Abstract： |
The present invention relates to the preparation process of controlled releasing high molecular carbon source material for biological water treating process, and belongs to the field of water treating technology. The preparation process includes the steps of consoluting solution, enzymolysis, mechanical mixing and repeated freezing formation. The main material includes natural high molecular material 10-80 wt%, artificially synthetic material 10-70 wt%, deoxidizing agent 0-3 wt%, pH regulator 0-3 wt%, cross-linking agent 0-1 wt%, and compatibilizing agent 0-25 wt%, as well as bioactive enzyme in 0-5 u/g of the natural high molecular material. The prepared carbon source material has high mechanical performance, is suitable for various water treating technological processes including in-situ biological underground water repair. Test shows that the carbon source material can release organic carbon effectively for long time. |
