Soil/underground water integrated injection system and single-source, double-source and mixed micro-nano bubble liquid injection method thereof

Abstract

The invention relates to a soil / underground water integrated injection system and a single-source, double-source and mixed micro-nano bubble liquid injection method thereof. A medicament configurationunit, an air supply unit and a water supply unit, which are controllably connected through different channels, are arranged in a container body and controllably connected to an injection buffer and an injection distributor, and a controller is used for controlling opening and closing of all the channels under different requirements to complete injection operation of water / medicament / air, micro-nano bubble water and mixed micro-nano bubble liquid. The system is mainly used for repairing polluted sites and underground water, can be applied to polluted sites of various geologies, has a strong medicament mixing performance, can perform various remediation operations on the polluted regions such as liquid injection, liquid-gas injection, aeration, and the like, can dredge an injection well, issuitable for polluted sites of various geologies , has the advantages of mobility, efficiency, long service life, high safety in construction process, good construction and operation environment, andthus has a good application prospect.

Description

technical field [0001] The present invention relates to the technical field of regeneration of polluted soil and treatment of water, waste water, sewage or sludge, in particular to a soil / groundwater integrated injection system and its single-source, Dual-source and mixed micro-nano bubble liquid injection method. Background technique [0002] In recent decades, with the rapid development of the domestic economy, the extensive economic growth mode, the weak awareness of environmental protection from all walks of life, the lack of corporate environmental protection equipment and capital investment, improper environmental protection management, leakage, leakage, and random stacking in the production process Factors such as random dumping and leakage accidents have caused serious environmental pollution problems left over from history and accumulated in various regions while developing. At present, with the optimization and adjustment of the industrial structure and the accele...

AI Technical Summary

Problems solved by technology

This invention is mainly aimed at the aeration treatment of black and odorous water bodies on the ground, and provides a method for preparing supersaturated dissolved oxygen water, but there is no special design for how to inject oxygen-rich bubbles and solutions into complex underground environments , and the whole system cannot be directly applied to the remediation and disposal of site soil / groundwater
