Efficient silt-eliminating flora and compound indigenous microorganism in-situ silt elimination technology

Abstract

The invention discloses an efficient silt-eliminating flora and compound indigenous microorganism in-situ silt elimination technology. The efficient silt-eliminating flora and compound indigenous microorganism in-situ silt elimination technology comprises the following steps: 1) cultivating a silt-eliminating flora; 2) preparing a viable bacterium preparation; 3) cultivating compound indigenous microorganisms; 4) carrying out ultrasonic microwave treatment; 5) carrying out in-situ silt elimination; diluting the viable bacterium preparation obtained by step 2) for 3 times by utilizing de-ionized water; adding the viable bacterium preparation into a mixture obtained by step 4) and uniformly mixing; putting a mixture into the bottom of a river channel to be subjected to silt elimination. Theefficient silt-eliminating flora and compound indigenous microorganism in-situ silt elimination technology has a good silt elimination effect; the in-situ silt elimination is carried out by utilizingplaster prepared from the viable bacterium preparation prepared from the silt-eliminating flora, and the compound indigenous microorganisms, and silt does not need to be fished out for treatment, so that the labor intensity is reduced; meanwhile, the technology is environmentally friendly and has a wide market prospect.

Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to an in-situ desilting technology of high-efficiency desilting bacteria group and compound indigenous microorganisms. Background technique [0002] With the continuous development of science and technology, the construction of water conservancy and hydropower projects in my country is also increasing. In the operation, maintenance and management of these projects, river siltation has become a prominent problem. Serious siltation has occurred in many rivers, which not only reduces the navigation and flood discharge capacity of the river, but also damages the ecological function of the river to a certain extent. [0003] There are many reasons for river siltation. For example, the mutual conversion of sediment caused by river dynamics; the gates of many rivers are closed all year round, which damages the natural flow of the river to varying degrees and weakens the se...

Problems solved by technology

However, the traditional river desilting needs to remove the silt for treatment, which increases the treatment process and labor intensity. At the same time, chemical agents are usually used to desilt the river, which is not friendly to the environment.
