High-water-content sludge resource utilization method
The invention discloses a high-water-content sludge resource utilization method which comprises the following steps: step SS1, taking a certain amount of high-water-content sludge, and adding a flocculating agent into the high-water-content sludge; step SS2, after a flocculation phenomenon is generated in the sludge and the sludge is stabilized, pumping supernatant liquid by utilizing water pumping equipment; step SS3, putting the water absorbent wrapped by the geotextile into the sludge from which the supernatant is pumped to absorb water until the sludge cannot be further dehydrated; and step SS4, adding a cementing material into the dewatered sludge, and fully stirring to prepare the filling brick or roadbed filling material. The method overcomes the defects of long time consumption, high cost and insufficient treatment of traditional high-water-content sludge treatment, and has the characteristics of low cost, high speed, good economic benefit, on-site treatment and the like.
本发明公开了一种高含水率淤泥资源化利用的方法，包括如下步骤：步骤SS1：取一定量的高含水率淤泥，向其中加入絮凝剂；步骤SS2：待淤泥中产生絮凝现象并达到稳定后，利用抽水设备，抽去上层清液；步骤SS3：将被土工布包裹的吸水剂投入到抽去所述上层清液的淤泥中吸水，直至淤泥已无法进一步脱水；步骤SS4：向脱水处理后的淤泥中加入胶凝材料，充分搅拌，制备得到填充砖或路基填筑材料。本发明克服了传统高含水率淤泥处理耗时久、成本高、处理不充分的缺点，具有成本低、速度快、经济效益好，可就地处理等特点。
