Sludge treatment complete equipment

Abstract

Sludge treatment complete equipment comprises a to-be-processed sludge metering and feeding device, a stirring modified device, a metering and feeding device, a heating, sterilizing and deodorizing device, a transit tank, a metering and pumping device I, a dehydrating device I, a liquid bath, a dehydrating device II, a metering and water-feeding device, a drug A metering and administrating device, a drug B metering and administrating device, a drug C metering and administrating device, a metering and pumping device II and a waste gas collecting and treating device. The sludge treatment complete equipment has the advantages that the treatment flow time is short, the environment protection is achieved during treatment, no secondary pollution exists, the energy consumption during treatment is low, the cost is low, and dewatered sludge obtained and heavy metal slag can be comprehensively utilized.

Description

technical field [0001] The invention relates to sludge treatment equipment, in particular to a complete set of treatment equipment for sterilizing, deodorizing, dehydrating, and removing heavy metals from sludge. Background technique [0002] After the sewage entering the sewage treatment plant is treated, it meets the standard and is discharged to the outside, but the sludge is left behind. The sludge not only has a high water content, is easily corrupted, emits a strong odor, but also contains a large number of microorganisms and heavy metals. The high water content, strong odor, large amount of harmful microorganisms and heavy metals constitute the "four evils" of sludge, which cause serious harm to the ecological environment. [0003] With the continuous development of my country's economy, the amount of industrial and urban sewage is also increasing, so the amount of sludge produced is also increasing. At present, the development of my country's urban sludge treatment ...

AI Technical Summary

Problems solved by technology

Among them, the sludge incineration treatment method consumes a lot of energy and emits a large amount of harmful gases such as dioxins, causing secondary pollution to the environment; after the concentration method, the water content is still above 75%, and the energy consumption is high, and the bacterial content is high; drying The water content is still as high as 70-80% after the method treatment, and the energy consumption is high

All these sludge treatment methods are to solve one or two of the aforementioned "four pests". Although they are treated, they continue to cause harm.
