Method for preparing unfired water permeable brick from river and lake bottom mud
A method for preparing unfired water permeable bricks from river and lake bottom mud comprises the following steps: (1) raw material selection: selecting bottom mud, red mud, slag, quick lime and fibers as raw materials; (2) pretreating the raw materials; (3) mixing and stirring: uniformly stirring the raw materials to obtain a mixed material; (4) performing static pressure molding, namely performing compression molding on the mixed material in a mold; (5) maintaining the green brick; curing the water permeable brick in a steam curing manner to obtain the water permeable brick; (6) secondary microbial adsorption; and washing the prepared water permeable brick with water at room temperature, then putting the water permeable brick in a bacterial suspension, and standing so that microorganisms are adsorbed and biofilm-formed. The brick is prepared through static pressure molding, energy consumption is reduced, generated pollution is avoided, the prepared unfired water permeable brick carries microorganisms capable of treating pollutants in surface runoff, cyclic utilization of waste is achieved, and the water permeable rate is high.
一种利用河湖底泥制备免烧透水砖的方法，包括如下步骤:（1）原料选取，选取底泥、赤泥、矿渣、生石灰和纤维为原料；（2）原料预处理；（3）混合搅拌，将原料均匀搅拌得到混合物料；（4）静压成型，将混合物料在模具中压制成型；（5）砖胚养护；将透水砖采用蒸汽养护的方式进行养护，制得透水砖；（6）二次微生物吸附；将制得的透水砖在室温用水冲洗干净，然后放在菌悬液中，静置，使微生物吸附挂膜。本发明通过静压成型制砖，降低了耗能，避免了产生的污染，制备的免烧透水砖携带能够处理地表径流中污染物的微生物，实现了废弃物的循环利用，透水率高。
