Embodiment Construction

[0014] Such as figure 1 As shown, the present invention mainly consists of water inlet pipe 1, filter material 2, overflow port A 3, pressure valve 4, overflow port B 5, membrane 6, sump 7, concentrated sewage drain pipe 8, clear water drain pipe 9, sunny day Sewage drainage pipe 10, emptying pipe A 11, inner wall 12, partition wall 13, membrane installation wall 14, outer wall 15, and emptying pipe B 16.

[0015] The sewage first enters the device through the water inlet pipe 1 on the outer wall 15, and the sewage is pretreated through the annular filter material layer 2 to remove larger pollutants such as branches and leaves. The pretreated sewage passes through the overflow on the inner wall 12. Port A3 enters the collection chamber. When the amount of sewage is small, the pressure valve 4 is opened, and the sewage is discharged into the pipe network from the drain pipe 10 and enters the sewage plant for treatment. The pressure valve 4 is controlled by the water pressure; w...

Abstract

The invention discloses a sewage concentration device, which comprises a sewage pretreatment device, a sewage drainage device and a sewage concentration drainage device. The sewage pretreatment device comprises a special filter material layer; the sewage drainage device comprises a pressure valve, when water flow is low, the pressure valve is automatically opened so that sewage is drained, and when the water flow is high, the pressure valve is closed automatically; and the sewage concentration drainage device comprises a membrane, a water gathering tank, a clear water drainage tube and a concentrated sewage drainage tube. When sewage flow is high, the sewage can be concentrated, so that the flow of the sewage entering a sewage plant is low, treated sewage load is reduced, and simultaneously, pressure of a pipe network is reduced. The sewage is concentrated and filtered to form clear water, and the clear water is drained to a downstream river way.

Description

technical field [0001] The invention relates to a device for concentrating and discharging sewage, in particular to a device for concentrating, collecting, discharging and reusing the sewage in rainy days. Background technique [0002] Most of the existing systems in small and medium-sized cities and towns adopt the direct discharge combined system, and most of the sewage is directly discharged into the water body without treatment, causing the pollution of the natural water body and deteriorating the urban environment. Selecting the intercepting combined drainage system and the existing pipes and channels in cities and towns can effectively treat the sewage. It is economical and reasonable for small and medium-sized towns. The intercepting combined drainage system is to lay intercepting main pipes in parallel along the water body to collect sewage from various branch pipes and main pipes, and set several intercepting wells at appropriate positions of the intercepting main ...
