Title:
POROUS BIOLOGICAL POLYMERIZER FOR RIVER AND LAKE ECOLOGICAL DREDGING AND DEWATERING OF SEDIMENT
Document Type and Number:
WIPO Patent Application WO/2021/114997
Kind Code:
A1
Abstract:
Disclosed is a porous biological polymerizer for river and lake ecological dredging and the dewatering of sediment, which polymerizer is used to treat river and lake sediment which has been polluted by inorganic salts. The porous biological polymerizer is made is made by uniformly mixing 50-70 wt% of agent A and 30-50 wt% of agent B to form irregular spheres of 1-3 mm and crushing the mixture to obtain solid particles with a particle size of ≤ 20 mesh, the pH value thereof being 5.0-6.0, wherein agent A is formed by uniformly mixing 10-30 wt% of cellulose, 20-50 wt% starch, and 20-40 wt% of amino acids; and agent B is formed by uniformly mixing 40-70 wt% of glucoamylase and 30-60 wt% of citric acid. When the polymerizer is used to treat river and lake sediment which has been polluted by inorganic salts, the mud-water separation speed is fast, the quality of the remaining water reaches the surface water five-level standard and higher, and the sediment meets the standards of green planting soil.
