A dog-tooth split multi-connected ecological purification pool

Abstract

The invention discloses a canine-tooth combined multi-connected ecological purification pond, which comprises a purification pond, a plurality of porous purification bricks, aquatic plants, and a plurality of retaining bars. Bars, multiple bars divide the bottom of the purification pool into several strip-shaped areas; aquatic plants and porous purification bricks are fixed at intervals between multiple bars, and multiple porous purification bricks are arranged at intervals between adjacent bars. Two adjacent rows of porous purification bricks are arranged in a staggered manner. The invention integrates the three water purification means of plant absorption, microbial degradation and photocatalytic removal to form a complementary purification method, which can effectively reduce the concentration of various pollutants in the water body and improve water purification efficiency; porous purification bricks Adopting the dog-tooth staggered arrangement, the water flow curves in the purification tank, which not only increases the hydraulic retention time of sewage in the purification tank, but also increases the water flow in the porous purification bricks, which greatly improves the water purification efficiency.

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.
