Embodiment 1

[0040] Taking the black and odorous water body of a polluted river in Shenzhen as the restoration object, the main indicators are: the total number of heterotrophic bacteria is 159500 / g (calculated as dry mud), and the number of antisulfurizing bacteria is 11975 / g (calculated as dry mud) ), the biodegradability G value is 11 (10 - 3 kg·kg -1 h -1 ), the dissolved oxygen (DO) of the overlying water body is 2.2mg / L, the moisture content of the sediment is 41.8%, and the organic matter (TOC) content of the sediment is 3.16%.

[0041] The experiment uses a 60cm×35cm×20cm uncovered plexiglass tank as the experimental device, laying 1.5cm of bottom mud with a mass of 1500g, and adding 4L of tap water as the overlying water body.

[0042] The preparation method of the microbial growth stimulator that present embodiment adopts is as follows:

[0043] S11, preparing organic acid solution: citric acid, tartaric acid, oxalic acid, ethylenediaminetetraacetic acid and citric acid are p...

[0062] Taking the black and odorous water body of a polluted river in Shenzhen as the restoration object, the main indicators are: the total number of heterotrophic bacteria is 159500 / g (calculated as dry mud), and the number of antisulfurizing bacteria is 11975 / g (calculated as dry mud) ), the biodegradability G value is 11 (10 - 3 kg·kg -1 h -1 ), the dissolved oxygen (DO) of the overlying water body is 2.2mg / L, the moisture content of the sediment is 41.8%, and the organic matter (TOC) content of the sediment is 3.16%.

[0063] A 60cm×35cm×20cm uncovered plexiglass tank was used as the experimental device in the experiment, and 1.8cm of bottom mud was laid, with a mass of 1680g, and 4L of tap water was added as the overlying water body.

[0064] The preparation method of the microbial growth stimulator that present embodiment adopts is as follows:

[0065] S11, preparing organic acid solution: citric acid, tartaric acid, oxalic acid, ethylenediaminetetraacetic acid and ...

Abstract

The invention discloses a microorganism growth stimulant and a preparation method. The microorganism growth stimulant is used for restoring black and odorous water bodies. The microorganism growth stimulant consists of an oxidant and a stimulant; the oxidant is one or two of potassium peroxide or potassium nitrate; the stimulant comprises components such as organic acid, microorganism carbon source, vitamins, inorganic salt, trace elements and the like. The microorganism growth stimulant provided by the invention is fed to a black and odorous water body, so that the micro-ecological system ofthe black and odorous water body can be developed in the direction beneficial to the pollution restoration of the black and odorous water body, the diversity of the microorganism flora of the black and odorous water body can be improved; the pollutant degradation rate of the restored water body is significantly higher than that of the water body without the stimulant; the influence of the bottom mud pollution for the overlying water body can be fundamentally solved, and an excellent solution can be provided for controlling the black and odorous water body.

Description

technical field [0001] The invention belongs to the technical field of water environment restoration, and in particular relates to a microbial growth stimulator and a preparation method thereof. Background technique [0002] In recent years, bioremediation technology, which has received increasing attention in the restoration of polluted environments, refers to the use of metabolic activities of certain organisms (such as plants, animals, microorganisms, etc.) to remove pollutants in the environment and make parts of the polluted environment Or the process of restoring all functions. Compared with traditional physical and chemical restoration methods, bioremediation has the advantages of low cost, no secondary pollution or transfer of pollutants, damage to the original ecosystem, small negative impact on the environment, and good restoration effect. An important means and technology of environmental restoration and governance. [0003] Microbial remediation technology is a...
