    畢設基本摘要

    摘要
    本設計是蘇北地區某污水處理廠的初步設計,污水通過格柵、平流沉砂池、輻流初沉池、A2/O、輻流二沉池等構筑物的處理使污水中的污染物質得到有效的去除,而污泥在貯泥池經濃縮,脫水,干化處理后達到穩定化、減量化、無害化、綜合利用等目的以達到保護環境的目的。城市污水經處理后,30%作為城市景觀環境用水,用于湖泊水源水,且不能影響周邊環境,從而達到了污水處理廠的經濟、環保的目的。
    依據污水的水質、水量以及受納水體的環境容量等相關資料,必須對其進行二級體會理方可去除水中的有機污染物,達到排放標準進而保護環境,經過方案比較本設計采用A2/O工藝,其工藝在系統中可以稱為最簡單的同步脫N除P工藝,其總的水力停留時間少于其他同類工藝,在厭氧(缺氧),好氧交替運行備件下,無污泥膨脹現象,污泥有很好的肥效等優點,且污泥較穩定,污泥經濃縮脫水后進行泥餅外運減少了環境污染。
    通過此設計,也更加了解污水處理廠處理的污染問題能得到較好的解決而產生良好的環境效益,同時也會收到很好的經濟效益和社會效益。

    Abstract
    This design is the northern area of the initial design of a sewage treatment plant, sewer through grilles, advection grit, spoke at the beginning of the stream sink pool, A2/O, spoke stream secondary structures such as process wastewater pollutants get effective removal, and the sludge to mud pools through concentrated, dehydration, stem-achieve stabilization, harmless, including aim to achieve the objective of protecting the environment. Municipal sewage treatment, 30% of the urban landscape of water, lake water sources, and cannot affect the surrounding environment, so as to achieve a sewage treatment plant for the purpose of the economic and environmental protection.
    According to the sewage water quality, water quantity and water environment capacity and other related materials, you must only be secondary experience regulating removal of organic pollutants, to achieve the emission standards and the protection of the
    This design is the northern area of the initial design of a sewage treatment plant, sewer through grilles, advection grit, spoke at the beginning of the stream sink pool, A2/O, spoke stream secondary structures such as process wastewater pollutants get effective removal, and the sludge to mud pools through concentrated, dehydration, stem-achieve stabilization, harmless, including aim to achieve the objective of protecting the environment. Municipal sewage treatment, 30% of the urban landscape of water, lake water sources, and cannot affect the surrounding environment, and make the most of the water and resolve the problem of the shortage of water resources, so as to achieve a sewage treatment plant for the purpose of the economic and environmental protection.
    According to the sewage water quality, water quantity and water environment capacity and other related materials, you must only be secondary experience regulating removal of organic pollutants, to achieve the emission standards and the protection of the environment, through plan comparison this design incorporates A2/O technology, their processes in the system can be referred to as the simplest synchronization of N addition P process, its total hydraulic retention time of less than other similar technology, anaerobic (hypoxia), aerobic alternating run under spare parts, no bulking phenomenon, sludge has very good efficiency, etc., and the sludge, sludge through more stable sludge cake after transportation reduces the environmental pollution.
    With this design, you know more about the sewage treatment plant pollution problems can get a better fix and produce good environmental benefits, but also receive good economic and social benefits.
    Keywords  A2/O process; sewage treatment plant; sludge treat
