The disclosure relates to a treatment method for sludge utilization in a sewage treatment plant, in particular to a method for reducing heavy metal content of sludge-based biocoke. The disclosure includes following steps (1) to (5): step (1): concentrating a residual sludge produced by a municipal sewage treatment plant to be with a moisture content of 95-98%; step (2): conditioning the concentrated sludge in a sludge bioleaching tank for 48 hours, with a pH value of the sludge being reduced to below 4.5; step (3): pumping the conditioned sludge into a high-pressure diaphragm plate and frame for a press filter dewatering to obtain a dewatered cake with a moisture content less than or equal to 50%; step (4): delivering the dewatered cake into a sludge dryer for crushing, heating and drying to obtain the dried sludge with a moisture content of 15-22%; and step (5): carbonizing the dried sludge into sludge-based biocoke at a high temperature in a pyrolytic carbonization device with a carbonization temperature of 500-650° C.

A method for processing raw plant material, especially legumes into protein having a nu-tritional and feed value, bioethanol, biogas and fertiliser materials characterised in that the raw plant material is subjected to a dehusking process, followed by the dehusked raw material being crushed and subjected to extraction with stirring, wherein the insoluble solid fraction is separated and subjected to enzymatic hydrolysis using liquefying and saccharifying enzymes, then subjected to ethanol fermentation, where the produced ethanol is distilled and the digestate is transferred as a substrate for biogas production, and the liquid fraction after the extraction process is subjected to a process of precipitation to a solid form in the form of protein precipitate, which is washed with extraction buffer, after which the liquid residue is removed and subjected to a biogasification process.

A growth medium for fungus is obtained by: (a) treating a mixture of lignocellulosic biomass and water with at least one oxidizing agent and steam at a temperature in a range of from about 130° C. to about 220° C. for a period from about 5 seconds to about 10 hours; (b) periodically measuring a pH of the mixture for substantially an entire duration of the treating step; and (c) as necessary, based on the pH of the mixture measured in step (b), adjusting the pH of the mixture into a range of from about pH 4.5 to about pH 7.5 by adding a base to the mixture. A method for producing the growth medium for fungi and a method for cultivating fungi are also provided.
