Wastewater from Kenaf degumming and modifying treatedwith a Chitin-Biomembrane method
The wastewater composition produced in the kenaf degumming and modifying process is composed of monosaccharides, monosaccharide derivatives, as well as polysaccharides and solids, such as galacturonic acid, methyl ester, galactose, xylose, glucose and arabinose, which analyzed by using gas chromatograph. These saccharides are served as carbon sources and prior to be absorbed by microbes. Moreover, the temperature and pH conditions of the wastewater also favor the microbe growth. Thus a biological chain of carbon source-microbe growth-wastewater treatment can be formed. The chitin is selected as carrier which can easily solidify biomembrane. The wastewater produced in the kenaf degumming and modifying process is treated with the biomembrane treatment device. The optimum processing parameters are determined based on single factor and orthogonal tests, and they are respectively time=l8h, pH=7, initial COD=450, temperature=27°C. The experimental results indicate that all waterquality indexes can reach level-2 criteria of the integrated wastewater discharge standard after this biomembrane treatment.
