Embodiment 1

[0045] Such as figure 1 and figure 2 As shown, a low-control source sewage interception system includes interception and purification functional area 1 set at the outlet on both sides of the river 11, interception and purification functional area 1 includes ecological retention and purification ditch 4 and rainwater pretreatment facility 5, ecological retention and purification ditch 4 It is installed at the place where the sewage enters the river, and the rainwater pretreatment facilities 5 are installed at the rainwater outlets on both sides of the river bank. The sewage from the outlets on both sides of the river channel 11 enters the river. It is difficult to intercept sewage or there is still a problem of pollution entering the river after intercepting sewage. Ecological interception is applied. The purification ditch 4 and the rainwater pretreatment facility 5 intercept a small amount of sewage and intercept the initial rainwater and discharge it directly into the river...

Embodiment 2

[0052] Basically the same as embodiment 1, preferably, described ecological interception purification ditch 4 comprises aerobic section B, anoxic section A and adsorption section C according to the function division of water body, described anoxic section A length, aerobic section B length The ratio to the length of the adsorption section C is 1:1.5:1. This ratio is calculated based on the water quality and quantity of the intercepted sewage and according to the normal discharge standard. Under this ratio, it can meet the purification requirements of the water body and meet the Reach different purification requirements in the water quality of different characteristics, improve the water quality in the ecological interception purification ditch 4; as Figure 4 As shown, the aerobic section B is provided with aquatic plants 7, and a biological filler 16 is arranged below the aquatic plants 7. Preferably, the biological filler 16 is an active biological filler, which adopts a scie...

Embodiment 3

[0055] Basically the same as embodiment 2, preferably, described ecological interception purification ditch 4 comprises aerobic section B, anoxic section A and adsorption section C according to the function division of water body, described anoxic section A length, aerobic section B length The ratio to the length of the adsorption section C is 1:3:5. This ratio is calculated based on the water quality and quantity of the intercepted sewage and according to the normal discharge standard. Under this ratio, the sewage in the three sections can be discharged Obtain different purification under different environments, improve the water quality in this ecological interception purification ditch 4; Figure 4 As shown, the aerobic section B is provided with aquatic plants 7, and a biological filler 16 is arranged below the aquatic plants 7. Preferably, the biological filler 16 is an active biological filler, which adopts a scientific formula, and the properties of sewage are different ...

Abstract

The invention discloses a low source-controlling sewage-intercepting system and a construction method, belongs to the technical field of riverway regulation, and aims at solving the problem that source-controlling sewage-intercepting in the prior art for sewage has incompletion in sewage interception, poorer water body quality and a complex decontamination system. The low source-controlling sewage-intercepting system disclosed by the invention comprises interception purification function areas, wherein the interception purification function areas are arranged on drainage openings on the two sides of a riverway; each interception purification function area comprises an ecological interception purification ditch and rainwater pretreatment facilities, the ecological interception purificationditch is arranged at the position where sewage is drained into river, and the rainwater pretreatment facilities are arranged at the rainwater discharge openings on the two shores of a river bank; theriverway is provided with econological function areas, and the downstream riverway is provided with strengthened purification function areas. As the function areas are scientifically divided, a complete, function-complementing low source-controlling sewage-intercepting system is formed, ecological self-cleaning capacity of the riverway can be restored and enhanced, suspended solid, dissolved organic matters and nitrogen and phosphate nutritive salt in water can be effectively reduced, and water quality is stably controlled. The construction method for the low source-controlling sewage-intercepting system disclosed by the invention has the advantages of simple construction and low cost.

Description

technical field [0001] The invention belongs to the technical field of river course management, and more specifically relates to a low-control source sewage interception system and a construction method. Background technique [0002] With the rapid development of economy and society and the continuous expansion of cities, in the process of urban construction, the pollution of my country's urban water environment is becoming more and more serious. The water bodies in urban rivers are mostly polluted by organic pollutants, nitrogen, phosphorus and other pollutants. It is a common phenomenon in the rivers of cities in our country, and the governance of urban black and smelly rivers will be an environmental problem to be solved in the future. In terms of urban drainage and treatment of black and odorous water bodies, China has always focused on the research of sewage treatment technology, and paid little attention to the urban drainage system. When dealing with the urban drainag...
