Resourceful treatment method for sludge drying, incineration and granulation
The invention discloses a resourceful treatment method for sludge drying, incineration and granulation, belonging to the technical field of sludge treatment. The method comprises the following steps: crushing dewatered sludge of a sewage plant, sieving the crushed dewatered sludge with a 100-mesh sieve, and taking the crushed construction residue soil as a sludge additive; fully mixing and stirring the sludge and construction residue soil in a stirrer according to a ratio of 1: 1 for 10 minutes; drying the mixture of the mixed sludge and the construction residue soil for 60 minutes at a temperature of 100 DEG C by adopting a drying machine so as to allow the moisture content of the mixture to be reduced to 30%-35%; conducting granulating by using a granulator, wherein a granulation particle size is 8-12 mm; carrying out preheating, wherein a preheating temperature is set to be 300 DEG C, and heat preservation time is set to be 15 minutes; carrying out sintering, wherein a sintering temperature is set to be 1100 DEG C, sintering time is set to be 10 minutes, and after sintering, light aggregate ceramsite with a pore structure inside is formed; and carrying out natural cooling after sintering to obtain a ceramsite product. According to the invention, the use amount of sludge is increased while the mechanical strength of prepared lightweight aggregate is ensured.
一种污泥干化焚烧造粒的资源化处置方法，属于污泥处理技术领域。包括：将污水厂脱水后的污泥破碎后过100目筛，将破碎后建筑渣土作为污泥添加剂；将污泥和建筑渣土按1:1的比例在搅拌机中充分混合搅拌10分钟；采用烘干机对混合后的污泥与建筑渣土混合物进行烘干，在温度100℃下烘干60分钟，使混合物的含水率降低至30％‑35％；使用造粒机进行造粒，造粒粒径为8‑12mm；预热：设定预热温度为300℃，保温时间为15分钟；烧结：设定烧结温度为1100℃，烧结时间为10分钟，经过烧结后，形成内部为孔隙结构的轻集料陶粒；烧结后自然冷却，得到陶粒产品。保证制得的轻集料满足机械强度的同时，提高污泥使用量。
