Problems solved by technology

However, since the sludge incineration process will produce harmful gases, and the effective removal and purification of these gases requires a large amount of facility investment, this technology is facing two challenges: "high operating costs and poor public acceptability"
The existing sludge is easy to produce odor after long-term storage, and cannot effectively deal with the odor during treatment, which is likely to damage the health of the staff

Abstract

The invention discloses an intelligent device for treating sludge. The intelligent device comprises a pretreatment unit for detecting and adjusting the PH value of the sludge, a wet oxidation treatment unit for performing wet oxidation treatment on the sludge, a hydrothermal carbonization treatment unit for performing hydrothermal carbonization treatment on the sludge and a catalysis unit for adding a catalyst to the wet oxidation treatment unit and / or the hydrothermal carbonization treatment unit. The PH value of the sludge is adjusted by the pretreatment unit, then, a wet oxidation reactionis conducted in the wet oxidation treatment unit, volatile suspended solids in the sludge are removed, then, a hydrothermal carbonization reaction is conducted in the hydrothermal carbonization treatment unit, and the sludge is processed into biochar and a liquid phase product, so that harmless and reduction tretament of the sludge and reduction of emission of sludge carbon are realized.

Description

technical field [0001] The invention relates to the technical field of environmental engineering sludge treatment, in particular to an intelligent device for sludge disposal. Background technique [0002] A large amount of sludge will be generated during sewage or wastewater treatment. Taking urban sewage treatment plants as an example, every 10,000 cubic meters of sewage will produce 5 to 10 tons of dewatered sludge (based on a moisture content of 80%). According to the requirements of my country's "Twelfth Five-Year Plan" National Urban Sewage Treatment and Reuse Facilities Construction Plan, by 2015, the scale of urban sewage treatment in my country will reach 208.05 million cubic meters per day. Based on this estimate, only urban sewage treatment plants in my country will 37.97-75.94 million tons of dewatered sludge will be produced every year; in addition to urban sewage treatment plants, papermaking, food processing, petrochemical, printing and dyeing industries all pr...
