Sludge composting method

The invention provides a sludge composting method, and relates to a sludge treatment method which comprises the steps of preferable accessory selection, CK21 fungus spraying inoculation, heavy metal passivation and powder granulation, and then three-dimensional composite biological organic fertilizer with organic, inorganic and microbial active constituents is obtained. Mushroom compost and pig manure are used as accessories which are easily obtained and degraded, the stacker fermentation time is short, only one time of fermentation is needed, the C/N ratio can be effectively adjusted, and the water content of the sludge is reduced; and the efficient beneficial bio-fungus community CK21 is adopted. The microbial concentration is high, the secretion ability of the enzyme is strong, organic matters can be quickly decomposed so as to prevent the corruption of the organic matters, no odor exists, sludge is used for CK21 inoculation, fermentation starts fast, and the effect is good; and the product is inoculated with the CK21 fungus secondarily so as to further balance and activate nutrients, and the microbial natural reproduction is utilized to realize the is called flower dipping absorbing of the plants to nutrients. The invention has the advantages of optimizing the composting conditions, shortening the composting time, reducing energy consumption of turning, and reducing the damage of the heavy metal on the ecological environment.

Wear-resistant super-hydrophobic super-lipophilic polyurethane sponge and preparation method and application thereof in oil-water continuous separation

The present invention belongs to the technical field of functional materials, and in particular relates to a preparation method of a wear-resistant super-hydrophobic super-lipophilic polyurethane sponge, and the method comprises the following steps: 1) hydrophobic nano-silica and polydimethylsiloxane are uniformly dispersed in n-hexane or anhydrous ethanol to obtain a system A; 2) a cleaned polyurethane sponge is put into the system A obtained in the step 1) for soaking for 1-2h, then taken out, and put into a drying oven for drying to obtain the wear-resistant super-hydrophobic super-lipophilic polyurethane sponge. The preparation method is simple, through nano-silica / polydimethylsiloxane modifying, the surface energy of the polyurethane sponge can be reduced, the surface and bulk phase of the polyurethane sponge both can reach super-hydrophobic super-lipophilic functions. Surface contact angles of organic solvents such as paraffin oil, petrol, diesel oil, n-hexane, acetone and the like on the surface of the polyurethane sponge is 0 degree, and a surface contact angle of water on the polyurethane sponge is greater than 150 degree. The prepared polyurethane sponge has excellent wear resistance, is non-fluorinated and environmentally friendly, and can be used for continuous separation of an oil and water mixture.
