NOVELTY - Production of bricks from biodegradable sludge comprises biological anaerobic oxidization by placing sludge with high volatile organic substance (20-80%) in fermentation tank, fermenting, drying, filtering and dehydrating; stirring and mixing, grinding dry sludge and shale, and aging; extruding aged brick and shaping to obtain wet brick blank; placing the wet brick blank on kiln trolley, introducing in drying kiln, drying in baking kiln hot air; and transmitting dried brick in channel baking kiln, and baking to obtain sintered product.    USE - Method for producing bricks from biodegradable sludge.    ADVANTAGE - The traditional technique performs the filter dehydration directly and can only reduce the water amount of sludge to about 80%, and the volatile amount of organic substance is greater than 20%. Ordinarily, the sludge with 80% of water amount and greater than 20% organic substance amount can produce 30% bricks by weight of the raw material. Compared with the traditional technique, the method obtains brick producing sludge adaptive to adding brick producing raw material such as shale; the organic substance amount in the sludge is reduced to less than 10%; the water amount is reduced to 20-30%; the sludge produced brick is 40-60% of the total weight of brick producing raw material, thus saving the raw material, reducing the cost and greatly increasing the sludge treatment amount.    DETAILED DESCRIPTION - Production of bricks from biodegradable sludge comprises:    (A) biological anaerobic oxidization by placing sludge with high volatile organic substance (20-80%) in fermentation tank, fermenting at 30-40 degrees C for 7-10 days to obtain fermentation sludge with less than 10% organic substance amount;    (B) drying, filtering and dehydrating the fermentation sludge to obtain dry sludge with 20-30% water;    (C) stirring and mixing, grinding the dry sludge and shale uniformly, aging in an aging tank, where the dry sludge is 40-60% of the total weight;    (D) adding the aged brick in vacuum brick extruder, extruding and shaping to obtain wet brick blank;    (E) placing the wet brick blank on kiln trolley, introducing in drying kiln, drying in baking kiln hot air at 100-150 degrees C for 23-25 hours; and    (F) transmitting the dried brick in channel baking kiln, baking at 1000-1100 degrees C for 24-32 hours to obtain sintered product.
