| titleOfInvention | Treatment process of leather solid waste |
| abstract | The invention discloses a treatment process of leather solid waste, which comprises the following steps: 1) removing calcium by using ammonium chloride, 2) crushing, 3) sequentially performing cellulase enzymolysis, protease enzymolysis and lipase enzymolysis, 4) microalgae pre-planting and 5) microalgae putting. The treatment process effectively utilizes the nutrient substances of the leather curing waste as the carbon source and the nitrogen source for the growth of the microalgae, and utilizes the biological curing and biodegradation effects of the microalgae, thereby effectively reducing the content of hexavalent chromium in the waste. |
