Abstract

The invention belongs to the technical field of environmental protection and in particular relates to an automatic switching system for initial rainwater collection. The automatic switching system for initial rainwater collection comprises an initial rainwater collecting pool, a ground surface runoff water collecting pipeline, an initial rainwater pipeline and a later rainwater discharge pipeline, and is characterized by further comprising an initial rainwater collection measuring system, an initial rainwater collecting system and an information collection processing control system, wherein the initial rainwater collection measuring system and the initial rainwater collecting system are connected with the information collection processing control system. The automatic switching system for initial rainwater collection can automatically switch and automatically collect initial rainwater according to an output signal from a microprocessor, and is simple in structure, low in manufacturing cost and easy to popularize.

Description

technical field [0001] The invention belongs to the technical field of environmental protection, and in particular relates to an automatic switching system for initial rainwater collection. Background technique [0002] The initial rainwater is the surface runoff water produced by continuous and discontinuous rainfall of 15-30mm from the beginning of rainfall to the set rainfall after a long period of no rainfall. The ground runoff water generated by the initial rainfall will wash away the pollutants scattered on the ground during sunny days and dissolve them in the water. Therefore, the composition of the initial rainwater is complex and various, especially the initial rainwater near industrial enterprises. The initial rainwater will be directly discharged into the river through the rainwater pipe without any treatment, which will cause environmental pollution. Therefore, the initial rainwater must be collected and treated with preliminary treatment facilities such as oil s...
