[0004] How to restore the original ecological structure of rivers and lakes? At present, traditional urban river management at home and abroad mainly adopts physical and chemical methods. Although these methods are effective, the effect will deteriorate over time, consuming a lot of human and financial resources.
And chemical methods are easy to cause secondary pollution to the environment, so it is not suitable to use

Embodiment 3

[0083] In river channel management, overflow dams are generally built on the river channel, divided into several sections (each section is about 200-500m in length), and a 0.3-0.5-meter-high long-term hollow biological filler is added above the overflow dam to control the water flow velocity. Increase the retention time of each section of the water body and improve the treatment efficiency. The biological filler with holes in the middle is used to maintain a certain elevation difference between each section. When the water is full from one section and flows into the other section, a small waterfall is formed, which plays the role of natural aeration and oxygenation. Each section of the river uses non-fired hollow bricks to create the slope of the river, and the mounds, stone mounds, and caves of the river are constructed to complicate the micro-environment of the river, which is beneficial to the restoration of the river and the purification of the water body.

Abstract

The invention relates to a multi-channel efficient biological filler. The multi-channel efficient biological filler containing a multi-channel shape is prepared as follows: screening of an efficient dephosphorization denitrogenation bacteria strain, construction of a bacteria strain for efficient degradation of organic pollutants by genetic engineering, compounding of fly ash, silicate, clay, and incorporation of a hardening strength increasing admixture. The product is placed in river channels and lake and pool bottoms, or is used as a wetland substrate, fly ash, volcano rock and other materials in the product can absorb nitrogen and phosphorus, trace organic pollutants and other water bottom or pool bottom harmful substances, and supplement water trace elements, microorganisms in the product are capable of degrading the absorbed materials, removing water COD (chemical oxygen demand), ammonia nitrogen, total nitrogen, total phosphorus and turbidity, improving water pH, improving water transparency, and playing good effects on water quality purification of rivers, lakes, wetlands and other water bodies.

Description

technical field [0001] The invention relates to the integrated technology of physics, chemistry and biology in the fields of lake, river course and wetland restoration. More specifically, it is a multi-channel shaped biofiller and its application. Background technique [0002] In recent years, with the development of industry and the concentration of population, people's pollution of rivers and lakes has become more and more serious, which is manifested in a large number of endocrine disruptors ( EndocrineDisruptingChemicals, EDCs), anionic surfactants (LinearAlkylbenzeneSulphonates, LAS), medicines and personal care products (PharmaceuticalandPersonalCareProducts, PPCPs) are directly discharged into rivers and lakes, causing water pollution and eutrophication. At the same time, a large number of chemical industrial parks have emerged in various places, and the wastewater produced by chemical industrial parks contains a large amount of pollutants such as polycyclic aromatic...
