Para-fat Wastewater Treatment Technology

1, membrane extraction technology
Membrane extraction technology as a new separation technology, is a means of promoting the external energy or chemical potential to selectively permeable membrane for the separation medium, two or more components of a gas or liquid separation, classification, and rich the method of collection, is one of the hotspots usability research. The effects of initial concentration of wastewater, hydraulic conditions, operating temperature, pH value and extract ionic strength of aniline removal efficiency and overall mass transfer coefficient, and the effect of the process Lynchem company’s industrial wastewater treatment. The results showed that the flow rate of 3.05 L / d, a temperature of 50 ℃, DH value of about 1, under the conditions of the membrane tube length 18m, actual industrial wastewater influent concentration of aniline 33081mg / L, the removal rate of aniline will remain at 97 %the above.
Membrane extraction technology with low energy consumption, high efficiency, simple process, small investment and light pollution, etc., it is developing quite rapidly in sewage treatment, food production, energy and pharmaceutical synthesis, chemical production process.
Para 2 grease wastewater treatment, microbial degradation of emerging technologies
Metabolized phenomenon under microbial co-metabolism is the use of microbial degradation of biodegradable organic matter is an important way, now refers to the original can not be easily or metabolic substances provide carbon and energy source (easily degradable organic matter as a growth substrate) in the case of the outside world. Li Jian and other Shanghai University compared the aniline solution as the presence of degradation of aniline under the sole carbon and energy and have co-metabolism substrate.
Aniline under denitrifying condition Biodegradation is denitrifying bacteria under anaerobic conditions for the use of aniline as its own growth and reproduction of carbon, nitrogen and energy to No; as an electron acceptor, aniline degradation to harmless products such as CO: and process H20 and the like. LI Jin-rong etc. Zhengzhou University of dynamic simulation soil column experiments to simulate the infiltration system of Weihe studied under denitrification, environmental behavior of aniline and purification mechanisms in the system.
Microbial treatment of aniline pollutant has the speed, low consumption, high efficiency, low cost, mild reaction conditions, and no secondary pollution, etc., so the use of microbial treatment of aniline technology pollutants has become an important way and research directions .
