Abstract

The invention discloses a biological reaction well group and an underground water in-situ reinforced biological reaction wall and an arrangement method thereof. The biological reaction well groups areonly distributed at the boundary of the groundwater pollution range to be controlled and near the boundary of the groundwater pollution range. The first row of the biological reaction well group is distributed along the boundary line of the underground water pollution range to be controlled. The second row of the biological reaction well group is arranged towards the inner side of the boundary ofthe groundwater pollution range and is distributed on a perpendicular bisector which takes a connecting line of any two adjacent biological reaction wells in the first row as a bottom edge. The biological bacteria diffuse in the biological reaction well group at the boundary of the groundwater pollution range to form a closed biological reaction wall, carbon, nitrogen, phosphorus and other nutrient substances are regulated and controlled through the biological reaction well to continuously operate and maintain the biological reaction wall, and the purpose of controlling the groundwater pollution range not to be enlarged can be achieved without repairing the groundwater quality in a large range. The implementation method is simple, and the cost is controlled.

Description

technical field [0001] The invention relates to a group of wells and its groundwater in-situ enhanced biological reaction wall and a layout method, in particular to a biological reaction well group and its groundwater in-situ enhanced biological reaction wall and its layout method. Background technique [0002] Groundwater in-situ bioremediation technology is a remediation technology that converts pollutants into non-toxic substances through the biodegradation of organic pollutants in groundwater by microorganisms. Microbes digest organic pollutants, provide their own nutrients and energy, and decompose organic pollutants into carbon dioxide and water. In situ bioremediation of groundwater can be divided into two types: the first is to degrade organic pollutants by stimulating the growth and reproduction of indigenous microorganisms in the aquifer, and the stimulation of the growth of indigenous microorganisms is to inject electron donors into the aquifer (suitable for anaer...
