Air purification refers to a certain space, the air particles, harmful air, bacteria and other pollutants are removed, and the indoor temperature, cleanliness, pressure, air velocity and air distribution, noise and vibration and lighting, static electricity control in a certain demand range of engineering.

凈化工程本身是屬于行業(yè)的，它本身又分為市政基礎(chǔ)設(shè)施建設(shè)及工廠裝修建設(shè)以及醫(yī)院環(huán)境衛(wèi)生建設(shè)。屬于空氣方面的環(huán)境工程。我公司司的凈化工程一般是建設(shè)潔凈室的工程。噪聲、有害氣體、粉塵、污水的綜合處理工程。從裝飾的角度來看，凈化工程也屬于裝飾工程，裝飾工程主要分為門窗工程；吊頂工程；隔墻工程；抹灰工程；飾面板（磚）工程；樓地面工程；涂料工程；刷漿工程；裱糊工程。

Purification project itself belongs to the environmental protection industry, which is divided into municipal infrastructure construction, factory decoration construction and hospital environmental sanitation construction. It belongs to the environmental engineering of air. Our company's purification project is generally the construction of clean room project. Comprehensive treatment project of noise, harmful gas, dust and sewage. From the perspective of decoration, purification engineering also belongs to decoration engineering, which is mainly divided into door and window engineering; Ceiling works; Partition wall works; Plastering works; Decoration panel (brick) engineering; Floor engineering; Coating engineering; Brushing engineering; Paperwork.
                                      

工程是將自然科學(xué)原理應(yīng)用到工農(nóng)業(yè)生產(chǎn)部門中去而形成各學(xué)科的總稱。

Engineering is the application of natural science principles to industrial and agricultural production departments to form the general name of various disciplines.

工程是科學(xué)和數(shù)學(xué)的某種應(yīng)用，通過這一應(yīng)用，使自然界的物質(zhì)和能源的特性能夠通過各種結(jié)構(gòu)、機器、產(chǎn)品、系統(tǒng)和過程，是以短時間和精而少的人力做出迅速、可靠且對人類有用的東西。于是工程的概念就產(chǎn)生了，并且它逐漸發(fā)展為一門獨立的學(xué)科和技藝。

Engineering is a kind of application of science and mathematics. Through this application, the characteristics of material and energy in nature can be made through various structures, machines, products, systems and processes. It is a rapid, reliable and useful thing for human beings with short time and less manpower. So the concept of Engineering came into being, and it gradually developed into an independent discipline and technology.
