Embodiment 1

[0038] The present invention proposes a system for improving sludge treatment efficiency. The treatment system includes a pretreatment unit 1, a heat exchange unit 2, an oxidation matrix unit 3, a reactor 4, a separation unit 5, and a catalyst input unit 6. The reactor 4 are respectively connected to the heat exchange unit 2, the oxidation matrix unit 3 and the separation unit 5, and the pretreatment unit 1 is respectively connected to the heat exchange unit 2, the separation unit 5 and the catalyst input unit 6.

[0039] The pretreatment unit 1 includes a sludge storage tank 7 for storing sludge, a preprocessor 8 connected to the sludge storage tank 7 and a catalyst input unit 6, a solid pump for transporting sludge, and a Stirrer in Processor 8.

[0040]In the pretreatment unit 1, the sludge with a water content of 75% to 85% in the sludge storage tank 7 is injected into the preprocessor 8 with a solid pump, and the liquid phase of the separation unit 5 is returned to the pr...

Embodiment 2

[0059] The present invention also provides a method for improving sludge treatment efficiency, said treatment method comprising the steps of:

[0060] A. Inject the sludge stored in the sludge storage tank 7 into the preprocessor 8 with a solid pump, mix it with the liquid phase reflux water of the separation unit 5 in the preprocessor 8, and add the catalyst through the catalyst input unit 6, and prepare into a material with a moisture content of 90%.

[0061] In the sludge storage tank 7, the sludge with a water content of 75% to 85% is mixed with the liquid-phase backflow water to form a material with a water content of 90%. The liquid-phase circulating water is acidic with a pH of 4 to 5. Under the action of acid, the sludge will break down, causing some cells to dissolve and free water to increase. Moreover, due to the high temperature of the return water, the original sludge will be preheated. . Under the synergy of these aspects, the fluidity of the mixed sludge in th...

Abstract

The present invention relates to a sludge treatment efficiency improvement system and method, cell wall of cells in sludge is broken by high temperature and pressure, and cell water in the cells is removed, so that subsequent solid-liquid separation is easier. More importantly, by use of the principle of hydrothermal oxidation, ozone is added in an oxidizing matrix, organic matters in the sludge are thoroughly and quickly oxidized in a liquid phase, and sludge treatment efficiency is greatly improved. On the other hand, a catalyst is added into the sludge to reduce the activation energy of the reaction, so that the desired reaction temperature is reduced, energy consumption is saved, reaction speed is further accelerated, productivity is increased, and production cost is reduced.

Description

technical field [0001] The invention relates to the field of sludge treatment, in particular to a system and method for improving sludge treatment efficiency. Background technique [0002] Since entering the "Eleventh Five-Year Plan", my country's sewage treatment industry has developed rapidly, and the sewage treatment capacity and treatment rate have increased rapidly, which has brought about a rapid increase in sludge production. According to the data of the Ministry of Housing and Urban-Rural Development, by the end of 2009, the national urban sewage treatment volume reached 28 billion cubic meters, and the production of wet sludge (with a moisture content of 80%) exceeded 20 million tons. According to the survey results, 80% of the sludge produced by my country's sewage treatment plants has not been properly treated, and the random accumulation of sludge and the pollution and re-pollution problems caused by it have become prominent and have aroused social concern.
