Problems solved by technology
[0003] However, the above-mentioned facilities are generally composed of multiple structural parts, which increases the occupied area. Due to the limited space around the rivers in many cities, it is not conducive to the intensive treatment of overflow rainwater and sewage.
At the same time, the coagulation process requires coagulant and other agents, and the system relies on electric energy to operate, which increases the purification cost, and the structure is more complicated and the cost is higher. Since this type of device is a purely engineering measure, it has not been effectively integrated with the surrounding environment, and the landscape coordination is relatively poor. Difference

Embodiment Construction
[0018] The present invention will be further described below in conjunction with accompanying drawing.
[0019] figure 1 The cascade ecological pollution control shore-type structure is used to absorb the overflow rainwater on the spot, including the homogeneous well (2) and the main structure part of the brick-concrete cascade structure (5), and the overflow rainwater is passed through the overflow pipe (1) After flowing into the homogeneous well (2), it enters the uniform water distribution support layer (3) of the first-level structure from the bottom of the homogeneous well (2), and the overflow rainwater is distributed to the steel bars through the water distribution corridor. For each part of the concrete slit slab, the overflow rainwater that is uniformly arranged through the reinforced concrete slit slab is absorbed by the biological interception adsorption filler, and the upper plant matrix layer (7) is comprehensively purified and then dropped by the triangular weir...

Abstract
The invention discloses an overflowing rain sewage on-site elimination stepped ecological sewage control structure, which is a shore type structure and is provided with a cascade ecological treatment and purification system. In the overflowing rain sewage on-site elimination stepped ecological sewage control structure, connecting structures are built by using water permeable bricks in a certain proportion; and a water uniform distribution supporting layer, biological interception and absorption packing, biological filtering packing, a vegetable substrate layer and a triangular-notch weir are arranged between an overflowing rain sewage incoming place and an outgoing place. The structure of the invention overcome the drawbacks of large floor area, high medicament consumption and high energycost and the like of the conventional overflowing rain sewage on-site treatment facilities. The structure of the invention is simple, low in construction cost, free from operating power and convenient to operate and maintain, can be used all the year round, offers desirable sewage control effect and can be used in water environmental pollution control ecological projects.
Description
technical field [0001] The invention relates to a cascaded ecological pollution control structure for on-site sewage consumption for the control of water environment pollution, in particular to an ecological pollution control structure for on-site consumption of overflow rainwater. Background technique [0002] Before the invention of the present invention, there were many existing technologies and devices or facilities for purifying overflow rainwater and sewage on the spot. Especially for overflow rainwater with obvious initial effect, storage tanks were used to store initial overflow rainwater and added The coagulant is discharged after precipitation or sent to the sewage treatment plant for treatment in the dry season to achieve the purpose of controlling the pollution of overflow rainwater and sewage. [0003] However, the above-mentioned facilities are generally composed of multiple structural parts to increase the occupied area. Due to the limited space around the riv...
