Unpowered riverside water ecology conservation and purifying system

Abstract

An unpowered riverside water ecology conservation and purifying system comprises a transverse gutter arranged on the upstream riverside of a landscape riverway rubber dam or hydraulic dam. A grating and a sluice valve are sequentially arranged at an entrance of the transverse gutter from left to right, a vertical gutter is vertically arranged at the tail end of the transverse gutter, the left sidewall of the vertical gutter is a first water distribution lattice wall while the right side wall of the same is a second water distribution lattice wall, and a plurality of landscape units are arranged between the first water distribution lattice wall and a riverway; a plurality of overflow holes are formed in the top of the first water distribution lattice wall and the left side wall of each landscape unit, a third water distribution lattice wall is parallelly arranged on the right side of the second water distribution lattice wall, a gravel filtering strip is formed between the second waterdistribution lattice wall and the third water distribution lattice wall and divided into gravel filtering units corresponding to the landscape units, a plurality of precipitation troughs corresponding to the gravel filtering units are arranged on the right side of the third water distribution lattice wall, and anticorrosion wooden trestles are paved to the tops of the gutters, the gravel filtering units and the precipitation troughs.

Description

technical field [0001] The invention belongs to the technical field of water treatment, in particular to a non-powered riverside water ecological maintenance and purification treatment system. Background technique [0002] With the rapid development of my country's economy, the speed of urbanization and industrialization is getting faster and faster, people's quality of life and standard are improving, and residents' requirements for living environment are getting higher and higher. Therefore, various rivers have been transformed one after another. Large-scale hardening and semi-hardening revetment construction at the bottom and river banks, landscaping on both sides of the river, hardening of roads and squares, making the entire river into beautiful landscape green corridors, greatly improving the landscape of the urban living environment However, at the same time, the wetlands, tidal flats, aquatic animals and plants in the original river channel have completely disappeared,...

AI Technical Summary

Problems solved by technology

If water pumps are used to lift the river water into a relatively high artificial wetland treatment system, and then flow back to the river after treatment, due to the huge amount of water in the river, the lifting of the water pump consumes a lot of energy and high operating costs. It is difficult to acquire land for cultivated land and residential land, and the cost of land acquisition is high, which increases the construction cost in disguise

There are also some in-situ ecological restoration of river channels, such as ecological floating beds, bioaugmentation, etc., but considering factors such as the hydraulic load and hydraulic retention time of the river water, the growth and purification effects of plants and bacteria will be limited, and the river flow rate will increase slightly. Systematic biological culture needs to be restarted

Another method is to build a landscape-type multi-step artificial wetland slope protection on the river bank. This method can play a good role in intercepting non-point source pollution entering the river in rainy days, but when there is no rain, it cannot achieve purification and cannot Purify the water in the river
