[0026] Implementation column 1
[0027] Today there are 100 cubic meters of oily sludge with an oil content of 6%. The first step is to remove solid waste with a volume of more than 10 cubic centimeters such as stones and asphalt blocks in the oily sludge, and spread the oily sludge on a site of about 250 square meters with a thickness of 40 cm. The surface of the site is concrete anti-seepage Repeated rotary tillage with a rotary tiller, and at the same time add 0.3% crude oil decoagulant by sludge weight until it is fully mixed with the soil. Take a typical oily sludge sample at a land temperature of 25°C, and select effective strains with a degradation efficiency of more than 30% through directional screening. After multiplication and adsorption with wheat bran, a solid bacterial agent with a moisture content of 10% is prepared for the next step. Pseudomonas aeruginosa of the genus Pseudomonas, Micrococcus luteus of the genus Micrococcus, Bacillus subtilis of the genus Bac...
