重金属废水处理设备
炼铁、炼钢、轧钢等过程的冷却水及冲浇铸件、轧件的水污染性不大；洗涤水是污染物质较多的废水，如除尘、净化烟气的废水常含大量的悬浮物，需经沉淀后方可循环利用，但酸性废水及含重金属离子的水有污染。以各种化学状态或化学形态存在的重金属，在进入环境或生态系统后就会存留、积累和迁移，造成危害。如随废水排出的重金属，即使浓度小，也可在藻类和底泥中积累，被鱼和贝的体表吸附，产生食物链浓缩，从而造成公害。化学上根据金属的密度把金属分成重金属和轻金属。
冶炼废水处理方法：
化学沉淀法
　　化学沉淀法是使废水中呈溶解状态的重金属转变为不溶于水的重金属化合物的方法，包括中和沉淀法和硫化物沉淀法等。
　　在有色冶炼行业中应用较古老、较有效、较经典含重金属离子冶炼废水处理工艺是化学沉淀法。
化学沉淀法有以下几点：1、简单、**；2、可大批量处理；3、通过重量核算产物准确。工程中主要使用的沉淀药剂是氢氧化物与硫化物。

Heavy metal wastewater treatment equipment
Small iron and steel making and rolling process of the water pollution of cooling water and scouring casting, rolling; washing water is water pollution matter most, such as dust, flue gas purification wastewater often containing large amounts of suspended solids, the precipitation before recycling, but acidic wastewater containing heavy metal ions and water pollution. Heavy metals, which exist in various chemical or chemical forms, will be stored, accumulated and migrated after entering the environment or ecosystem, causing harm. For example, heavy metals discharged from wastewater, even with low concentration, can be accumulated in algae and sediment. They are adsorbed on the surface of fish and shells, resulting in food chain concentration, resulting in environmental pollution. Chemically, metals are divided into heavy metals and light metals according to the density of metals.
Smelting wastewater treatment methods:
Chemical precipitation method
Chemical precipitation is a way to transform heavy metals in dissolving state into insoluble heavy metal compounds, including neutralization precipitation and sulfide precipitation.
In the nonferrous smelting industry, the most ancient, most effective and most classic containing heavy metal ion smelting wastewater treatment process is the chemical precipitation method.
Chemical precipitation method has the following points: 1, simple, low price; 2, can be large batch processing; 3, through the weight calculation product accuracy. The main precipitating agents used in the project are hydroxides and sulfides.
