Utilizing the active carbon of bamboo and bone black as filtrating material to compare adsorbability of them, separately confer the removal efficiency of organic matter with different electric current, and add TiO2 with dissimilar weight to the photolysis to observe its removal efficiency of organic matter. In the end, get the best treatment to combine with filtration to form a complete treatment system. The result exhibit that COD removal efficiency separately up to 51.7% and 64.87% of wastewater after filtrate by carbon of bamboo and bone black, after electrolyze with 0.5~3.0A current, the removal efficiency of organic matter separately up to 18.97%, 21.55%, 29.31%, 45.69%, 50% and 56.03%, and after add 0g, 0.1g, 0.2g and 0.3g catalyst into wastewater its COD removal efficiency separately reach 17.24%, 20.69%, 35.34% and 43.97%. According to the result, the study select electrolysis to combine with filtration to form a new treatment system, after disposing with this new treatment system, the removal efficiency arrive at 97.32% and 98.45%, not only transform the intrinsic quality of wastewater but also enhance the removal efficiency. However the concentration of the aluminum ion is 44.7 mg/L, it does not arrive concentration of recycling and reusing.
