Problems solved by technology

[0007] The above-mentioned ecological treatment technologies have their own advantages and disadvantages, but they are not very applicable in areas where tidal rivers take into account both flood control and drainage functions. Therefore, there is an urgent need for an ecological treatment process for tidal rivers that takes into account both flood control and drainage functions.

Embodiment 1

[0027] Embodiment 1: as figure 1 As shown, the present embodiment is a river ecological treatment system for eliminating the black and odorous water body of the tidal river course. The interception net 1, the water body mixing zone 2, the water body treatment section (comprising the non-biological carrier zone 11 and the Biological carrier area 6), sand settling mud collection bucket 3 and low barrage 4, the oxygenation system for the water body in the river channel is provided with oxygenation system in the river course, corresponding sand settling mud collection bucket 3 is set on the bank to draw out mud and sand pump 10, is convenient to Regularly clean up the silt in the sand collecting mud bucket 3.

[0028] In this embodiment, the intercepting net 1 adopts a plastic net, which is used for filtering and intercepting river course garbage, so as to avoid the impact of upstream river course garbage on subsequent ecological processes.

[0029] In this example, the length of...

Embodiment 2

[0042] Embodiment 2: This embodiment is basically the same as Embodiment 1, except that the length of the water body mixing zone 2 along the water flow direction in this embodiment is 3m; the arrangement interval of the aeration branch pipes 8 is 35m; A biological carrier area 6 with a length of 15m along the water flow direction is set at 420m; the low barrage 4 is 0.5m high, and the sand settling and mud collecting bucket 3 is dug 0.3m deep and 0.4m wide.

[0043] The processing technology of the present embodiment is as follows:

[0044] The incoming water quality of the rain source type tidal channel is as follows: COD cr The concentration is 110mg / L, NH 3 -N concentration is 20mg / L, TP concentration is 1.2mg / L. After the incoming water is filtered and intercepted by the intercepting net 1 to intercept river waste, it enters the water body mixing zone 2, and the water body is repeatedly mixed up and down to improve the water body mixing effect.

[0045] After aeration a...

Embodiment 3

[0052] Embodiment 3: This embodiment is basically the same as Embodiment 1, except that the length of the water body mixing zone 2 along the water flow direction in this embodiment is 2m; the arrangement interval of the aeration branch pipes 8 is 50m; A biological carrier area 6 with a length of 10m along the water flow direction is set at 600m; the low barrage 4 is 0.3m high, and the sand settling and mud collecting bucket 3 is dug 0.2m deep and 0.3m wide.

[0053] The processing technology of the present embodiment is as follows:

[0054] The incoming water quality of the rain source type tidal channel is as follows: COD cr The concentration is 80mg / L, NH 3 -N concentration is 12mg / L, TP concentration is 0.8mg / L. After the incoming water is filtered and intercepted by the intercepting net 1 to intercept river waste, it enters the water body mixing zone 2, and the water body is repeatedly mixed up and down to improve the water body mixing effect.

[0055] After aeration an...

Abstract

The invention relates to an ecological riverway treatment system for eliminating a black and odorous water body of a tidal riverway. The invention aims to provide the ecological riverway treatment system for eliminating the black and odorous water body of the tidal riverway, which is simple in structure, low in construction and operation cost, convenient in maintenance management and good in decontamination effect. Through the technical scheme, the ecological riverway treatment system for eliminating the black and odorous water body of the tidal riverway is characterized in that the riverway is internally provided with an oxygenation system for oxygenating the water body inside the riverway; the riverway is internally provided with an interception net for intercepting garbage inside the riverway, a water body mixing area for improving the mixing effect of the water body inside the riverway and a water body treatment section for treating the water body in the flowing direction of the water body in sequence; and the down stream of the water body treatment section is provided with a sand setting mud collection hopper and a low barrage in sequence. The system is applicable to the fieldof ecological riverway technology.

Description

technical field [0001] The invention relates to a river channel ecological treatment system for eliminating black and odorous water bodies in tidal channels. It is suitable for the field of river ecology technology. Background technique [0002] Tidal rivers are affected by ebb and flow and runoff. Pollutants will flow back and forth in the river, staying for a long time, pollutants cannot be diffused in time, and pollutants are easy to accumulate. This not only deteriorates the water body of the river, but also causes river sediment pollution. Therefore, in densely populated areas and developed areas with dense factories, the pollution of tidal rivers is particularly serious. The actual application effect of various ecological treatment technologies adopted in the market is not ideal, and this type of river course has become the focus and difficulty of treatment in the task of eliminating black and odor in built-up areas. [0003] At present, the direct purification or on...
