A purification and reuse system for rainwater collection

Abstract

The invention discloses a rainwater collection purification and reuse system, comprising a rainwater collection unit, the lower end of the rainwater collection unit communicates with a pH adjustment unit through a connecting pipe, and the pH adjustment unit communicates with an ultraviolet disinfection unit through a second electromagnetic valve and a connecting pipe Connected; a motor is fixedly installed on the shell of the PH adjustment unit, and the motor is rotatably connected with the hollow disk, and a circular baffle is installed on the inner side of the hollow disk, and the left side wall of the circular baffle and the hollow The inner side of the disc is staggered with arc-shaped grooves, and the side wall of the circular baffle is fixed with stirring fan blades, and the stirring fan blades pass through the arc-shaped grooves on the side wall of the hollow disc and extend into the inner cavity of the pH adjustment unit , the interior of the hollow disc is provided with an alkali block. This device not only speeds up the PH neutralization efficiency, but also avoids the situation where excessive alkali dosage requires static filtration again, and even causes severe alkalization of rainwater, which is more practical.

Description

technical field [0001] The invention belongs to the technical field of rainwater purification, and in particular relates to a purification and reuse system for rainwater collection. Background technique [0002] There is a shortage of water resources in my country, especially in most urban-centered areas. Rainwater is a high-quality freshwater resource in nature. After treatment, it can realize the functions of flushing toilets, road spraying, and greening watering. Reusing rainwater can save water significantly. efficacy. [0003] PH neutralization treatment is required in rainwater recovery, and a certain amount of alkali needs to be put in during treatment. However, during the process of adding alkali, there is an excessive amount of input. It is necessary to increase the step of standing for secondary filtration, which is time-consuming and labor-intensive, and even causes rainwater. In the case of severe alkalization, it is necessary to solve the above problems. SUMMA...
