餐厅污水快速预处理方法研究

Rapid Pretreatment of Restaurant Wastewater

目前大多数营业性餐厅厨房内布置拥挤，可利用空间极为有限，对污水处理装置的外形尺寸要求十分苛刻。事实上，污水在设备内的停留时间若超过２０ｍｉｎ，设备就可能因其尺寸过大而难以被用户接受。为此，提出采用以“离心气浮”复合过程为主要工艺的污水快速处理装置对餐厅污水进行预处理，其理论研究和实际样机的运行结果表明，餐厅污水中悬浮性有机物含量占污水中全部有机物量的较大比例，通过积极地分离其悬浮性有机物质可以大幅度降低污水的有机物浓度。

Abstract The space of most restaurant kitchens is so limited to accept a wastewater pretreatment apparatus with big size In fact the users are reluctant to accept any container with holding time longer than 20 minutes The authors developed a new facility on the basis of centrifuge and air floatation process to pretreat the restaurant wastewater rapidly before it is drained off The theoretical research and the operation of pilot plant are OK Best results have been obtained to remove the suspended organic matters which accounts for the larger portion of total organic pollutants and the output could be better to meet the requirement of discharge standard
