Construction method for modifying and recycling waste slurry
The invention relates to the technical field of waste slurry, and discloses a waste slurry modification treatment recycling construction method which comprises the following steps: taking a set amount of waste slurry as a modified sample, and measuring an original state index value of the waste slurry; screening the waste slurry for a set time by using a slurry purification separator, measuring the sand content of the screened waste slurry, and stopping screening the waste slurry until the sand content is lower than the set sand content; a bentonite solution or clear water is added into the waste slurry, so that the specific gravity of the waste slurry is 1.05-1.15; strong acid salt or weak base salt is added into the waste mud, so that the pH value of the waste mud is 7-9; adding a cellulose solution into the waste slurry to enable the water loss, the mud cake thickness, the colloid rate and the viscosity of the waste slurry to meet set requirements; determining the ratio of the bentonite solution, the clear water, the strong acid salt, the weak base salt and the cellulose solution as a modification formula; the waste slurry generated by construction is modified according to the modification formula and then recycled.
本发明涉及废弃泥浆的技术领域，公开了废弃泥浆改性处理循环利用施工方法，包括取设定量的废弃泥浆作为改性样品，测定废弃泥浆的原始状态指标值；利用泥浆净化分离器筛分废弃泥浆设定时间，测定筛分后的废弃泥浆的含砂率，直至含砂率低于设定含砂率后，停止对废弃泥浆的筛分；往废弃泥浆中加入膨润土溶液或清水，以使废弃泥浆的比重在1.05～1.15之间；往废弃泥浆中加入强酸盐或弱碱盐，以使废弃泥浆的pH值在7～9之间；往废弃泥浆中加入纤维素溶液，以使废弃泥浆的失水量、泥皮厚度、胶体率以及黏度满足设定要求；确定膨润土溶液、清水、强酸盐、弱碱盐以及纤维素溶液的配比为改性配方；根据改性配方对施工产生的废弃泥浆进行改性后循环利用。
