A kind of water conservancy project environment-friendly purification and filtering equipment

Abstract

The invention discloses a water conservancy project environment-friendly purification and filtering equipment, which comprises a manhole cover, the front and rear ends and both sides of the manhole cover are fixedly installed with sliders, and a ring groove is arranged on the upper end of the manhole cover close to the outer ring, And the inside of the ring groove is provided with a first filter screen, the outside of the manhole cover is provided with a protection mechanism, and the outer surface of the upper end of the manhole cover is provided with a stopper at the position close to the middle, and the lower end of the manhole cover is provided with a water collecting cylinder, and the water collecting cylinder The lower end of the water collecting cylinder is provided with an anti-blocking mechanism at the position close to the left side, and the lower end of the water collecting cylinder is provided with a scraping mechanism at the position close to the right side; wherein, the protection mechanism includes a chassis and a semicircular blade, and the number of the semicircular blades is four indivual. The invention can facilitate the infiltration and purification of the sewage in the market street, reduce the waste gas entering the sewer pipe, reduce the introduction and accumulation of sediment into the sewer pipe, and speed up the discharge speed of the sewage in the sewer pipe.

Description

technical field [0001] The invention relates to the technical field of purification and filtration equipment, in particular to an environment-friendly purification and filtration equipment for water conservancy projects. Background technique [0002] A water conservancy project is a project built for the purpose of controlling and allocating surface water and groundwater in nature to achieve the purpose of eliminating harm and benefiting, also known as water engineering; water is an indispensable and valuable resource for human production and life, but its natural existence. The state does not fully meet the needs of human beings. Only by building water conservancy projects can we control water flow, prevent flood disasters, and adjust and distribute water to meet people's needs for water resources in life and production. [0003] In daily water conservancy projects, water resources will contain sediment, which is usually discharged directly after sewage treatment, which wil...

AI Technical Summary

Problems solved by technology

[0005] 1. Although the above-mentioned device can effectively collect the sediment in the sewage and avoid direct discharge to pollute the environment, when facing the discharge of sewage in the market, especially for the seafood market, due to the inclusion of There are a lot of pollutants and wastes, if the sewage is discharged directly, it may cause the grid of the manhole cover and the sewer to be blocked at the same time; when the drainage is large, if the manhole cover is raised to drain, part of it will rise or even overflow when the drainage is urgent , the position where the sewage covers the sewer hole may cause pedestrians to accidentally fall into the sewer, causing danger;

[0006] 2. In the process of selling seafood in the seafood market, there are often discarded fish and seafood viscera after disposal. After discarding, a small part of them mixed with blood, water, cleaning water, etc. flow into the sewer, especially for hot weather, after soaking in high-temperature water for a period of time Rotting will produce pungent air temperature, and the gas will be discharged into the sewer together with the sewage, causing the smell in the well to be unable to dissipate, and indirectly forming gas pollution;

[0007] 3. A large amount of silt and silt deposits will inevitably appear in the shaft of the traditional sewer pipe. If the silt accumulates at the water inlet, it will affect the flow and discharge of sewage, and will lead to the content of sediment pollutants in the discharged sewage. Higher, inconvenient for sewage purification
