随着资源开发和工业生产的迅速发展,工业废渣的排放日趋增加.这些废渣如不处理和利用,既制约生产发展,又造成环摸污染。因此,搞好废渣利用是面临的一个重要课题。下面就河南工业废渣利用作一初步探讨。一、河南工业废渣现状特点及发展趋势工业废渣排放形式取决于矿产的种类和工矿生产采取的手段。河南矿产资源丰富,种类多,现已发现主要矿产近百种,占全国的三分之二,名列前茅的有几十种,尤以煤、有色金属居多.所以,河南煤炭、火电、冶金等工业较发达.煤炭产量居全
With the rapid development of resource development and industrial production, the discharge of industrial waste slag is increasing. If these waste slags are not handled and utilized, they will not only restrict the development of production, but also cause environmental pollution. Therefore, the use of waste residue is an important issue. The following is a preliminary discussion on the utilization of industrial waste in Henan. I. Current status and development trend of industrial waste residue in Henan The industrial waste residue discharge form depends on the type of minerals and the means adopted for industrial and mining production. Henan has rich mineral resources and many types. It has now discovered nearly 100 kinds of major minerals, accounting for two-thirds of the country’s total. Dozens of them are among the top, especially coal and non-ferrous metals. Therefore, Henan Coal, thermal power, metallurgy and other industries More developed. Coal production ranks
