化工廢氣處理：

    化工廢氣是指化工生產(chǎn)制造中產(chǎn)生的有毒有害的氣體?；U氣中含有的污染物種類很多，物理和化學(xué)性質(zhì)復(fù)雜，毒性也不盡相同，嚴(yán)重影響人體健康和污染環(huán)境。按照污染物存在的形態(tài)，化工廢氣可分為顆粒污染物和氣態(tài)污染物——通常顆粒污染物主要有塵粒、粉塵、煙塵、霧塵、煤塵等；氣態(tài)污染物主要有含硫化合物、含氯化合物、碳氧化合物、碳?xì)浠衔?、鹵氧化合物等。

制藥工業(yè)廢氣處理：

    生物制藥行業(yè)的廢氣，也是值得關(guān)注的主要污染源之一，以其代表性的原料藥車間為例，其生產(chǎn)過程主要四個(gè)步驟，基本為間歇式投料，24小時(shí)生產(chǎn)，在排出的廢氣中含有甲苯、乙酸乙酯、甲醇、二氧六環(huán)、三乙胺、DMSO等多種復(fù)雜的有機(jī)物成分，現(xiàn)部分車間已用PVC管和PVC收集罩收集后輸送到簡(jiǎn)易水洗塔經(jīng)過水洗排放。排放廢氣中有機(jī)物的總濃度平均值約為1500毫克/立方米左右，對(duì)廠區(qū)及周邊環(huán)境造成較大的污染，環(huán)境需要進(jìn)行有效治理，已達(dá)到國(guó)家規(guī)定的排放標(biāo)準(zhǔn)。生物制藥干燥廢氣處理、藥行業(yè)生產(chǎn)過程中在發(fā)酵、干燥、污水處理等工序均產(chǎn)生大量的惡臭異味氣體，發(fā)酵工段產(chǎn)生的含氨廢氣（擴(kuò)散型）未經(jīng)處理、生產(chǎn)過程中產(chǎn)生的廢氣已影響企業(yè)的環(huán)境空氣質(zhì)量和人體健康，亟待處理。

涂裝行業(yè)廢氣處理：

    涂裝是產(chǎn)品表面保護(hù)和裝飾采用的最基本的技術(shù)手段，涂裝作業(yè)遍及國(guó)民經(jīng)濟(jì)各個(gè)部門：家具、汽車等金屬、塑膠、竹木制品加工制作作業(yè)、涂裝車間與打造成型（切、銷、磨）車間是環(huán)境污染主要的生產(chǎn)場(chǎng)所。在噴涂作業(yè)中，溶劑型涂料的50%~70%在涂裝過程中以漆霧飛散掉，涂料中絕大本分有機(jī)溶劑揮發(fā)釋放到空氣中。

污水處理廠惡臭氣味處理：

    各個(gè)行業(yè)污水處理站點(diǎn)與城市污水處理廠在運(yùn)行過程中產(chǎn)生擾民的惡臭氣味，污水處理工程中產(chǎn)生的惡臭成分主要是由蛋白質(zhì)、脂肪、碳水化合物的微生物呼吸、發(fā)酵過程的產(chǎn)物和不產(chǎn)物、一般分為一下三類

1.含硫化合物——硫化氫、硫化鉀、甲基硫醚等；

2.含氮化合物——氨三甲胺；

3.碳、氧或碳、氫、氧組成的化合物——低級(jí)醇、醛、脂肪酸。

惡臭氣味主要產(chǎn)生環(huán)節(jié)在于進(jìn)水格柵、調(diào)節(jié)池、曝氣塵沙池、厭氧池、缺氧池、曝氣池、污泥濃縮池和污泥中轉(zhuǎn)等工序。

垃圾固廢中轉(zhuǎn)站及填料場(chǎng)臭氣處理：

    垃圾中轉(zhuǎn)站的目的是把居民區(qū)垃圾集中后，壓縮打包，在運(yùn)送至垃圾填理場(chǎng)或垃圾處理廠進(jìn)行集中處理。垃圾的生產(chǎn)、收集、運(yùn)輸過程中同時(shí)伴隨著發(fā)酵與腐爛，散發(fā)出以硫化氫、氨氣、甲硫醇、甲硫醚為主的惡臭氣體，且車輛進(jìn)出、裝卸時(shí)引起垃圾滲濾液滲漏和揚(yáng)塵，對(duì)周邊產(chǎn)生滋擾。

Chemical waste gas treatment:

    Chemical Waste Gas refers to chemical manufacturing generated toxic and harmful gases. Chemical pollutants in the exhaust gas species contained a lot of complex physical and chemical properties, toxicity, are not the same, serious impact on human health and pollute the environment. In accordance with the form of the presence of pollutants, chemicals can be divided into the exhaust gas particulate pollutants and gaseous pollutants - usually particulate pollutants are mainly dust particles, dust, smoke, fog and dust, coal dust; gaseous pollutants are mainly sulfur compounds, chlorine compounds, oxides of carbon, hydrocarbons, halogen-oxygen compounds.

Pharmaceutical industrial waste gas treatment:

    One of the main sources of gas in the biopharmaceutical industry, is also noteworthy for its most representative pharmaceutical raw materials workshop, for example, four major steps of its production process, substantially intermittent feeding, 24-hour production, in the exhaust gas contains a variety of complex organic components toluene, ethyl acetate, methanol, dioxane, triethylamine, DMSO, etc., are part of the plant has been using PVC pipe and PVC cover collection after collection transported to simple washing after washing tower emissions. The total concentration of organic matter in the average emissions of about 1500 mg / cubic meter, the plant site and the surrounding environment cause greater pollution, environmental need for effective governance, have reached the national emission standards. Biopharmaceutical drying gas processing, pharmaceutical industry in the production process of fermentation, drying, sewage treatment and other processes are generating a lot of stench smell of gas, ammonia gas generated by the fermentation section (diffusion) of untreated exhaust gas generated in the production process has been affect ambient air quality and human health, urgent treatment.

Paint industry waste gas treatment:

    Painting is the most basic technology products surface protection and decorative uses, painting jobs throughout the various sectors of the national economy: furniture, autos and other metals, plastics, wood products processing and production operations, paint shop and create shape (cut, pin , grinding) plant is the main production sites of environmental pollution. In spraying operations, 50% to 70% solvent-based coatings in the coating process in order to fly out of the mist, paint the vast sub-volatile organic solvents released into the air.

Sewage Treatment Plant bad odor treatment:

    Site sewage treatment industries and urban sewage treatment plant odor nuisance odor during operation, malodorous components sewage treatment project is mainly generated by the breathing of protein, fat, carbohydrates microbial product of the fermentation process and incomplete product, what is generally divided into three categories

1. The sulfur compounds - hydrogen sulfide, potassium sulfide, methyl sulfide and the like;

2. The nitrogen-containing compounds - ammonia trimethylamine;

3. The compound of carbon, oxygen, or carbon, hydrogen and oxygen consisting of - lower alcohols, aldehydes, fatty acids.

The main aspects that produce foul odors inlet grille, regulation pool, dust aeration tank, anaerobic tank, anoxic, aeration tank, sludge thickener and sludge transfer processes.

Refuse solid waste transfer station and a filler field Odor Treatment:

    Refuse transfer stations aim is to focus on residential garbage after compression packaged, transported to the landfill management in the field or waste treatment plant for centralized treatment. Waste production, collection, transport process is accompanied by fermentation and decay, it emits hydrogen sulfide, ammonia, methyl mercaptan, dimethyl sulfide-based malodorous gases and vehicle access, causing leakage of leachate when loading and unloading and dust on the surrounding generate nuisance.
