Novel sludge brick making technique
The invention discloses a novel sludge brick making technique which comprises the following steps that municipal sludge is subjected to dewatering conditioning and desodoration treatment; heavy metal is controlled; treated sludge pug, clay and an additive are blended to form a material; the material is fed into a brute force extrusion mixer to be mixed fully, and is ground and homogenized by brute force roll grinding and aged; the aged brick making pug is fed into an adobe making workshop to be subjected to compression moulding for adobe making; the moulded adobes are fed into a drying room to be dried; and the dried adobes are placed in a back stage of a tunnel kiln to be sintered. According to the technique, the sludge from a sewage plant is mixed with the raw clay directly, so that energy resources consumed due to sludge drying are saved; targeted improvement measures are put forwards to solve the problems of sludge dewatering, odor control, heavy metal stabilization, etc.; the quality performance and the strength grade of sludge bricks are improved by methods of optimizing a sludge blending ratio and feeding the additive, etc.; the reduction, harmlessness, reclamation and industrialization treatment goals on the municipal sludge are realized; and the sludge bricks, serving as a product, have objective economic benefits.
