Ecological water square module used for black and stink water body treatment and water quality improvement

Abstract

The invention discloses an ecological water square module used for black and stink water body treatment and water quality improvement. The ecological water square module used for black and stink waterbody treatment and water quality improvement comprises submerged plants, a biological filling material, a net-shaped framework, and light sources; the submerged plants are used for adsorption on nitrogen and phosphor eutrophication salts in precipitated bottom sludge and suspended in water body; the artificial light sources are used for promoting photosynthesis of water plants, promoting submerged plant growth and breeding, and improving water body transparency and treatment effect; the biological filling material is inoculated with a microbial agent to realize adsorption, conversion, and degradation of precipitated bottom sludge and pollutants suspended in water body with microbes, eliminate water body black color and stink smell, establish a water body ecological system, provide aquatic animals with an inhabit environment, accelerate recovery of water environment capacity, and realize water body self cleaning.

Description

technical field [0001] The invention relates to the technical field of ecological environment engineering, and the technical field of ecological reconstruction and restoration of natural and artificial rivers and lakes, in particular to an ecological level square module for controlling black and odorous water bodies and improving water quality. Background technique [0002] With the rapid development of industry and the acceleration of urbanization, the pollution of lakes, rivers and other water bodies is increasing day by day. A large number of water bodies in cities have become black, smelly or eutrophic. The shortage of water resources has gradually become an important problem to be solved in modern society. . [0003] Submerged plants absorb nutrients (such as nitrogen, phosphorus, etc.) in the water body during their growth, so they play an important role in the aquatic ecosystem. For eutrophic rivers, lakes, and wetlands, the method of harvesting submerged plants in a...

Problems solved by technology

[0004] However, the current technology of submerged plants to purify rivers has the following problems: 1) Submerged plants are not suitable for growing on hardened river beds; 2) Plant roots are easily damaged by benthic aquatic animals and water flow; 3) In heavily polluted urban rivers, high levels of Suspended solids will not only significantly reduce the transparency of water bodies, but also adhere to the surface of submerged plants. Limited by light, they will seriously affect the photosynthesis of submerged plants, inhibit the normal growth and reproduction of submerged plants, and even cause the plants to die and rot. , thus affecting the treatment effect of submerged plants and causing secondary pollution
