Abstract:
    The solid normal temperature sodium hydroxide treatment process for raising march gas yield of anaerobically digested wheat stalk includes: 1. the step of chemical pre-treatment through mixing certain concentration of sodium hydroxide solution and crushed wheat stalk and sealing the mixture in some container; and 2. the step of anaerobic digestion to produce marsh gas in an anaerobic digesting apparatus with the mixture and through adding water properly, regulating the carbon/nitrogen ratio of the whole digested system, regulating digesting temperature, regulating the pH value of the digested liquid and final discharging marsh gas sludge. The process of the present invention has raised march gas yield and shortened gas producing period.
