Problems solved by technology

[0003] At present, the industrial automatic production of sludge (moisture content below 85% by weight) is dehydrated into sludge dry powder (water content below 5% by weight), and can achieve no secondary pollution in the production process, occupy a small area, and do not need to be heated. No need to add chemicals, less investment, low cost, fully realize harmlessness, reduction, stabilization, resource utilization, no reports have been seen so far

Abstract

The invention relates to an industrial automatic production method of sludge dry powder by sludge dewatering and equipment thereof. The method realizes industrial automatic production in industrial automatic production equipment of sludge dry powder by sludge dewatering, particularly sludge dewatering machine as main equipment. The sludge of water content below 85 wt% is dewatered to obtain sludge of water content below 5 wt%. The inventive method and equipment realize harmlessness, stabilization and reclamation of sludge dewatering; and can be widely used for dewatering domestic sludge or sediments, industrial sludge or sediments, lake and river course sludge or sediments.

Description

technical field [0001] The invention relates to the field of environmental protection engineering, in particular to an industrial automatic production method and equipment for dehydrating sludge (water content below 85% by weight) into sludge dry powder (water content below 5% by weight). Background technique [0002] At present, domestic and foreign industrial and domestic sewage sludge or (activated) sludge after sewage treatment mainly adopt natural drying, mechanical dehydration, rotary kiln, multi-layer furnace, fluidized bed incineration, aerobic digestion, anaerobic digestion, etc. There are many problems in the treatment method, such as low treatment rate and imperfect process; single technology and outdated equipment; low disposal guarantee rate and high risk of secondary pollution; large investment and low benefit, and some still rely on subsidies; Sludge has no way out, and all resources cannot be used rationally. Some sludge treatment units and even the whole pl...
