Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.The present embodiment is implemented premised on technical solutions of the utility model, give detailed embodiment and concrete operating process, but protection domain of the present utility model is not limited to following embodiment.
A kind of circular storm detention tank being equipped with automatic cleaning equipment, this storm detention tank is connected with municipal drainage pipe network by rainwater collection collector 14, as depicted in figs. 1 and 2, circular storm detention tank comprises vacuum pump 2, vacuum diaphragm valve 3, developing room 5, siphon unit 6, sludge-tank 7, pond body 9 and atmospheric valve 13, be connected with sludge-tank 7 bottom pond body 9, sludge-tank 7 is positioned at pond body 9 bottom outside, developing room 5 is located at pond body 9 central authorities, bottom is connected with pond body 9 by siphon unit 6, developing room 5 top is connected with vacuum pump 2 by vacuum diaphragm valve 3, sludge-tank 7 is connected with blow-off line 15 by atmospheric valve 13, blow-off line 15 is located at around circular storm detention tank.
Wherein the scale of pond body 9 is determined according to the parametric synthesis such as amount of precipitation, rainfall intensity, service area, the runoff coefficient of service range, the pollution reduction target of storage pond of locality, and the parameter model of its intermediate pump 2 and vacuum diaphragm valve 3 is determined according to actual conditions.
Wherein the installing space size of vacuum diaphragm valve 3 is not less than 700mm × 900mm, and the spacing of distance periphery structure is not less than 250mm.
Wherein the peak level of developing room 5 reaches as high as 7m, and general control is at 4 ~ 5m.
Wherein the diameter of developing room 5 is not less than 100cm, is convenient to maintenance personal if desired and enters.
Wherein the washing water quantity of developing room 5 is determined according to the diameter of pond body 9, bottom gradient and the first-class parametric synthesis of flushing water.
According to the diameter of pond body 9, consult Fig. 3 and can obtain washing water quantity.When bottom pond body 9, gradient is less than 0.5%, washing water quantity will suitably increase.
Circular storm detention tank also comprises alternate source 8, and alternate source 8 is connected with sludge-tank 7.
