Description
Technical Field
The utility model belongs to the technical field of solid waste cyclic utilization, concretely relates to device of papermaking wastewater plant chemical sludge preparation desulfurizer.
Background
In newsprint factories, waste water produced after waste paper deinking is mainly treated by processes such as a sedimentation tank, anaerobic treatment, aerobic treatment, Fenton advanced oxidation treatment and the like. The sludge after the aerobic treatment process is called biological sludge, and can be directly combusted in an incinerator because the fiber content is high and the heat value can reach more than 3000 calories; the sludge after Fenton advanced oxidation treatment is called chemical sludge, most of various organic substances in the sewage are oxidized by the Fenton reagent after the process, the organic matter content in the residual sludge is low, the residual sludge is low in heat value and cannot be combusted, and landfill causes pollution to the environment. Through analysis, the dryness of the chemical sludge is 45-50%, the content of organic matters is 30-40%, and the content of the rest inorganic matters is about 60-70%. The analysis and test of the inorganic substance by a scanning electron microscope-energy spectrometer show that the main elements are three elements of Si, Fe and Al, and the element with the largest content is the Fe element. (the source of Fe element is mainly that FeSO is added in the Fenton advanced oxidation process4The source of Si element is sodium silicate Na added in the process of deinking waste paper2O▪nSiO2The source of Al element is polymerized AlCl added in the process of papermaking3)。
At present, the method for treating chemical sludge in a paper mill comprises the steps of mixing the chemical sludge with precipitated sludge and secondary biological treatment excess sludge, adding an inorganic conditioner and a polymeric flocculant, pumping the mixed sludge to a sludge dewatering machine for dewatering, and burning or burying the dewatered sludge for subsequent treatment. However, the method adds a large amount of inorganic conditioner and polymeric flocculant, which not only increases the chemical dosing cost of sludge treatment, but also increases the quality of sludge dehydration, increases the dehydration load, and simultaneously has low recovery rate of iron element in the sludge, can not realize the concept of recycling waste resources, generates more waste gas which is difficult to treat when being combusted with biological sludge, and is extremely unfavorable for tail gas treatment.
