Anaerobic bacteria harvesting method, anaerobic bacteria harvesting device and storage device

Abstract

The invention relates to an anaerobic bacteria harvesting method, an anaerobic bacteria harvesting device and a storage device. The anaerobic bacteria harvesting device comprises anaerobic gas supplyequipment, an anaerobic gas conveying system and the storage device; a first pipeline is detachably connected with a gas of the storage device and is used for charging anaerobic compressed gas into the storage device from anaerobic gas supply equipment before collection; the first pipeline can also be detachably connected with an air bag pump controller during collection; the air bag pump controller communicates with a gas inlet of the air bag pump through a second pipeline; the first pipeline can also be detachably connected with a gas inlet / outlet of the storage device during filling; and athird pipeline can be arranged in underground water after being detached from the air bag pump, so that the whole-process anaerobic environment can be ensured and activity of bacteria can be maintained while collection and transplantation of protogenous dehalogenation anaerobic bacteria can be realized. In the underground environment polluted by chlorine-containing organic matter, the transplantedstrains realize high-efficiency degradation of chlorine-containing organic pollutants in soil and underground water by utilizing natural flora, accelerate in-situ bioremediation efficiency of the whole site, and improve the remediation effect.

Description

technical field [0001] The invention relates to the technical field of fungi harvesting and planting, in particular to an anaerobic bacteria harvesting and planting method, device and bacteria storage device, which are used to realize the enhanced in-situ bioremediation technology (Enhanced In-Situ Bioremediation, EIB) for repairing groundwater contaminated by chlorine-containing organic substances. ) non-territorial migration and application of dominant dehalogenated bacteria. Background technique [0002] With the rapid development of industry, the problem of man-made environmental pollution is becoming more and more serious, which has attracted extensive attention from the government, enterprises and the general public. The investigation of soil and groundwater pollution is also particularly important. [0003] Among the various pollutants of soil pollution and groundwater pollution, the impact of chlorinated organic pollutants on soil and groundwater is relatively comple...

Problems solved by technology

If the former is used, it will take a long time to wait for the Dhc. bacteria to reproduce and domesticate naturally in the site; and it cannot meet the needs of the project progress, and the degradation effect is also uncontrollable

If the latter is adopted, it may be subject to customs restrictions on the transportation and quarantine of bacterial strains, and concerns about the impact of foreign strains on the ecological balance of local strains
