Anaerobic aerobic flocculation precipitation sewage treatment process

厌氧好氧絮凝沉淀污水处理工艺

Abstract

本发明提供一种厌氧好氧絮凝沉淀污水处理工艺,包括以下步骤:污水先经过格栅、集水井后通过水泵进入旋流式沉砂池后流入厌氧膜床进行厌氧生物处理,经厌氧处理后的污水流入曝气生物滤池进行好氧生物处理,好氧处理后进入絮凝反应沉淀后即可排放。本发明以厌氧膜床、曝气生物滤池为主体,以絮凝沉淀为辅,启动快,运行稳定,水力停留时间短,效率高,工艺流程简单,操作实施方便;设备结构紧凑,占地面积小,可比基建投资少,运行费用低,在运行过程中噪音小,无异味,对周围环境无影响,可适用于城市生活污水、酒楼食府、生活小区、部队营房和工厂医院等污水的处理,应用前景较广。
The invented sewage treatment process includes the following steps: making the sewage pass through grill and collecting well firstly, then feeding it into cyclonic settling pin by means of water pump, and making it flow into anaerobic membrane bed to make annaerobic biological treatment, then making the anaerobic-treated sewage flow into aerated biological filter pool to make aerobic biological treatment, then feeding the sewage into flocculation precipitation reaction tank, and discharging it. Said invention uses anaerobic membrane bed and aerated biological fitler pool as main body, uses flocculation precpitation as auxiliary measure, its efficiency is high and technological process is simple, and its application range is extensive.
