Description

Suitable for urban river water storage and sludge removal circulation system

Technical Field

The invention relates to the technical field of urban river sewage purification, and in particular to a circulation system suitable for urban river water storage and sludge removal.

Background technique

In the traditional construction of urban river embankments, people focus on the various economic requirements of water supply, flood control, and navigation, and basically pursue economic and social benefits. They rarely consider the ecological functions of rivers such as natural ecology, rest and entertainment, and landscape. Embankment construction is only non-ecological engineering such as reinforcing embankments, cutting bends, and building spur dikes. However, human regulation of urban river flow and traditional river bank protection have formed discontinuities and barriers in the river structure, changing the water and material exchange between the river channel and the riverbank. After the riverbank is hardened, the original riverbank surface is closed, isolating the river channel from the riverbank, separating the relationship between soil and water, and isolating the contact between organisms and microorganisms in the river channel and the earth. The filtering and purification function of the river ecological corridor will be lost, the water quality will decline, and the overall balance of the river ecosystem will be destroyed. Therefore, flood storage ecological embankment technology came into being. Flood storage ecological embankments not only have flood control functions, but also can store water, retain floodwaters and replenish droughts, and realize flood resource utilization.

Beneficial effects of the present invention: The present invention can realize the function of continuous pollution removal along the longitudinal direction of the river channel with the help of the internal space of the river bank. The silt sediment at the bottom of the river channel is extracted by a water pump, and converted into the silt channel in a circulating manner, and then a silt cart is used to discharge the silt outward. Thus, the purpose of cleaning the river channel without draining all the river water is achieved. And it can achieve a continuous and uninterrupted purification effect. The pollution removal process occurs in the silt dark channel and does not affect the environment. The silt open channel is the silt output end and can be set in a sewage sludge treatment plant, thereby achieving the effect of silt not being exposed. The present invention first discharges the main silt through the vertical channel through the bottom inclined drainage channel to achieve preliminary filtration. In order to concentrate the silt in the silt channel, the second water pump is used for circulating extraction, so as to keep a large amount of silt continuously entering the silt channel through the vertical channel. The amount of silt and water entering the vertical channel can be controlled by adjusting the slide plate, so that the purpose of circulation can be achieved to different degrees according to the water quality of the river channel.
