Sludge curing agent and production method thereof
The invention discloses a sludge curing agent and a production method thereof. The sludge curing agent is prepared from the following raw materials in parts by weight: 60-100 parts of sulphoaluminatecement, 10-40 parts of Portland cement, 40-70 parts of superfine slag micro-powder, 20-40 parts of fly ash, 2-10 parts of dispersible latex powder, 2-10 parts of sodium silicate, 4-12 parts of hydroxyl calcium phosphate and 4-12 parts of modified nano montmorillonite. The preparation method comprises the following steps: grinding the sulphoaluminate cement, the Portland cement, the fly ash, the sodium silicate and the hydroxyl calcium phosphate, performing sieving with a 200-300-mesh sieve, adding the superfine slag micro-powder, the dispersible latex powder and the modified nano montmorillonite, and performing sufficient and uniform mixing to obtain a finished product. The sludge curing agent provided by the invention has strong dehydration property, and can effectively adsorb heavy metals in sludge and fix the heavy metals, so that the cured sludge can be recycled.
本发明公开了一种淤泥固化剂及其生产方法，所述淤泥固化剂由以下重量份数原料制成：硫铝酸盐水泥60‑100份、硅酸盐水泥10‑40份、超细矿渣微粉40‑70份、粉煤灰20‑40份、可分散乳胶粉2‑10份、硅酸钠2‑10份、羟基磷酸钙4‑12份、改性纳米蒙脱石4‑12份；对硫铝酸盐水泥、硅酸盐水泥、粉煤灰、硅酸钠、羟基磷酸钙进行研磨，并通过200‑300目筛，再加入超细矿渣微粉、可分散乳胶粉、改性纳米蒙脱石充分混合均匀即得到成品。本发明的淤泥固化剂具有较强的脱水性，同时可以有效地吸附淤泥中的重金属并将其固定下来，使固化后的淤泥可以重复利用。
