工藝流程簡介 

生活污水首先流至粗、細格柵去除粗大懸浮物及漂浮物后流入集水池，集水池出水經泵（考慮來水埋深可能較深，故設置提升泵）提升至調節池，在池內進行均質、均量的調節，出水經提升泵提升至生化系統（缺氧池+接觸氧化池），在缺氧內進行反硝化，通過反硝化細菌將污水中的硝態氮（包括接觸氧化池混合液回流中的硝態氮）轉化為氮氣，在接觸氧化池內通入空氣，以滿足好氧菌對氧氣的需求，同時通過空氣攪拌使池內污泥與污水充分混合，增加污水與好氧菌接觸機率，促進水中污染物的降解，較快去除水中污染物質；好氧池內的出水自流進入二沉池，進行泥水分離；二沉池上清液經消毒后達標排放。 

二沉池的污泥排至污泥濃縮池，經濃縮后送至帶式壓濾機脫水；脫水污泥外運處置，污泥濃縮池上清液和帶機壓濾液回流至集水池。

水處理是指為使水質達到一定使用標準而采取的物理、化學措施。飲用水的最低標準由環保部門制定。工業用水有自己的要求。水的溫度、顏色、透明度、氣味、味道等物理特性是判斷水質好壞的基本標準。水的化學特性，如其酸堿度、所溶解的固體物濃度和氧氣含量等，也是判斷水質的重要標準。

水處理目的是提高水質，使之達到某種水質標準。按處理方法的不同，有物理水處理、化學水處理、生物水處理等多種。按處理對象或目的的不同，有給水處理和廢水處理兩大類。給水處理包括生活飲用水處理和工業用水處理兩類; 廢水處理又有生活污水處理和工業廢水處理之分。其中，與熱工技術關系特別密切的有從屬于工業用水處理范疇的鍋爐給水處理、補給水處理、汽輪機主凝結水處理以及循環水處理等。水處理對發展工業生產、提高產品質量，保護人類環境、維護生態平衡具有重要的意義。

Brief introduction of process flow

Into the pool of sewage flow to the first coarse and fine grid to remove coarse suspended solids and floats, sump water through the pump (water depth may be considered deeply, so set the lift pump) to the regulating pond, homogenized in the pool, adjusting both the amount of water, the lift pump to biochemical system (anoxic + contact oxidation pond), denitrification in the anoxic denitrifying bacteria in the sewage of nitrate nitrogen (including nitrate mixture flow in the contact oxidation tank) into nitrogen, air enters in the contact oxidation pool, to meet the demand of aerobic bacteria of oxygen. At the same time through the air stirred tank sludge and sewage mixed fully, increased contact with sewage aerobic bacteria to promote the degradation of pollutants in water by probability, the rapid removal of pollutants in water; the water flowing in the aerobic tank into the two into the settling tank. The mud water was separated and the supernatant of the two sink was discharged after disinfection.

Two sedimentation tank sludge discharged into the sludge thickening tank, concentrated and sent to the belt filter press dewatering; sludge dewatering Sinotrans disposal, sludge concentration in supernatant and filtrate returned to the sump pressure machine.

Water treatment refers to the physical and chemical measures taken to make water quality to a certain standard of use. The minimum standard for drinking water is formulated by the environmental protection department.  Industrial water has its own requirements. Water temperature, color, transparency, smell, taste and other physical characteristics are the basic criteria to judge the quality of water. The chemical properties of water, such as its acidity and alkalinity, the dissolved solid concentration and the oxygen content, are also an important criterion for judging the water quality.

The purpose of water treatment is to improve the water quality to meet some water quality standards. According to the different treatment methods, there are many kinds of physical water treatment, chemical water treatment, biological water treatment and so on. There are two categories of water treatment and wastewater treatment according to the different object or purpose. Water treatment includes two types of drinking water treatment and industrial water treatment, and wastewater treatment is also divided into domestic sewage treatment and industrial wastewater treatment. Among them, there are very close relations with thermal technology, such as boiler feed water treatment, replenishment water treatment, turbine main condensate treatment and circulating water treatment, which belong to industrial water treatment.  Water treatment is of great significance to the development of industrial production, the improvement of product quality, the protection of the human environment and the maintenance of ecological balance.
