The invention discloses a sludge-to-brick method and process and a brick making process system. According to the method, raw material sludge is subjected to ozone treatment, and phosphorus in the sludge is adsorbed by adding an adsorbent; sludge drying is completed through a multi-stage drying process; heavy metal treatment is performed on the dried sludge; a strain is added into the dried sludge for fermentation, and a deodorant is added for deodorization after the fermentation process; the deodorized sludge is mixed and stirred with an additive, and the mixture is fed into an aging tank for aging; and firing is performed after blank making, color mixing and drying. According to the invention, ozone is used for oxidizing sludge to remove organic matters in the sludge, then an adsorbent is used for adsorbing phosphorus in the sludge, two-stage drying is adopted, waste heat is fully utilized, resource waste and energy consumption are reduced, and after the sludge is dried, the sludge is further fermented and deodorized, so that the quality of the sludge blank is effectively improved while the energy is saved so as to achieve the durable prepared process brick.
本发明公开了一种污泥制砖方法工艺及制砖工艺系统，首先对原料污泥进行臭氧处理，并且通过添加吸附剂吸附出污泥中的磷；再经过多级干化工艺完成污泥干化；对干化后的污泥进行重金属处理；向干化后的污泥中投加菌种，进行发酵，并在发酵工艺后添加除臭剂进行除臭；将除臭处理过后的污泥与添加剂混合搅拌，再将混合物送入陈化池陈化；制胚，调色，烘干后进行烧制。本发明先利用臭氧对污泥进行氧化，去除污泥中的有机物，再利用吸附剂吸附污泥中的磷，采用两级干化，充分利用余热，减少资源浪费和能源消耗，并在污泥干燥后，对污泥进行进一步的发酵和除臭处理，在节约能源的同时有效提高污泥胚料的品质，从而使得制得的工艺转经久耐用。
