Method for making bricks from sludge
The invention relates to a method for making bricks from sludge, which comprises the following steps: S01, taking a certain amount of sludge, and equally dividing the sludge into two parts; S02, adding the sludge into a stirrer for stirring; S03, equally dividing the stirred sludge into two parts, incinerating the first part of sludge to obtain sludge incineration ash, crushing waste bricks to form brick residues, and mixing the brick residues and the sludge incineration ash to form an additive; S04, adding water into the second part of sludge, stirring, adding a pH regulator, and regulating the pH regulator to 12 or above; S05, putting the sludge obtained in the step S03 into a sedimentation tank for performing standing, adding a curing agent, and then stirring and performing standing; S06, after standing, transferring the settled sludge into a dewatering tank, dewatering in the dewatering tank, and then performing standing; S07, after standing, feeding the sludge into a mixing tank,adding the additive prepared in the step S02, SiO2, Al2O3 and Fe2O3, then mixing, stirring, feeding into an extruder, fully mixing, then feeding into an aging tank, and aging for 48 hours; and S08, feeding the aged brick making pug into a blank making workshop.
本发明为一种污泥制砖的方法，包括如下步骤，S01‑取一定量的污泥，均分成两份；S02‑将污泥加入到搅拌机中进行搅拌；S03‑将搅拌后的污泥均分成两份，将第一份污泥进行焚烧，获得污泥焚烧灰，同时将废弃砖块进行破碎，形成砖渣，将砖渣、污泥焚烧灰进行混合形成添加剂；S04‑将第二份污泥加水进行搅拌，加入PH调节剂，将PH调节剂调整至12或12以上；S05‑将S03中获得的污泥投入到沉淀池中进行静置，并加入固化剂后搅拌静置；S06‑静置后对沉淀后的污泥转移至脱水池内，脱水池内进行脱水，随后静置；S07‑静置后将污泥送入混合池，加入S02制得的添加剂以及SiO2、Al2O3、Fe2O3，随后混合搅拌送入挤出机充分混合，再送入陈化池，陈化48小时；S08‑陈化后的制砖泥料送进制坯车间。
