方案详情:
碳基纳米材料是废水处理工艺的理想材料Carbon-Based Nanomaterials as Promising Material for Wastewater Treatment Processes
This process was based on a mixture of raw wastewater and excess sludge supernatant collectedfrom "Jamno" Wastewater Treatment Plant("J"WTP; located within Koszalin city area, Poland).Moreover, we used activated sludge biomass obtained from the biological aeration tank of"J"WTP. Thebatch experiment was performed within conical flask containers (250 mL) placed on the shaker (24h,150 rpm; Laboshake Gerhardt Typ RO 500, Germany) at room temperature. Using this experimentalsetup several mixtures were investigated including:
(1) 100 mL mixture of raw wastewater and sludge supematant (1:1; v/v) combined with givencarbon material at dose 500 mg/L. After reaction time (24 h) the resulting liquid was filtrated usingcellulose filter (diameter 125 mm, medium type, producer Chemland, Poland) and analyzed.
(2) 75 mL mixture of raw wastewater and sludge water (1:1; v/v) combined with 75 mL of activated sludge (concentration 3.8 g/L) sample and given carbon material at dose 500 mg/L. After reaction time (24 h) resulting suspension was spitted into two parts. One volume (70 mL, approximately) was filtrated as above and the second volume (80 mL, approximately) was used for analysis of activated sludge parameters.
