Abstract

The invention provides a method for collecting acid water in a waste dump. The method comprises the following steps that a retaining dam is arranged on the earth surface of the waste dump, and the acid water flowing out of the waste dump is intercepted on the earth surface for the first time; a seepage interception pumping well is arranged at the downstream of the retaining dam, and the acidic water permeating into the underground is secondarily intercepted underground; the acidic water collected in the seepage interception pumping well is conveyed to an upstream retaining dam or a surface water treatment plant through a water suction pump arranged in the seepage interception pumping well; a water quality observation well is arranged at the downstream of the seepage interception pumping well, whether the water is polluted water is judged by pumping underground water in the water quality observation well, and the water quality condition of the position of the water quality observation well can be improved by increasing the number of upstream seepage interception pumping wells under the condition of pollution. According to the method for collecting the acidic water in the waste dump, the investment is low, the earth surface is easy to implement, the construction is convenient, and the effect of detecting and treating the acidic water is very convenient.

Description

technical field [0001] The invention relates to the field of environmental protection, in particular to a method for collecting and storing sewage, in particular to a method for collecting acidic water from dump sites. Background technique [0002] When mining sulfide deposits, the sulfide content in the ore body and surrounding rocks is generally high. When the sulfur content exceeds 1.5% to 2.0%, the sulfide in the strippings or waste rocks piled up in the dump site is affected by atmospheric precipitation and surface water. After leaching, scouring, and erosion, a series of chemical reactions may often occur under the joint action of oxygen and water. The pH value of groundwater and surface water will decrease significantly after flowing through the rock and soil of the dump site, forming an acidic acidity that is harmful to the natural environment. sewage. It must be collected and treated to prevent ecological environment pollution. [0003] Under the background of glo...
