工藝流程簡介 

生活污水首先流至粗、細(xì)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(jīng)泵（考慮來水埋深可能較深，故設(shè)置提升泵）提升至調(diào)節(jié)池，在池內(nèi)進(jìn)行均質(zhì)、均量的調(diào)節(jié)，出水經(jīng)提升泵提升至生化系統(tǒng)（缺氧池+接觸氧化池），在缺氧內(nèi)進(jìn)行反硝化，通過反硝化細(xì)菌將污水中的硝態(tài)氮（包括接觸氧化池混合液回流中的硝態(tài)氮）轉(zhuǎn)化為氮氣，在接觸氧化池內(nèi)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(nèi)污泥與污水充分混合，增加污水與好氧菌接觸機(jī)率，促進(jìn)水中污染物的降解，較快去除水中污染物質(zhì)；好氧池內(nèi)的出水自流進(jìn)入二沉池，進(jìn)行泥水分離；二沉池上清液經(jīng)消毒后達(dá)標(biāo)排放。 

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

水處理是指為使水質(zhì)達(dá)到一定使用標(biāo)準(zhǔn)而采取的物理、化學(xué)措施。飲用水的最低標(biāo)準(zhǔn)由環(huán)保部門制定。工業(yè)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(zhì)好壞的基本標(biāo)準(zhǔn)。水的化學(xué)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(zhì)的重要標(biāo)準(zhǔn)。

水處理目的是提高水質(zhì)，使之達(dá)到某種水質(zhì)標(biāo)準(zhǔn)。按處理方法的不同，有物理水處理、化學(xué)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(yè)用水處理兩類; 廢水處理又有生活污水處理和工業(yè)廢水處理之分。其中，與熱工技術(shù)關(guān)系特別密切的有從屬于工業(yè)用水處理范疇的鍋爐給水處理、補(bǔ)給水處理、汽輪機(jī)主凝結(jié)水處理以及循環(huán)水處理等。水處理對發(fā)展工業(yè)生產(chǎn)、提高產(chǎn)品質(zhì)量，保護(hù)人類環(huán)境、維護(hù)生態(tài)平衡具有重要的意義。

濟(jì)寧天通機(jī)械有限公司是從事水處理設(shè)備的生產(chǎn)與銷售一體化的公司。公司內(nèi)設(shè)行政部、總工辦、質(zhì)量安全管理部、工程技術(shù)部、經(jīng)營部、財務(wù)部等多個專業(yè)部門，擁有各類管理人員，技術(shù)精湛的員工，專業(yè)的銷售人員。公司自成立以來，至今本著一切為用戶服務(wù)的宗旨，嚴(yán)格做到守合同、重信用，把企業(yè)效益與社會效益集為一體的理念，并使之逐年提高，制定和完善了一系列規(guī)章制度，有力的保證了公司的發(fā)展。

我公司主要產(chǎn)品：水處理設(shè)備，污水處理設(shè)備、廢水處理設(shè)備、工業(yè)污水設(shè)備、農(nóng)業(yè)廢水設(shè)備、雨水凈水設(shè)備、醫(yī)院污水設(shè)備、鋼廠廢水設(shè)備、屠宰場廢水設(shè)備、食品廠廢水處理設(shè)備等多種設(shè)備，可根據(jù)要求專業(yè)定制水處理設(shè)備。

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.
