提高污泥溶胞效率是强化污泥厌氧处理的关键.为加强污泥微波预处理溶胞效果,本研究分别考察了常压、半封闭条件下二氧化钛颗粒、碳质材料作为敏化剂与过氧化氢联合进行微波污泥预处理的效果.结果表明,碳质材料敏化剂对微波、过氧化氢-微波污泥预处理产生了负作用,降低了污泥的溶胞效果,而二氧化钛能有效增加污泥中营养物质的释放.当二氧化钛颗粒投加量为0.12 g·g~(-1)干污泥时,SCOD、PO_4~(3-)-P的浓度比单独微波处理分别增加了11.86%、61%;当二氧化钛颗粒投加量为0.24 g·g~(-1)干污泥时,NH_4~+-N释放比单独微波处理高出27.78%.微波辐射作用下投加二氧化钛颗粒产生了羟基自由基,强化了过氧化氢-微波对污泥细胞的氧化作用. To improve the sludge lysis efficiency is the key to strengthen sludge anaerobic treatment.In order to enhance the lysis effect of sludge pretreatment by microwave, the present study examined the effects of atmospheric pressure and semi-closed conditions on the effects of titanium dioxide particles and carbonaceous materials Hydrogen peroxide combined with microwave sludge pretreatment results show that the carbonaceous material sensitizer microwave, hydrogen peroxide - microwave sludge pretreatment had a negative effect, reducing the lysis effect of the sludge, and titanium dioxide Which can effectively increase the release of nutrients in the sludge.When the dosage of TiO2 particles was 0.12 g · g -1, the concentrations of SCOD and PO_4 ~ (3 -) - P increased respectively (11.86%, 61%). When the dosage of titanium dioxide particles was 0.24 g · g -1, the release of NH 4 + -N was 27.78% higher than that of the microwave treatment alone. Under the microwave irradiation, titanium dioxide Hydroxyl radicals are produced by the particles, reinforcing the oxidation of sludge cells by hydrogen peroxide-microwaves.
