Description

technical field [0001] The invention relates to a sludge dewatering device, in particular to a roll type submerged membrane capillary deep sludge dewatering device. Background technique [0002] Usually, after dehydration, the water content of the sludge generally reaches about 75%, but the sludge needs to be further processed into organic fertilizers, fuels, etc., and the sludge must be further dehydrated, generally about 20%. The traditional process must go through methods such as deep pressurization and drying. The sludge treatment takes a long time, consumes a lot of steam, power, and electric power, and the cost of sludge treatment per ton is 70-80 yuan. [0003] Sewage treatment will produce sludge, and most of the sludge is activated sludge with a particularly high water content, most of which are organic matter, and also contain toxic substances, heavy metals, phosphorus, ammonia, nitrogen and other substances. If the sludge is not dehydrated, it will be It brings t...

AI Technical Summary

Problems solved by technology

[0003] Sewage treatment will produce sludge, and most of the sludge is activated sludge with a particularly high water content, most of which are organic matter, and also contain toxic substances, heavy metals, phosphorus, ammonia, nitrogen and other substances. If the sludge is not dehydrated, it will be It brings troubles to the comprehensive treatment and utilization of sludge transportation, packaging, deep processing, power generation, incineration, etc. Conventional sludge treatment needs to obtain relatively dry sludge (50% moisture), which must be buried, press-filtered, and centrifugally separated , Vacuum extrusion separation, heating separation and other methods need to consume a lot of power energy, heat energy, time, etc. At the same time, all sludge dewatering equipment is bulky, occupies a large area, is expensive, requires high mechanical maintenance costs, and requires a lot of labor. operate

Calculated according to the moisture content of 80%, my country will produce 30 million tons of sludge by 2010. If the above traditional methods are used to deal with it, it will waste huge funds and energy
