2  处理工艺

本工程废水中属高浓度有机废水，可生化性好，采用生化处理；采用了厌氧UASB和好氧SBR的组合工艺。

废水悬浮物较多的特点，采用格栅和固液分离机两级预处理进行去除，避免对后续UASB的影响。

3 工艺流程

本工程工艺流程

废水先经细格栅去除杂物后，经固液分离机去除麦麸等大颗粒悬浮物，后进入集水井，由潜污泵提升进入调节池，调节水量水质后经过二次提升进入UASB反应器。UASB反应器处理后的出水进入好氧SBR曝气池，处理后达标排放。设计中UASB前设有酸碱调节设施。曝气池产生的剩余污泥重力排入调节池，有调节池提升进入厌氧池。从厌氧UASB池排出的剩余污泥进入污泥浓缩池，经浓缩后由带式污泥脱水机进行脱水处理。浓缩池的上清液和脱水机房清液流回集水井。脱水后的污泥外运填埋或经堆肥等处理后制成生物有机肥。

三技术经济指标

本项目总体投资600万元。运行电耗0.33（Kw·h）/m3废水，直接运行费用为0.35元/m3废水。

在古时候，当时的人类没有先进的水处理技术，为了降低疾病的水传播，他们便是采用简单的格栅截留和自然沉降等方法进行水处理。随后，经过多年观察和总结，他们也是发现了用砂子可以过滤掉细微悬浮物的方法，进而出现了药剂混凝预处理。随着人类文明的不断进步，人类产生的垃圾以及对环境的大肆破坏，导致了水资源受到严重污染。当各种传染病通过水传播，致使不少人染病或者死亡的时候，人们才是发现水处理是何等的重要。也正是如此，人们才逐渐开始研究水处理技术。

从十九世纪末开始，工业技术得到长足发展，工业污水也是逐年翻倍产生。而且当时的工业强国的河流、湖泊也是遭到严重污染，逐渐成为社会公害。人们发现，简单的化学、物理方法以及难以处理这些污水，研究出新型的水处理技术已经急不可耐了。各国的科学家都开始着手研究水处理方法，最早是污水曝气试验，然后又是生物膜法，接着再是人工生物处理法，再到如今具有针对性的离子交换法、电化学法等高新技术。

Inancient times, humans did not have advanced water treatment techniques, andthey were treated with simple grille interception and natural sedimentation inorder to reduce the water spread of the disease. Then, after years ofobservation and summarization, they also found that the sand can be used tofilter out the fine suspension, and then the coagulation pretreatment wasdeveloped. With the continuous progress of human civilization, human waste andthe destruction of the environment have caused serious pollution of waterresources. When all kinds of infectious diseases pass through water and causemany people to get sick or die, it is important to find out what watertreatment is. It is only then that people begin to study water treatmenttechnology.

Sincethe end of the 19th century, industrial technology has come a long way, andindustrial sewage has been doubling every year. Moreover, the rivers and lakesof the industrial powers were severely polluted and gradually became a publicnuisance. The discovery of simple chemistry, physical methods and thedifficulty of dealing with them has led to new water treatment techniques.Scientists of all countries have begun to study water treatment method, is theearliest sewage aeration experiment, then the biological membrane method, thenis the artificial biological treatment method, and then to now targeted ionexchange method, electrochemical processes, such as high and new technology.
