混凝磁分离法处理厨房污水

Treatment of Kitchen Wastewater by Coagulation and Magnetic Separation

采用混凝磁分离法处理厨房污水，研究了适宜的磁粉和混凝剂搭配量及加料次序的影响，并进行了磁混凝与普通混凝的对比试验。采用自行研制的设备连续处理含油量和悬浮物分别为１４９ｍｇ／Ｌ和２８５ｍｇ／Ｌ的厨房污水，其出水含油量及悬浮物可分别减少到５．２ｍｇ／Ｌ和６８ｍｇ／Ｌ，占地面积则仅为混凝气浮池的一半。

Treatment of kitchen wastewater by coagulation magnetic spearation method is reported in this paper. The dosage and dosing sequence of magnetic powder and coagulant were studied. The comparsion between coagulation magnetic separation and conventional coagulation was also carried out. The concentration of oil and suspended sokids were reduced from 149 mg/L and 285 mg/L in influent to 5.2 mg/L and 68 mg/L in effluent respectively after treatment by the equipment developed. Space occupied by the equipment was only half of that by dissolved air flotation process.
