Abstract:
In order to control the problem of water turbidity caused by unstable sediment, the academic thought of using bionic method to realize the stability of sediment was put forward based on studying the formation mechanism of earthworm soil. A polymer ameliorator based on polysaccharide was developed to improve the aggregate structure of sediment, and the encapsulation and solidification mechanism of the aggregate structure was analyzed. The effectiveness of the bionic improved method to inhibit turbidity was verified by the experiment of granulation and SS controlling in the laboratory. The pilot-scale experiment formed the sludge improvement process and related parameters in the engineering scale. The engineering practice further verifies the effective role of the encapsulation and solidification mechanism of the improved aggregate structure on the stabilization of sediment and achieves the expected engineering effect.
