针对餐饮废水含油量高，成分复杂等特点，采用格栅-沉淀—吸附工艺处理，经特质无纺布和改性纤维球过滤后（简称前处理）的餐饮废水，再利用核桃壳颗粒吸附，实验结果表明：不需要改变pH值前提下，投加核桃壳颗粒30g/L，吸附20min，振荡强度为120r/min，30℃时，对COD和含油量的去除率均达到 69%以上。

According to characteristics of restaurant wastewater high oil content, complicated composition and others，the grid-precipitation adsorption process was adopted. The characteristics and the modification non-woven filter the fiber ball (hereinafter referred to as the pretreatment) of food waste water and then the walnut grain adsorption. The results indicate：under the conditions of not changing the pH value，dosing quantity of 30 g/L，adsorption time of 20 min and Oscillation strength for 120 r/min，30℃，the removal rates of COD and oil from the actual restaurant wastewater all reach above 69%,showing significant removal efficiency.
