Problems solved by technology

The three wastes produced in this incineration process still continue to produce secondary pollution. Not only have they not been treated well, but they also need to be supplemented with external fuels. New sources of pollution such as dust and dioxins produced in the incineration process will cause serious damage to the air and the environment. new pollution
At present, there are many factors restricting the construction of sludge treatment and disposal facilities, but the overall technical route of national sludge treatment and disposal is not clear enough is one of the important restricting factors

Embodiment 3

[0057] The design method of a sludge treatment device in Example 3 of the present invention includes the overall design of the machine base, the sludge treatment drum, the power drive mechanism, the output pipeline, the machine cover and the specific design of each component. The design method of the above-mentioned sludge treatment device is to add a certain amount of glucose powder to the modified sludge with a water content of 25-30% according to the difference in heavy metal content in the sludge, and then add a certain amount of glucose powder under normal pressure and different temperatures. Under the same conditions, it passes through three sludge treatment drums in turn, and performs three process steps of heavy metal and dehydration and denitrification treatment, carbonization treatment, and fixed carbon combustion treatment during the process of mechanical stirring and uniform rotation of the drums; the treated sludge meets the national standards. The standard for agr...

Abstract

The invention discloses a designing method of a sludge processing apparatus and an apparatus thereof, which belong to the technical field of sludge processing. The designing method of the sludge processing apparatus comprises an integral design of an engine base, a sludge processing roller, a power drive mechanism, an output pipeline and an engine cover as well as a concrete design of each component, the designing method is characterized in that according to the different heavy metal contents in the sludge, the modified sludge with water content being 25-30% is placed in three different sludge processing rollers in order, quantitative glucose powder is added for mechanical stirring at uniform speed for propulsion, and three technical steps of heavy metal and dehydration / denitrification treatment, carbonization treatment and fixed carbon combustion treatment are carried out under normal pressure condition at temperature of 100-450 DEG C. Compared with the prior art, the designing method and the sludge processing apparatus have the advantages of novel and reliable performance, and no secondary pollution; waste can be changed into valuables, and sludge harmlessness treatment is realized, and the designing method and the sludge processing apparatus realize protrude substantiality characteristic and obvious progress for resource processing.

Description

technical field [0001] The invention relates to the technical field of chemical industry and environmental protection, in particular to a design method for sludge, especially a sludge treatment device of urban sewage treatment plant and the technical field of the device. Background technique [0002] In recent years, with the rapid improvement of my country's sewage treatment capacity, the amount of sludge has also increased significantly. As of the end of March 2013, as far as sludge from urban sewage treatment plants is concerned, a total of 3,451 urban sewage treatment plants have been built in cities and counties across the country, with a sewage treatment capacity of about 145 million cubic meters per day, and annual production of sewage with a water content of 80%. There are more than 35 million tons of sludge, and there are about 120 sewage treatment plants increasing each year. According to statistics, about 80% of sewage plants have sludge concentration and dehydra...
