Description

Purify ecological dam device in black and odorous river course

The technical field is as follows:

the utility model relates to a black and odorous water body treatment field, concretely relates to ecological dam through biological purification-sediment-filtration technology purification quality of water.

Background art:

water is an important natural resource on which human beings rely to live, and rivers flow back and forth in cities, so that the water plays an important role in maintaining urban ecological functions. However, in the process of industrialization, due to the weak environmental protection consciousness of human beings caused by the lagged urban infrastructure, many river channels fall into the discharge areas of industrial wastewater and domestic sewage. The sewage discharge amount is large and exceeds the self-purification capacity of the river, so that the water body is lack of oxygen and eutrophicated, and the water body is blackened and smelly. Black and odorous water has become an urban disease, and almost none of all cities is fortunate.

At present, in the treatment method of the black and odorous water body, the biological method is widely applied due to the advantages of small investment, no secondary pollution and the like. The method firstly needs to control the source and cut off the pollution source from the source.

(2) The ecological dam device can realize automatic backwashing without personnel operation.

(3) The ecological dam is a dam, and only needs to be hoisted into a river channel when the source control and sewage interception are carried out, and building materials are saved when corners are plugged.

Description of the drawings:

FIG. 1: internal structure diagram

The specific implementation mode is as follows:

the present invention will be described in further detail with reference to the accompanying drawings

As shown in the figure, the ecological dam is mainly divided into four parts, namely a biological purification tank, a sedimentation tank, a filtering device and an automatic backwashing device. The biological purification tank consists of an inlet water distribution clapboard 1, an outlet water distribution clapboard 6, a quick separation ball filler 3, a filler clapboard 5, an aeration pipeline 4 and an aerator 2. The sedimentation tank consists of a sludge storage tank 9, an inclined plate filler 8, a sludge discharge port 10 and an overflow weir 7. The filtering device is composed of a head tank 11, a head tank-filtering bin communicating pipe 15, and a filtering bin 16 (a quartz sand partition plate 21, quartz sand 17, a bottom clear water zone 19, a bottom clear water zone-clear water tank communicating pipe 18, a clear water tank 20 and a water outlet 14). The automatic backwash device consists of a siphon 13, a siphon break pipe 12 and a backwash liquid collection tank 22.

Black and odorous water enters the device from the water inlet pipe, is uniformly distributed by the water inlet and distribution partition plate 1 and enters the biochemical treatment unit, the biochemical treatment unit is composed of a quick-separating ball filler 3, a large number of microorganisms can be fixed by the filler, and the filler is aerated by the aerator 2 and the aeration pipeline 4 to provide oxygen necessary for the growth of the microorganisms. The water uniformly flows out through the water outlet distribution partition plate 6 and then enters the precipitation treatment unit, the water flows from bottom to top through the inclined plate filler 8, the sludge sinks to the sludge storage tank 9 when meeting the inclined plate, the sludge is periodically discharged from the sludge discharge port 10, the water flows to the overflow weir 7 and then enters the high-level water tank 11, then reaches the filter bin 16 through the high-level water tank-filter bin communicating pipe 15, is filtered by the quartz sand 17 and then reaches the bottom clear water area 19 and then enters the clear water tank 20 through the bottom clear water area-clear water tank communicating pipe 18, and then is discharged from the water outlet 14.

The black and odorous water adopts an ecological dam purification route as follows: water inlet → water inlet distribution partition plate 1 → speed dividing ball filler 3 → water outlet distribution partition plate 6 → inclined plate filler 8 → overflow weir 7 → head tank 11 → head tank-filter house communicating tube 15 → quartz sand 17 → bottom clear water zone 19 → bottom clear water zone-clear water tank communicating tube 18 → clear water tank 20 → water outlet 14.

As the filtering action in the filtering chamber continues to run, a filter residue begins to slowly form inside and on the surface of the quartz sand 14. Since the water on the upper part of the quartz sand 14 cannot penetrate through the quartz sand layer, the water level of the high-level water tank 11 and the siphon 13 is continuously raised, and when the water level of the high-level water tank 11 exceeds the highest point of the siphon 13, the water flows out from the siphon 13 to form siphon. The clean water in the clean water tank 20 backflushes the quartz sand 17 through the bottom clean water area-clean water tank communicating pipe 18, flows from the siphon 13 to the backflushing liquid collecting tank 22 together with the water in the head tank 11, and is periodically cleaned. As the backwash progresses, the water level in the clean water tank 20 drops and when the water level drops to the mouth of the siphon break pipe 12, air enters the siphon break pipe 12, causing air to enter the siphon 13, the backwash ends and filtration resumes.
