The present invention relates to a microorganism mixture comprising one or more microorganisms selected from the Bacillus, Paenibacillus, lactobacillus, Pseudomonas, Trichoderma, aspergillus, and Saccharomyces genera, and which is useful in treating of solid organic waste. The present invention also relates to a composition comprising said microorganism mixture, a process for preparing said composition, a method for treating solid organic waste, and the use of the microorganism mixture or the composition of the invention in treating solid organic waste.

The present application is related to a method for controlling heavy metal scouring pollution in mines by using a humified product, which comprises steps of: (1) carrying out mixed fermentation on sludge and hyperthermophiles to breed polar humified groups, and then carrying out mixed fermentation on the fermented material and a native material of humus precursors to induce massive production of humus until the humus content reaches a required standard; and (2) mixing and maintaining the humified product of the sludge reaching the standard with mine soil polluted by heavy metals to remedy the polluted mine.

A porous biological polymerizing agent for sediment dewatering in environmental dredging of rivers and lakes is disclosed, which is obtained by thoroughly mixing 50 wt % to 70 wt % of an agent A and 30 wt % to 50 wt % of an agent B into irregular spheres of 1 mm to 3 mm, and crushing the irregular spheres into solid particles with a particle size of ≤20 mesh, and the solid particles have a pH of 5.0 to 6.0. The agent A is obtained by thoroughly mixing 10 wt % to 30 wt % of cellulose, 20 wt % to 50 wt % of starch, and 20 wt % to 40 wt % of amino acid; and the agent B is obtained by thoroughly mixing 40 wt % to 70 wt % of saccharifying enzyme (SE) and 30 wt % to 60 wt % of citric acid.

An apparatus for disposing of organic or sewage sludge waste includes: a storage tank configured to collect and accommodate organic or sewage sludge waste; an agitator which is connected to the storage tank to decompose and dry the organic or sewage sludge waste supplied from the storage tank; a first deodorizer which is connected to one side of the agitator to biologically decompose and remove bad-odour substances from a waste gas generated during an agitating process of the organic or sewage sludge waste; a second deodorizer which heats and removes bad-odour substances contained in the waste gas from which the bad-odour substances have been partially removed by the first deodorizer; and a heat exchanger which heats the waste gas, which flows in the second deodorizer, through heat of the waste gas discharged from the second deodorizer.
