Environment evaluation method of stone coal vanadium-extracting solid waste

Abstract

The invention relates to an environment evaluation method of stone coal vanadium-extracting solid waste. The environment evaluation method comprises the evaluation steps of step 1, determination of water content of the stone coal vanadium-extracting solid waste and analysis of average particle diameter of the stone coal vanadium-extracting solid waste; step 2, survey of annual average wind speed u of a stone coal vanadium-extracting solid waste storage yard and area S of the stone coal vanadium-extracting solid waste storage yard; step 3, calculation of dusting amount Qp of the stone coal vanadium-extracting solid waste; step 4, forecast of dust concentration in a downwind direction by adopting an atmosphere Screen 3 estimation mode; step 5, leaching toxicity analysis; step 6, evaluation index selection; and step 7, fuzzy comprehensive evaluation. The environment evaluation method disclosed by the invention has the characteristics of simpleness and convenience in operation and high efficiency, not only can pollution degree of the stone coal vanadium-extracting solid waste on environment be quantitatively analyzed, but also the influence of stone coal vanadium-extracting solid waste storage environment on atmosphere and water body can be objectively and accurately analyzed, and reliable basis is provided for treating the stone coal vanadium-extracting solid waste.

Description

technical field [0001] The invention belongs to the technical field of environmental assessment methods, and in particular relates to an environmental assessment method for vanadium extraction solid waste from stone coal. Background technique [0002] The development of industrial and mining enterprises and the acceleration of urbanization have promoted the progress of society and the improvement of human living standards, but at the same time, a large amount of pollutants produced in the process of production and life have also aggravated environmental problems. With the improvement of people's awareness of environmental protection, the state and the government have strengthened their efforts to control the environment, and corresponding laws, regulations and policies have been promulgated one after another, and environmental problems have been alleviated to a certain extent. Researchers at home and abroad spend a lot of manpower and material resources on environmental gove...

AI Technical Summary

Problems solved by technology

It is mainly a simple qualitative evaluation of the amount of solid waste generated from vanadium extraction from stone coal and the impact of solid waste from vanadium extraction from stone coal on the environment. The subjective factors are relatively large, and the particularity of solid waste from vanadium extraction from stone coal is not considered.
