摘要
结合翻译大学污水处理工程案例,分析了学校污水的特点,即在水质方面存在含油量较多,在水量方面存在早、中、晚排水高峰期,学期内水量多,假期期间污水量极少,水量变化系数大,针对上述特点,通过比较现有的成熟技术,指出在污水处理设计时选择采用隔油措施、调节措施、序批式生物反应工艺等技术能够更好地应对上述对污水处理不利的特点。污水的二级处理核心工艺采用序批式活性污泥法不仅能使出水水质达到排放标准,而且极大地解决了学校污水水量变化大的问题。翻译大学污水处理站的实际工艺设计案例进一步证明了工艺选择的正确性和良好的实际出水效果,同时该污水处理工程具有高效、节能等特点,产生了良好的环境、经济效益。
The paper combined with the wastewater treatment case of The college of translation,analysed the characteristic of college wastewater.It has a grate quantity of oil and the quantity of discharge has a big inhomogeneous in a day.And the quantity of discharge is much more when the students in school than on the vacation,fluctuation of the wastewater quantity is large.Aiming at the above characteristics,by comparing the existing wastewater treatment technologies,the paper pointed out that oil separation measures,regulating measures,sequencing batch reactor technology and other technologies can better cope with the unfavorable characteristics of sewage treatment.The usage of sequencing batch reactor can remove the biological nutrient to the required standard and the most important ting is solved the problem that the amount of sewage in the school changes greatly.The case is further proved that the process selection is correct and the actual effluent effect is good.At the same time,the sewage treatment project has the characteristics of high efficiency,energy saving etc.,and has produced good environmental and economic benefits.
