Problems solved by technology

[0008] There are also many defects in this microbial enhancement technology. For example, the temperature, oxygen concentration, pH value, nutrition and other factors of the sewage also restrict the reproduction of microorganisms and the decomposition of organic matter.
At the same time, the newly added microorganisms take a long time to adapt to the new environment, and it is often difficult t

Example Embodiment

[0035] Such as figure 1 As shown, from the ecological environment (such as the contaminated ecological environment S1), the pollutant and microbial species are analyzed, and the most active dominant bacteria (SPPx) are sorted, and the professional targeted expansion is carried out in the laboratory. Verify its ability to degrade the decomposed pollutants and form a directional dominant strain or composite strain for ecological environmental bioremediation.

[0036] And according to the reproductive characteristics of dominant strains and environmental pollution characteristics, a selective medium for in-situ expansion is configured. The dominant bacteria and selective culture medium will be simultaneously put into the biological in-situ enhancement device for in-situ selective expansion. After the expansion, the high-density dominant bacteria will be regularly injected into the ecological environment to biodegrade pollutants.

[0037] Such as figure 2 As shown, the biological in...

Abstract

The invention discloses a microbial in-situ strengthening technology for bioremediation. By virtue of advanced microorganism sorting and selective culture technologies, dominant bacteria of native microorganisms in ecological environments (for example, soil and a water body) are sorted; and a selective culture medium for the dominant bacteria is specifically configured, is rapidly bred in a high-density microbial in-situ culture device, and then is fed to the ecological environments, so that the density of the dominant bacteria in the ecological environments is greatly improved; the degradation capacity of pollutants in the polluted ecological environments is correspondingly greatly improved; and the microbial in-situ strengthening technology is an effective, economical and reliable bioremediation technology.

Description

technical field [0001] The invention relates to the field of environmental protection, in particular to a microbial in-situ reinforcement technology and equipment for ecological environment bioremediation. technical background: [0002] With the development of domestic industrial production and industrial transfer, the pollution of the ecological environment (soil, water) has become more and more serious, and the pollution control and restoration of the ecological environment has also gradually received attention. [0003] As we all know, the pollution of the ecological environment is more complicated, some are heavy metal pollution, some are chemical pollution and so on. There are also various means of treatment, such as: chemical restoration treatment, physical restoration treatment, phytoremediation treatment, biological restoration treatment, etc. [0004] Among them, chemical and physical remediation treatment techniques use a large number of remediation agents or equi...
