Embodiment Construction

[0023] This example is carried out in a simulation device. Ditch water samples were taken for the sewage used in the experiment.

[0024] Experimental process and conditions: the position of the experimental tank is high or low to simulate the drop of the river slope, and it flows into the lower experimental tank by itself. After entering the sediment tank with agitator and overflowing through the absorption and percolation of aquatic plants, it is sealed and pumped into the storage tank under negative pressure. The water bottle then naturally drops into the experimental cylinder at the same speed; during the experiment, the fluorescent lamp is used to irradiate light according to the natural light-dark ratio; there is a two-stage percolation of PFU (polyurethane foam block) A inside, and its function is to make the micro organisms therein active. A living space for decomposing pollutants; the same kind of aquatic plants are planted in the sedimentation tank, and the same numb...

Abstract

A river ditch sewage ecological strengthening self cleaning method is as follows: river ditch sewage passes through bio-based weir wetland oxidation pond comprising multi stage base weirs, each stage base weir comprises a levee slope biological vegetation or a percolationmaterial, landscape aeration, sprinkler irrigation aeration, a wetland, a base weir and a base weir front sedimentation ditch and a base weir rear sedimentation ditch, and a horizontal plane between the two stage base weirs is located at the position of 1 / 2-2 / 3 of the height of an upper-stage base weir and the top of a lower-stage base weir, and the sedimentation ditches have the depth of 0.5 m and width of 1 m.

Description

technical field [0001] The invention belongs to sewage treatment technology, and more precisely relates to an ecological treatment method for water quality pollution of rivers and ditches. Background technique [0002] With the development of industry and agriculture and the continuous improvement of people's living standards, the contradiction between environmental pollution and economic development has become increasingly prominent. Among them, the public nuisance caused by water pollution has been attached great importance to by countries all over the world, and many prevention and treatment countermeasures and treatment technologies have been proposed. [0003] At present, large-scale sewage treatment plants are established, and centralized biochemical treatment of sewage is a method commonly used in the world. However, this type of method has problems such as high investment, high cost, large area, many restrictive factors for treatment effect, unstable water quality at...
