Alkali-modified steel slag adsorption phosphorus removal filler as well as preparation method and application thereof
The preparation method comprises the following steps: carrying out alkali modification pretreatment on steel slag powder, mixing the pretreated steel slag powder with cement and diatomite according to a ratio of 60.9%: 26.1%: 13.0%, carrying out granulation, and carrying out maintenance for seven days to form a finished product, and the adsorption capacity of the finished product is 1.98 times that of steel slag with the same volume. According to the method, the industrial waste steel slag can be recycled, the purpose of treating waste with waste is achieved, and the method is a great innovative measure for environmental treatment. The modified steel slag filler disclosed by the invention can be used for carrying out chemical precipitation and ligand exchange on phosphorus in rural sewage through calcium phosphate (Ca-PO4) precipitation. As calcination is not carried out and the raw materials are low in price, the cost can be further reduced, and compared with other fillers, the filler has higher competitiveness.
本发明公开了一种碱改性钢渣吸附除磷填料及其制备方法和应用，制备方法包括如下步骤：将钢渣粉末进行碱改性预处理后，与水泥、硅藻土按60.9％：26.1％：13.0％的比例混合造粒，养护七天后形成成品，吸附能力是同体积钢渣的1.98倍。该发明可以对工业废物钢渣进行资源化利用，达到以废治废的目的，是环境治理的一大创新性举措。本发明所述的改性钢渣填料可以通过磷酸钙(Ca‑PO4)沉淀对农村污水中磷进行化学沉淀和配位体交换。由于未进行煅烧且原料价格低廉，可以进一步压缩成本，相较于其他填料具有更大的竞争力。
