In this paper, flocculation and advanced oxidation method were adopted to treat the pressed filtration water of kitchen waste after garbage classification. The concentration of COD, total nitrogen (TN) and total phosphorus (TP) was selected as indexes to evaluate the treatment effect. Optimum conditions for flocculation was 8 g/L PAC and 2 g/L PAM, stirred for 3minutes at a fast speed (300r/min), followed with 15minutes at a slow speed (75r/min), and precipitated for 30minutes. After flocculation, the removal rate of total phosphorus could reach 93 %, and the removal rate of total nitrogen was only 21 %. In the condition of that the initial reaction temperature was 25°C, the dosages of ferrous sulfate and H2O2 were 40g/L and 0.4L/L, respectively, and the reaction time was 40minutes, the COD removal rate reached 87.41~ 99.07% for different pressed filtration waters, but advanced oxidation had no obvious effect on the removal of total nitrogen. This research provided a method for the rapid in-situ treatment of kitchen waste after classification of community domestic waste in the future. [ABSTRACT FROM AUTHOR] |
