Sludge is the product of sewage treatment, which is composed of organic debris, bacteria, inorganic particles and colloids. The main characteristics of sludge are high water content (up to 99%), high organic matter content, easy to rot and stink, and the particles are fine, the specific gravity is small, and it is colloidal liquid. It is a thick substance between liquid and solid, which can be transported by pump, but it is difficult to separate solid from liquid by sedimentation.

Sludge ceramsite equipment It is made of sludge as the main raw material, mixed with appropriate amount of auxiliary materials, through pelletizing and roasting. At present, the application of sludge as an organic additive in ceramsite firing is mainly focused on the use of sludge as an organic additive in ceramsite firing. The amount of sludge used is only about 10%. Therefore, the process conditions and proportioning ratio need to be optimized.

Sludge treatment is a process of sludge reduction, stabilization and harmless treatment. The higher the degree of sewage treatment, the more sludge residue will be produced and need to be treated. Sludge treatment facilities are required in general sewage treatment plants unless land treatment or sewage treatment is used. For modern sewage treatment plants, sludge treatment and disposal has become a complex and expensive part of the sewage treatment system.

 

1. Ceramsite rotary kiln: ceramsite rotary kiln is widely used for the calcination and production of ceramsite with various materials, such as ceramsite sand, clay, yellow mud, river bottom sludge, fly ash, shale, slag, etc. It is also a very important equipment in ceramsite production line. It has the characteristics of high unit volume, long furnace life, high operation rate, stable operation, high heat transfer efficiency and low heat consumption. It is an ideal ceramsite calcination equipment.

 

2. Sludge dryer: the sludge dryer can dry the sludge, which is convenient for the production of sludge bio organic fertilizer. It is a common drying equipment for organic fertilizer manufacturing enterprises. It is possible to treat and incinerate the sludge as a fuel.

 

Sludge is the main raw material for producing ceramsite from sludge, adding appropriate amount of auxiliary materials, through pelletizing and roasting. At present, the application of sludge as an organic additive in ceramsite firing is mainly focused on the use of sludge as an organic additive in ceramsite firing. The amount of sludge used is only about 10%. Therefore, the process conditions and proportioning ratio need to be optimized.
