| titleOfInvention | Method for improving saline-alkali soil by biological two-stage harmless treatment of domestic sludge |
| abstract | The invention discloses a biological two-stage harmless treatment method of domestic sludge, which comprises the steps of firstly digesting the domestic sludge by earthworms in an odorless front stage to obtain a mixture of excess sludge and earthworm cast; inoculating EM bacteria compost, surplus sludge and wormcast mixture, and fermenting to obtain harmless products. The invention also discloses a method for improving the saline-alkali soil by the biological two-stage harmless treatment of the domestic sludge, which effectively solves the problems that the saline-alkali soil is improved by the harmless treatment of the domestic sludge: screening domestic sludge meeting heavy metal limit standards specified in agricultural sludge pollutant control standards (GB4284-2018) to ensure the safety of the heavy metal environment for sludge agriculture; the earthworm and the EM are treated in a two-stage mode, the high-efficiency action time of the earthworm and the EM is staggered, and the advantages of the earthworm and the EM are played; ensures that the domestic sludge harmless products can meet all standards specified in agricultural sludge pollutant control Standard (GB4284-2018), thereby realizing the resource utilization of the domestic sludge harmless products and improving the saline-alkali soil. |
