfall, the rainwater contains a large amount of floating matter, suspended matter and many pollutants. The water quality is poor, and direct discharge into natural water will cause pollution. However, as the rainfall progresses, the rainwater will become cleaner and cleaner. and production water, but the existing rainwater treatment is to discharge the initial rainwater and the later rainwater mixedly, which has not been rationally utilized. Contents of the invention [0003] The object of the present invention is to provide a rainwater quality control regulation and storage system and a control method aiming at the defects of the prior art. [0004] The technical scheme adopted in the present invention is: a rainwater quali...
