Embodiment Construction

[0032] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0033] Such as figure 1 As shown, the embodiment of the sewage treatment structure of the low water head ecological hydropower station disclosed by the present invention includes,

[0034] A river barrage 1 that crosses both sides of the river and divides the river into an upstream section 31 and a downstream section 32. The bottom of the barrage 1 has a drainage channel 11 connecting the upstream section 31 and the downstream section 32. The drainage channel 11 is provided with a water turbine power generation assembly 12, and the output end of the drainage channel 11 is a tail water outlet 13;

[0035] The oil retaining dam 2 arranged in the downstream section 32, the oil retaining dam 2 crosses both banks of the river, and the two sides of the oil retaining da...

Abstract

The invention discloses a low-water-head ecological hydropower station waste water treatment structure. A river intercepting dam for dividing a riverway into an upstream reach and a downstream reach,an oil intercepting dam, an impeller assembly and an oil scraping assembly are included. The bottom of the river intercepting dam is provided with a drainage channel communicating with the upstream reach and the downstream reach. The drainage channel is internally provided with a water wheel power generation assembly, and a tail water port is formed in the output end of the drainage channel. The oil intercepting dam is arranged on the downstream reach, the area between the oil intercepting dam and the river intercepting dam is an oil removal channel, the tail water port communicates with the oil removal channel, the lower edge of the oil intercepting dam is located below the liquid surface of the downstream reach, and a water passing channel is reserved. The impeller assembly is arranged in the oil removal channel and in front of the tail water port, and tail water from the tail water port impacts on the impeller assembly for rotation. The oil scraping assembly is arranged in the oil removal channel and is in transmission connection with the impeller assembly. The provided low-water-head ecological hydropower station waste water treatment structure can treat oil dirt generated by ahydropower station, and ecological protection of hydropower station downstream riverways is facilitated.

Description

technical field [0001] The invention relates to the technical field of hydropower stations, in particular to a sewage treatment structure for low-head ecological hydropower stations. Background technique [0002] A hydropower station is a comprehensive engineering facility that can convert water energy into electrical energy. Low-head hydropower stations are mostly set up in the middle and lower reaches of rivers. The water flow in the middle and lower reaches of the river is gentle, which is suitable for the growth of fish and shrimp. The river water is mostly diverted for irrigation, etc., and it is close to the mouth of the sea. The ecological protection of the middle and lower reaches of the river is very important. [0003] Although hydroelectric power generation is a clean and renewable energy source without pollution, at present, hydropower stations need to use various electromechanical equipment for power generation. After long-term use of the equipment, there is a ...
