Sludge deep dehydration quantitative reduction treatment system

Abstract

The invention discloses a sludge deep dehydration quantitative reduction treatment system. The sludge deep dehydration quantitative reduction treatment system is characterized in comprising a first sludge inlet pump, a wall breaking reactor, a self-suction jet device, a releaser, an ozone generator, a sludge filter press and a circulating pump; sludge is lifted using the first sludge inlet pump toenter the self-suction jet device or the wall breaking reactor; the ozone generator or ozone tail gas is communicated into the wall breaking reactor through the self-suction jet device, the releaseris arranged at the bottom of the self-suction jet device and is arranged at the bottom of the wall breaking reactor, and sludge enters the sludge filter press after being treated by the wall breakingreactor; and the self-suction jet device, the wall breaking reactor and the circulating pump are communicated through pipelines to form a cycle. The self-suction jet device and the releaser are combined for use, so that the ozone utilization rate can be greatly improved, a good sludge treatment effect can be achieved under the condition of low ozone addition amount, and the cost is reduced.

Description

technical field [0001] The invention belongs to the field of sludge treatment, in particular to a sludge deep dehydration reduction treatment system. Background technique [0002] With the development of urbanization and the improvement of sewage collection and treatment rate, the effective treatment and disposal of municipal sludge is becoming more and more urgent. According to analysis, in 2015, my country's sludge (water content 80%) output will reach 40 million tons, and the dry weight of sludge will continue to increase at an annual growth rate of more than 10%. Such a large-scale excess sludge production and such a rapid growth rate pose a great challenge to my country's sludge treatment work. At present, sludge dehydration by filter press is the choice of most of the sewage plants in my country. The design moisture content can be reduced to 80% by adopting traditional medicament conditioning and then into plate and frame filtration. In fact, the moisture content can ...
