Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be further described in detail with reference to the accompanying drawings and embodiments, it should be understood that the embodiments described herein are only for explaining the present invention, and are not intended to limit the present invention, the distribution pump station of rain and sewage of the present invention comprises a cylinder 5, a water inlet pipe 1 and a water outlet pipe 4, the water inlet pipe 1 and the water outlet pipe 4 are respectively disposed on the side wall of the cylinder 5, a sewage pump 7 is disposed inside the cylinder 5, sewage is discharged through the sewage pump 7 via a sewage pipe 6, a compartment 8 is further disposed inside the cylinder 5, a grid 2 is disposed inside the compartment 8, the grid 2 is connected with the end of the water inlet pipe 1, a sewage valve 3 is further disposed on the compartment 8, a liquid level meter 9 and a ladder stand 12 are mounted inside the cylinder 5, the liquid level meter 9 and the sewage pump 7 are connected with a control cabinet 10 via a cable, a rain gauge 11 is disposed outside the pump station, the sewage treatment device is connected with a control cabinet through a cable, only sewage enters into a separation cavity 8 from a water inlet pipe 1 in sunny days, impurities are blocked by the grating 2 when the sewage passes through the grating 2, then a blow-down valve 3 is in an open state, the sewage enters into a barrel 5 through a blow-down hole 83, when a liquid level meter 9 detects that the liquid level in the barrel 5 reaches a set pump starting liquid level, a blow-down pump 7 is started, the sewage is discharged into a sewage pipe network through a blow-down pipe 6, when the liquid level in the barrel 5 drops to a pump stopping liquid level, the blow-down pump 7 stops pumping, when the liquid level is lower than the weather, a rain gauge 11 arranged outside a pump station detects real-time rain data and transmits the real-time rain data into the control cabinet, the rain data does not reach the condition of discharging rainwater, the rainwater and the sewage enter into the separation cavity 8 from the water inlet pipe 1, the sewage passes through the grating 2, the impurities are blocked by the grating 2, and then the blow-down valve 3 is in an open state, sewage enters the barrel body 5 through the sewage discharge hole 83, and when the liquid level gauge 9 detects that the liquid level in the barrel body 5 reaches the set pump starting liquid level, the sewage discharge pump 7 is started to discharge the sewage into a sewage pipe network through the sewage discharge pipe 6. When the liquid level in the barrel 5 is lowered to the liquid level of the pump stop, the sewage pump 7 stops pumping, in heavy rain, a rain gauge 11 arranged outside a pump station detects real-time rainfall data and transmits the real-time rainfall data to a control cabinet, the rainfall data already reaches the condition of draining rainwater, but in the early stage of rain, as the initial rainwater is dirty, the rainwater and the sewage enter the separation cavity 8 from the water inlet pipe 1, the sewage passes through the grating 2, sundries are blocked by the grating 2, the sewage valve 3 is in an open state at the moment, the sewage enters the barrel 5 through the sewage hole 83, when the liquid level gauge 9 detects that the liquid level in the barrel 5 reaches the set pump starting liquid level, the sewage pump 7 is started, the sewage is drained into the sewage pipe network through the sewage pipe 6, when the liquid level in the barrel 5 is lowered to the liquid level of the pump stop, the sewage pump 7 stops pumping, and after the initial rainwater is collected, the sewage valve 3 is closed, at this time, the rainwater and the sewage are discharged into the natural water body through the water outlet pipe 4 arranged at the other side of the separate cavity 8. At the end of raining, when the rain gauge 11 detects that the real-time rainfall reaches a set value, the drain valve 3 is opened, rainwater and sewage enter the barrel 5 through the drain hole 83, the opening and the stopping of the drain valve 3 and the drain pump 7 are controlled through the rain gauge 11 and the liquid level meter 9, the rainwater and the sewage during raining are separated, the initial rainwater and the sewage are effectively isolated by the partition cavity 8 and then discharged, the rainwater and the sewage are prevented from being directly discharged into a natural water body after being mixed, meanwhile, the clear water is prevented from being discharged into a sewage pipe through the drain pump, meanwhile, as the grating and the drain valve are both arranged in the partition cavity, the biogas is isolated, and therefore, the risk of poisoning of people is reduced, as shown in fig. 1 and fig. 2, the drain hole 83 is arranged on the bottom partition plate 82 of the partition cavity 8, as also can be as shown in fig. 3, the drain hole 83 is arranged on the side partition plate 81 of the partition cavity 8. The effect is the same when the bottom partition 82 and the side partition 81 are provided.
