本工程工藝流程

廢水先經細格柵去除雜物后，經固液分離機去除麥麩等大顆粒懸浮物，后進入集水井，由潛污泵提升進入調節池，調節水量水質后經過二次提升進入UASB反應器。UASB反應器處理后的出水進入好氧SBR曝氣池，處理后達標排放。設計中UASB前設有酸堿調節設施。曝氣池產生的剩余污泥重力排入調節池，有調節池提升進入厭氧池。從厭氧UASB池排出的剩余污泥進入污泥濃縮池，經濃縮后由帶式污泥脫水機進行脫水處理。濃縮池的上清液和脫水機房清液流回集水井。脫水后的污泥外運填埋或經堆肥等處理后制成生物有機肥。

在古時候，當時的人類沒有先進的水處理技術，為了降低疾病的水傳播，他們便是采用簡單的格柵截留和自然沉降等方法進行水處理。隨后，經過多年觀察和總結，他們也是發現了用砂子可以過濾掉細微懸浮物的方法，進而出現了藥劑混凝預處理。隨著人類文明的不斷進步，人類產生的垃圾以及對環境的大肆破壞，導致了水資源受到嚴重污染。當各種傳染病通過水傳播，致使不少人染病或者死亡的時候，人們才是發現水處理是何等的重要。也正是如此，人們才逐漸開始研究水處理技術。

從十九世紀末開始，工業技術得到長足發展，工業污水也是逐年翻倍產生。而且當時的工業強國的河流、湖泊也是遭到嚴重污染，逐漸成為社會公害。人們發現，簡單的化學、物理方法以及難以處理這些污水，研究出新型的水處理技術已經急不可耐了。各國的科學家都開始著手研究水處理方法，最早是污水曝氣試驗，然后又是生物膜法，接著再是人工生物處理法，再到如今具有針對性的離子交換法、電化學法等高新技術。

After treatment of UASB reactor, the water outlet enters good oxygen SBR aeration tank, and after treatment, it is discharged. In the design, UASB is equipped with acid and alkali adjustment facilities. The residual sludge caused by aeration pool is pumped into the regulating pool, and the adjustment pool is raised to the anaerobic pool. The residual sludge discharged from anaerobic UASB pool enters the sludge thickening pool and is condensed and then dehydrated by the belt sludge dehydrator.

In ancient times, humans did not have advanced water treatment techniques, and they were treated with simple grille interception and natural sedimentation in order to reduce the water spread of the disease. Then, after years of observation and summarization, they also found that the sand can be used to filter out the fine suspension, and then the coagulation pretreatment was developed. With the continuous progress of human civilization, human waste and the destruction of the environment have caused serious pollution of water resources. When all kinds of infectious diseases pass through water and cause many people to get sick or die, it is important to find out what water treatment is. It is only then that people begin to study water treatment technology.

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