Problems solved by technology

However, the sludge from rivers and lakes, the sludge from sewage treatment plants, and various toxic and harmful solid wastes from factories and mines produced during governance have caused secondary pollution due to improper disposal, seriously threatening the ecological environment.
At present, the landfill method is generally used to deal with such toxic and harmful substances. However, due to the large amount of such waste, the consequence is that it takes up a lot of land and wastes resources, and the treatment cost is also high; Quantify landfill purpose
It can be seen that there is no ideal method except for final landfill disposal, which is really a "worldwide problem".

Embodiment 1

[0041] Wuxi pure 100% Taihu Lake silt, controlled water drying, so that the water content is dried to about 10%; prepare 2 mold volumes of sludge material (the mold is calculated as 15cm×15cm×15cm), here use 0.1ml of biological solidification Protease stock solution (produced by American Aizyson Joate New Technology Co., Ltd., the same below) + 50 milliliters of water is made into a dilution of biological immobilized protease (1:500); then this dilution is stirred into the above-mentioned In the silt, and evenly stir it into "enzyme silt mixture" (hereinafter referred to as "enzyme silt mixture"); and adjust this "enzyme silt mixture" to the optimum water content (if it is too wet, cool After drying and drying, if it is too dry, add water (choose according to the actual situation), make the module according to the "mud cake geotechnical characteristics test" method, and the anti-leakage rate of the test is: -8 ; The "unconfined strength" test for 7 days of natural air drying is...

Embodiment 2

[0070] 90% of Wuxi Taihu silt, 10% of industrial sludge treated by the sewage plant, controlled water drying, so that the water content is dried to about 10%, and they are evenly mixed; prepare silt and sludge materials with the size of 2 molds Quantity (the mold is counted by 15cm * 15cm * 15cm), here, 0.1 milliliter of biological solidified protease stock solution+50 milliliters of water is made into the dilution (1:500) of biological solidified protease with biological solidified protease; Stir into the above-mentioned silt and sludge, and evenly stir with it to form "enzyme silt, sewage mixture" (hereinafter referred to as "enzyme silt, sewage mixture"); and this "enzyme silt, sewage mixture" "After adjusting to the optimum water content (cooling, drying or adding water - choose according to the actual situation), the module is made according to the mode of the "mud cake geotechnical characteristics test" method, and the anti-leakage rate of the test is: -8 ; The "unconfin...

Embodiment 3

[0098] 90% of Wuxi Taihu Lake sludge is crushed into 10% of batteries with a particle size of 0.5-2.5cm, controlled water drying, so that the water content is dried to about 10%, and they are evenly mixed; prepare silt and sewage with the size of 2 molds The amount of mud (the mold is temporarily calculated by 15cm × 15cm × 15cm), here use 0.1 milliliter of biological immobilized protease stock solution+50 milliliters of water to make the dilution of biological immobilized protease (1:500); The diluted liquid material is stirred into the above-mentioned silt and sludge, and evenly stirred with it to form "enzyme sludge, battery mixture" (hereinafter referred to as "enzyme sludge, battery mixture"); and this "enzyme sludge, battery mixture" "After adjusting to the optimum water content (cooling, drying or adding water - choose according to the actual situation), the module is made according to the mode of the "mud cake geotechnical characteristics test" method, and the anti-leak...

Abstract

The invention relates to a method for treating silt, sludge and / or poisonous harmful solid wastes by bio-solidified protease, and also relates to usage of obtained object by the treatment method. A method for treating silt, sludge and / or poisonous harmful solid wastes by bio-solidified protease is characterized in that the method comprises steps of 1) controlling-water and drying the silt, the sludge and / or the poisonous harmful solid wastes disintegrated by certain particle size for solidification, 2) preparing the silt, the sludge and / or the poisonous harmful solid wastes for solidification to form soil sample under being processed, 3) diluting stock solution of the bio-solidified protease by water into diluted solution of the bio-solidified protease, then adding to the soil sample to uniformly stir and mix into enzyme-soil mixture with optimum moisture content,4) stowing the enzyme-soil mixture and enclosing. The method resolves the treatment problem of the present silt, sludge and poisonous harmful solid wastes.

Description

technical field [0001] The invention relates to a method for treating sludge, sludge and toxic and hazardous solid wastes allowed to be landfilled with biological immobilized protease, and also relates to the use of the obtained product of the treatment method. Background technique [0002] Human beings are seriously polluting the ecological environment while building material civilization. However, the sludge from rivers and lakes, sludge from sewage treatment plants, and various toxic and harmful solid wastes from factories and mines produced during treatment have caused secondary pollution due to improper disposal, seriously threatening the ecological environment. At present, the landfill method is generally used to dispose of such toxic and harmful substances. However, due to the large amount of such waste, the consequence is that it takes up a lot of land and wastes resources, and the treatment cost is also high; Quantify landfill purposes. It can be seen that there i...
