The floating plate 32 is supported by foam and fixed at one end of the telescopic tube 31 far away from the filter cartridge 21, and a plurality of air inlets are arranged on the floating plate 32. When the rainfall increase in the cartridge filter 21, the water level in the cartridge filter 21 rises to produce thrust to the kickboard 32, make the kickboard 32 drive flexible pipe 31 extension, with the water storage capacity that enlarges the cartridge filter 21, make things convenient for the rainwater to carry out short persistence in the cartridge filter 21, provide buffer space to the subsequent processing of rainwater. Meanwhile, the air inlet hole can compensate air in the extension tube 31, so that the air pressure in the extension tube 31 is kept consistent with the external air pressure, and the extension of the extension tube 31 is facilitated.
Referring to fig. 6 and 7, the waste-water settling device 4 includes a settling cylinder 41, and the settling cylinder 41 is a circular cylinder with an open end and an upward opening. The open end of the settling cylinder 41 is also connected with a buffer member 3 in a sealing way for expanding the water storage capacity of the settling cylinder 41. The sedimentation cylinder 41 is communicated with a water inlet 411 and a water outlet 412 along the circumferential direction, the water inlet 411 is communicated with the water outlet pipe 212 through a water conveying pipe, and the water outlet 412 is communicated with the water reservoir 61 through another water conveying pipe. The side wall of the settling barrel 41 is also communicated with a sewage outlet 413 for discharging sediments, and the sewage outlet 413 is connected to a rainwater and sewage well.
The settling cylinder 41 is provided with a blocking plate 42 between the sewage outlet 413 and the water inlet 411 and the water outlet 412, and the blocking plate 42 is fixed on the inner wall of the settling cylinder 41. The blocking plate 42 is used for separating the sewage outlet 413 from the water inlet 411 and the water outlet 412, and a through hole 421 is formed in the center of the blocking plate 42. One side that shutoff board 42 deviates from a sediment section of thick bamboo 41 diapire has been seted up if each hole 422 that permeates water, and the hole 422 that permeates water evenly distributed on shutoff board 42, and shutoff board 42 radially offers the water conservancy diversion hole 423 that is used for communicateing hole 422 that permeates water and through-hole 421. One side of the plugging plate 42, which is far away from the bottom wall of the sedimentation cylinder 41, is in an arc groove shape, and the thickness of the plugging plate 42 is gradually increased from the through hole 421 to one side of the sedimentation cylinder 41, so that rainwater or sediment can be collected to the through hole 421.
Meanwhile, a sealing member 5 for sealing the through hole 421 is arranged in the sedimentation cylinder 41, the sealing member 5 comprises a support rod 51 fixed on the sedimentation cylinder 41, and the support rod 51 is arranged on one side of the sealing plate 42 departing from the bottom wall of the sedimentation cylinder 41. A sliding rod 52 is inserted through the through hole 421 in the support rod 51, and the sliding rod 52 is slidably disposed on the support rod 51. The sliding rod 52 is provided with a floating ball 54 between the supporting rod 51 and the blocking plate 42, and the floating ball 54 is made of plastic foam. The slide rod 52 is connected with a limit nut 55 at one side of the support rod 51 departing from the floating ball 54 through a thread, and an operator can adjust the height of the floating ball 54 by rotating the limit nut 55, so that the operator can adjust the distance between the floating ball 54 and the through hole 421. One end of the sliding rod 52 far away from the floating ball 54 passes through the through hole 421 and is fixedly connected with a blocking ball 53, and the diameter size of the blocking ball 53 is larger than that of the through hole 421.
After rainwater enters the precipitation cylinder 41, the precipitation cylinder 41 is filled with rainwater instantly, the floating ball 54 is floated by the rainwater, and the buoyancy is larger than the gravity of the blocking ball 53, so that the floating ball 54 drives the blocking ball 53 to ascend. At this time, the blocking ball 53 abuts against the lower edge of the through hole 421, so as to achieve the effect of blocking the through hole 421. Meanwhile, rainwater is precipitated in the precipitation cylinder 41, when rainfall stops, the rainwater level in the precipitation cylinder 41 gradually drops, and the buoyancy of the rainwater on the floating ball 54 is reduced. So that the blocking ball 53 is separated from the through hole 421 by the self gravity of the blocking ball 53, thereby allowing the sediment on the blocking plate 42 to be rapidly discharged through the through hole 421.
The embodiment of the application also discloses a sewage treatment method.
