Anhui Fengyuan pharmaceutical Limited by Share Ltd odor treatment
Fengyuan pharmaceutical was founded in the last century in 60s, 1997, by the BBCA Group joint five place large pharmaceutical enterprises initiated the establishment of Fengyuan pharmaceutical. Today, Fengyuan pharmaceutical has developed into a large capacity for injection, antipyretic and analgesic, cardiovascular, and women's and children's pharmaceutical raw materials and other products for supporting in pharmaceutical research and development, production and marketing in one of the large pharmaceutical companies, from now on, Fengyuan pharmaceutical entered a period of rapid development, gradually entered the mainstream China ranks: national pharmaceutical enterprises the national high-tech enterprises, "assured the people medicine brand", continuously since 2007 to enter the Chinese pharmaceutical industry 100.
The limited medical sewage treatment station during the operation process of different degree of odor gas, will not only affect the health of employees and work environment of sewage treatment plant, will bring serious harm to the surrounding environment of investment and the daily life of residents. In order to improve the life and create a good investment environment, the feasibility, Anhui Fengyuan pharmaceutical Limited by Share Ltd integrated waste management program effectiveness, economic and other considerations. Combined with the comprehensive review of the local environmental protection departments, the project was decided by the Jiangsu Longtai environmental protection equipment manufacturing Co., ltd.!
General situation of waste gas treatment engineering and exhaust gas index
The sewage station malodorous gas from high concentration regulating pond, comprehensive regulating pond, pool, anaerobic tank, sludge tank, sludge dewatering and sludge storage, mainly containing organic acid, H2S, ammonia, VOC, methane etc..
Air handling capacity: 3600m3/h
The intake of organic / inorganic substances: total concentration of less than 500mg/m3
The intake of odor concentration: less than 15000 (dimensionless)
After the treatment of organic / inorganic substances: total concentration of less than 50mg/m3
The odor concentration after treatment: less than 2000 (dimensionless)
The applicable range and advantages and disadvantages of several waste gas treatment processes
Purification process / process characteristics, safety, purification efficiency, total investment
(one-time investment + operating costs) energy consumption, there are two pollution?
UV lights are unsafe and generally high
Water (chemical) spray + activity
Carbon adsorption (caustic soda),
Hydrogen peroxide, etc.) safe in general
(likely to fail) low high solid waste treatment
Combustion method is unsafe, high, very high
Low temperature plasma is unsafe
(organic waste gases flammable and explosive) high, high, none
LTAOP high safety (95% +) moderate
(operating cost is 1/10 of activated carbon) low none
Biological filter safety is generally high
LTAOP technology principle
The ozone generator generates a positive charge with positive charge of ozone molecules O3+, positive charge, ozone formation of a large number of hydroxyl groups on special oxidation accelerator LTC-A/B developed by our company under the action of (OH), hydroxyl (OH) has a strong oxidation ability. In advanced oxidation decomposition, O3+, involved in the direct reaction of OH in indirect reaction in PH. 4 under the condition of 90% completed by indirect reaction. Especially for the decomposition of odorous gases, the decomposition rate is over 95% after direct and indirect reactions.
Technological process
Waste gas treatment process
Long Tai environmental protection company is currently well documented in the domestic organic waste gas treatment project, the best environmental protection manufacturers.
According to the complexity and diversity of the waste gas treatment project, the long environmental protection company has constantly sum up experience in the practice, constantly technological innovation, and adopt unique design for different projects.
After the comprehensive analysis of the construction cost, operating cost, maintenance cost and purification effect, we suggest that the exhaust gas should be treated with advanced oxidation system.
The exhaust gas through the pipeline into the collection after Longtai LTAOP advanced oxidation system, active free radical oxidation system can produce a large number of hydroxyl radicals and ion agent active groups DMF, piperidine, dichloromethane, three fluorine acetic acid, ethylene two mercaptan, ether, acetonitrile and other harmful pollutants and the chemical reaction, is a large amount of harmful pollutants decomposed into carbon dioxide, water, harmless acid after the catalytic oxidation system, to further processing, hydroxyl radical and ion agent reactive groups in catalytic oxidation agent and residual harmful pollutants react again harmful pollutants to be completely decomposed into carbon dioxide, water and acid alkali absorption system into harmless, thephysico chemical spray the physical and chemical washing spray washing system, the absorption liquid by countercurrent type (neutralization liquid NaOH) atomization spray washing, So as to achieve the clean effect, the scheme not only has high efficiency, but also can efficiently remove DMF, piperidine, methylene chloride, three acetic acid, ethyl two mercaptan, ethyl ether, acetonitrile and other pollutants.
The use of LTAOP waste gas treatment system, the effect can not only meet the national level two emission standards, but also far below the standard, and the operation and maintenance costs are low.

Engineering construction situation
Long Tai environmental protection for odor exhaust treatment, the main process using LTAOP advanced oxidation technology deodorant. After 30 days of equipment production and equipment installation, the nitrogen and oxygen compound waste gas treatment facilities are installed and installed. After a week of debugging, the equipment runs stably and the treatment effect is good. Exhaust gas treatment project by Anhui Environmental Protection Bureau Hefei Baohe acceptance monitoring.
