Canine tooth spliced type multi-union ecological purification pond

Abstract

The invention discloses a canine tooth spliced type multi-union ecological purification pond which comprises a purification pond, a plurality of porous purification bricks, aquatic plants and a plurality of baffle strips, wherein the water inlet of the purification pond is communicated with a canal; the plurality of the baffle strips are arranged at the bottom of the purification pond; the bottomof the purification pond is partitioned into a plurality of long-stripy zones by the plurality of the baffle strips; the aquatic plants and the porous purification bricks are fixed at intervals amongthe plurality of the baffle strips; a plurality of porous purification bricks are arranged at intervals between adjacent baffle strips; two adjacent rows of the porous purification bricks are arrangedin a staggered manner. By adopting the purification pond, three water purification means of plant absorption, microorganism degradation and photocatalysis removal are integrated, a complementary purification mode can be achieved, concentrations of various pollutants in water bodies can be effectively reduced, and the water purification efficiency can be thus improved; the porous purification bricks are arranged in a canine tooth staggered arrangement mode, and water flows along a curve in the purification pond, so that not only is the water retention time of sewage in the purification pond prolonged, but also the water through quantity of the porous purification bricks is increased, and the water purification efficiency can be greatly improved.

Description

technical field [0001] The invention relates to a multi-connected ecological purification pool with canine teeth, which belongs to the technical field of water environment protection. Background technique [0002] With the rapid development of social economy and the further improvement of agricultural intensification, the contradiction among the agricultural ecological environment, natural resources and sustainable development of human beings has become increasingly prominent. In the agricultural production, the large-scale use of pesticides and chemical fertilizers and the unreasonable disposal of agricultural waste, these pollutants enter the downstream water body through rain erosion, surface runoff, and soil infiltration, making nitrogen, phosphorus, pesticides, and organic pollutants in the water body Seriously exceeded the standard, resulting in the continuous deterioration of the quality of the water body environment, which in turn caused a series of environmental pro...

AI Technical Summary

Problems solved by technology

However, since water pollutants often contain a variety of toxic substances, which have a destructive effect on aquatic plants and will seriously affect the absorption and degradation effect of aquatic plants on water pollutants, the efficiency of non-point source pollution removal using aquatic plants is limited.
