The utility model discloses a mud pyrohydrolysis and anaerobic digestion integrated process process systems, this process systems is by advancing the mud sump, the sludge pipe, advance the dredge pump, the sludge thickening machine, the pulp jar, stirring vane, the (mixing) shaft, a weighing sensor and a temperature sensor, agitator motor, pressure sensor, the pyrohydrolysis retort, load nickel based catalyst's pyrohydrolysis catalysis pipe, steam generator, pressure relief tank, the steam storage tank, the advanced oxidation retort, the ozone pipe, load the ozone catalysis pipe of titanium base catalyst, a diving pump and an ozone generator, digester tank, filter press, go out the mud sump, methane gas body coupling pipe and methane gas body storage tank are formed. The beneficial effectsof the utility model are that, the processing of being applied to mud with this mud pyrohydrolysis and anaerobic digestion integrated process process systems have the energy consumption hang down, kill the germ can the reinforce, good, the dry mud production volume of sludge dewatering performance less, in the marsh gas high, the hydrogen sulfide content low grade advantage of methane gas body burden.
