Embodiment Construction
[0022] The present invention provides a process and system for collecting and purifying rainfall runoff by quality. The present invention will be further described below in conjunction with the accompanying drawings and specific implementation methods.
[0023] Such as figure 1 As shown, an interception pool 3 with a section similar to a right-angled trapezoid is set on the rainwater pipe 2, and the interception pool 3 is welded by seamless steel plates with a length of 3 m and a width of 1.5 m. A cleaning tipping bucket 4 is arranged on the upper part of the front side wall of the intercepting pool 3 below the rainwater pipe 2, and its lower left side is welded together with the bearing and the intercepting pool body, and there is a bolt on the upper right for fixing; The width is the same, and its side section is a square of 0.3×0.3m, which can store 135L runoff in total. The bottom of the interception pool 3 is a slope, which is inclined downward from the position below th...
