Environment-friendly cement preparation method
The invention belongs to the technical field of cement, and discloses an environment-friendly cement preparation method. The cement comprises the following components by weight: 10-20 parts of activated sludge, 30-60 parts of limestone, 20-40 parts of steel slag, 3-5 parts of a preservative, 1-3 parts of a dispersant, and 0.2-1 part of an adsorbent. The method has the following beneficial effects that the activated sludge is used as a part of raw material in the cement production process, so that the activated sludge can be recycled, waste is turned into wealth, and the requirement of clean production is met; the dispersing agent is added into the cement raw materials, so that the activated sludge and other raw materials can be mixed more sufficiently, and the cement quality can be improved; the sludge contains a certain amount of heavy metal, and the heavy metal can be dissolved out after being mixed in the cement, so that the heavy metal can be better solidified in the cement finished product by adopting the adsorbent, and secondary pollution is avoided.
本发明属于水泥技术领域，公开了一种环保型水泥制备方法，水泥由以下重量份组成，活性污泥10‑20份、石灰石30‑60份、钢渣20‑40份、防腐剂3‑5份、分散剂1～3份、吸附剂0.2～1份。具有以下有益效果：将活性污泥作为水泥生产过程中一部分原料，可对活性污泥进行资源化利用，变废为宝，负荷清洁生产的要求；在水泥原料中添加分散剂，可使活性污泥与其他原料混合更为充分，有利于提高水泥质量；由于污泥中含有一定量的重金属，混合在水泥中可能发生溶出，采用吸附剂可更好的将重金属固化在水泥成品中，避免产生二次污染。
