Culturing device for microbes in river channels

Abstract

The invention discloses a culturing device for microbes in river channels. The culturing device comprises a frame which is formed by the connection of rigid materials, a biological filtering membrane, a plurality of floating balls, a plurality of microbial carriers and at least one aerator pipe, wherein the side of the biological filtering membrane is fixed to the edge of the frame so as to form a trough body of which the upper part is opened; the floating balls are fixed on the upper side edge of the frame; the microbial carriers are placed or fixed in the trough body formed by the biological filtering membrane; the aerator pipe penetrates through the lower part of the trough body formed by the biological filtering membrane, and the aerator pipe is positioned at an air hole formed in the trough body. The culturing device disclosed by the invention has the advantages that the microbial growth can be effectively promoted, and a better foundation is provided for the treatment of microbes in the river channels.

Description

technical field

[0001] The invention relates to the technical field of river course treatment equipment, in particular to a river course microorganism cultivation device. Background technique

[0002] River pollution is one of the environmental pollution problems that society is increasingly concerned about. For example, domestic garbage and domestic sewage, which are the main exogenous pollution sources, are discharged into the river, causing a large amount of organic waste and humic substances to be deposited on the bottom of the river, reducing the concentration of dissolved oxygen in the water and increasing the anaerobic environment at the bottom of the river. A large amount of organic matter fermented and rotted, producing excessive sulfide and harmful gases, resulting in the extinction of fish and shrimp, and subsequent sediment coverage made the bottom of the river channel solidify, enriched in nutrients, and eventually deteriorated water quality, black odor, and ser...
