研究了湿法炼锌黄钾铁矾渣除铁工艺的中和剂，分析了碳酸氢铵和焙砂作为沉矾中和剂的优缺点，指出用除去铁酸锌的焙砂作中和剂，可降低成本，减少渣含锌。

The pollution of As results from the copper deposits, the lead-zinc deposits and limonite, and from their exploitation; the pollution of Cd is related to lead-zinc deposits, the exploitation, and agricultural irrigation with waste water; the pollution of Pb and Zn are mostly ascribed to the lead-zinc deposits and related exploitation.

As元素污染的主要原因是铜矿、铅锌矿褐铁矿矿床及其开发；Cd元素的污染与铅锌矿床及其开发，以及农业污灌有关；Pb、Zn元素的污染与铅锌矿床及其开发密不可分。

The contents of organic matter, total nitrogen, phosphorus, iron, manganese, copper, zinc can be increased, and the contents of hydrolizable nitrogen and their forms , Fe-P, Al-P, Ca〓-P, all organic P forms, exchangeable and organic iron, manganese, copper, zinc are increased obviously in long-term application organic manure soil. Not only the contents of soil readily oxidizable carbon, humic acid, fuluic acid, and HA/FA value are increased and Kos value decreased but also the available nitrogen, phosphorus, iron, manganese, copper, zinc are kept more high level in the organic manure soils. Long-term mulching straw has similar role with organic manure for soil nutrient except for decreasing total phosphorus, available P, N and Ca〓-P, but its fertilizer efficiency is not better than organic manure.
