Concrete module for encapsulating microbial agent in river channel

Abstract

The invention provides a concrete module for encapsulating a microbial agent in a river channel. The concrete module comprises a pouring body, a plurality of biological bacterial agent packing layersand a plurality of permeation packing layers; the pouring body is provided with an internal cavity and a pouring layer surrounding the cavity; the interior cavity of the pouring body is sequentially filled with the biological bacterial agent packing layers and the permeation packing layers layer by layer; at least one side surface pouring layer of the pouring body is embedded with honeycomb-shapedfiller and penetration filler; and a water body can enter the interior cavity of the pouring body through the honeycomb-shaped filler and penetration filler embedded in the side surface pouring layer, wherein the biological bacterial agent filler layer comprises a microbial agent, carbon fiber ecological grass and permeation filler, and the permeation filler layer comprises permeation filler. Theconcrete module disclosed by the invention can ensure that a water body of flowing water permeates into the filler layer of the biological bacterial agent, so that the biological bacterial agent canbe used for restoration and prevention of the polluted river channel; and the concrete module can also prevent loss of the biological bacterial agent through the penetration filler layers.

Description

Technical field [0001] The invention belongs to the technical field of civil engineering materials, and specifically relates to a concrete module for encapsulating microbial agents applied to river channels. Background technique [0002] At present, according to the different principles of control methods, the treatment methods of polluted water bodies can be divided into physical methods, chemical methods and biological methods. The main physical control methods are the dredging method and the covering method. The advantage is that the effect is quick, but the amount of work is large, the cost is high, and it is destructive to the benthic ecosystem. The dredging method also needs to consider the issue of sediment placement sites. The principle of chemical method is that chemical reagents and pollutants undergo oxidation, reduction, precipitation, polymerization and other reactions, so that pollutants are separated from the bottom sludge or converted into a low pollution or non-p...

Problems solved by technology

Jiang Hua used pulverized coal, oat stalks, fir, etc. as raw materials to make substrate carriers and added them to the river channel, and then added compound bacteria to repair the river channel sediment (application number 201310388670.0), realizing the resource utilization of waste. It will cause secondary pollution, but when adding complex bacteria, it is directly put into water, the impact and dilution of water flow will reduce the microorganisms on the carrier, resulting in a certain degree of waste
