The Project Benefits Analysis on the Advanced Treatment of Heavy Metal Waste Water from Smelting Plant
The treatment engineering of heavey metal waste water from one lead-zinc smelting plant, we take it as an example, the process flow, the water quality and volume of inlet and outlet water, project investment, operation cost and benefit is analyzed and researched in this paper.When the project is completed, the economic benefit is three million two hundred eighty-nine thousand and eight hundred Yuan/a, the static payback time is 11.19 a, which is less than the 20a lifetime, the benefit-cost ratio is 1.43, which is larger than one;the waste water is reused in the production, the total emission reduction is 49.825 t/a, which can solve the social issue caused by environmental pollution completely.This type of project has a certain economic benefit, and more important, remarkable environmental and social benefit.
