Composite sludge curing agent
The invention relates to the field of sludge treatment, in particular to a composite sludge curing agent. The composite sludge curing agent is prepared from the following raw materials in parts by weight: 30-40 parts of fly ash, 15-20 parts of citric acid residue, 11-13 parts of calcium bentonite, 58 parts of cement, 0.5-0.8 part of carbide slag, 0.3-0.5 part of a polycarboxylate superplasticizer and 0.12-0.15 part of a heavy metal chelating agent. The composite sludge curing agent provided by the invention not only can improve the strength of sludge, but also can effectively absorb water in the sludge in a short time, and has a better heavy metal adsorption effect, the sludge treated by the composite sludge curing agent can be used on a road bed, the road building cost is reduced, meanwhile, the composite sludge curing agent is relatively environment-friendly, and secondary pollution of the sludge is effectively prevented; the fly ash, the citric acid residues and other wastes are used as main raw materials, the doping amount is small during sludge consolidation treatment, the cost is low, and large-scale popularization is facilitated.
本发明涉及淤泥处理领域，特别是一种复合淤泥固化剂，按重量份数计算，其原料包括：粉煤灰30~40份，柠檬酸渣15~20份，钙基膨润土11~13份，水泥5~8份，电石渣0.5~0.8份，聚羧酸减水剂0.3~0.5份，重金属螯合剂0.12~0.15份。本发明提供的复合淤泥固化剂既能提高淤泥强度，又能在短期内有效吸收淤泥中水，且吸附重金属效果更好，经本复合淤泥固化剂处理后的淤泥能够在道路路基上使用，降低筑路成本，同时对环境较为友好，有效防止淤泥的二次污染；以粉煤灰和柠檬酸渣等废弃物为主要原料，在进行淤泥固结处理是的掺加量少，成本低廉，有利于大规模推广。
