NOVELTY - Integrated system comprises an inner chamber (29) which is provided with sequentially arranged waste storage bin (1), an uniform feeding device (2), a first-stage magnetic separator (3), a first-stage crusher (4), a second-stage magnetic separator, a first-stage treatment tank, a second-stage crusher, a second-stage treatment tank, a punching machine, a third-stage magnetic separator, an anaerobic acidification tank, a screening device, an adjustment buffer tank, a deepening anaerobic tank and a sludge sedimentation tank.    USE - The integrated system is useful for domestic solid waste treatment and resource utilization (claimed).    ADVANTAGE - The system: is environmentally friendly (claimed) and economical; does not require waste classification and screening throughout the process; overcomes the restriction of large bottleneck waste disposal; and completely solves the problem of recycling the waste plastic, chemical fiber and other non-waste material, and thus achieves complete waste resources recycling.    DETAILED DESCRIPTION - Integrated system comprises an inner chamber which is provided with sequentially arranged waste storage bin, an uniform feeding device, a first-stage magnetic separator, a first-stage crusher, a second-stage magnetic separator, a first-stage treatment tank, a second-stage crusher, a second-stage treatment tank, a punching machine, a third-stage magnetic separator, an anaerobic acidification tank, a screening device, an adjustment buffer tank, a deepening anaerobic tank and a sludge sedimentation tank. The inner chamber is further internally set with a precipitate cleaning device and a biogas release tank. The inner chamber is externally set with a water supplement tank and a biogas collection tank. The precipitate discharge port of first-stage treatment tank, second-stage treatment tank and anaerobic acidification tank are connected to precipitate cleaning device via feeding device. The supernatant outlet of precipitate cleaning device is connected to the liquid inlet of anaerobic acidification tank. The precipitate cleaning device is connected to the water supplement tank. The liquid outlet of first-stage treatment tank, second-stage treatment tank is connected to the liquid inlet of anaerobic acidification tank via pipeline. The supernatant outlet of the deepening anaerobic tank and biogas release tank is connected to the liquid inlet of first-stage treatment tank, second-stage treatment tank and anaerobic acidification tank via pipeline. The gas outlet of anaerobic acidification tank, adjustment buffer tank, deepening anaerobic tank, sludge sedimentation tank and biogas release tank is connected to the biogas collection tank via pipeline. The inner chamber is provided with two channel gates, where the waste storage bin is set between the two channel gates. The biogas collection tank is set with a boiler and a gas generation unit. The adjustment buffer tank is internally set with a heat exchanger. The thermal medium of heat exchanger is obtained from cooling water and exhaust gas of gas generation unit.
