Abstract
A sewage treatment device capable of recovering methane and ammonia simultaneously comprises an up-flow type anaerobic sludge bed unit and a baffle plate ion exchange unit, wherein the up-flow type anaerobic sludge bed unit and the baffle plate ion exchange unit are connected sequentially; the up-flow type anaerobic sludge bed unit comprises a reaction zone, a three-phase separator, a settling zone and a gas collecting chamber from bottom to top; a water inlet pipe is arranged at the bottom of the left side of the reaction zone, and a sludge discharge port is formed in the bottom of the middle; a gas outlet is formed in the gas collecting chamber; the baffle plate ion exchange unit is divided into multiple separate compartments arranged horizontally by multiple vertical baffle plates; the structure that a falling zone in the front and a rising zone at the back are connected in series alternately is formed in each separate compartment by the aid of the baffle plate; the rising zones of the baffle plate ion exchange unit are filled with zeolite ion exchangers. The device is compact in structure, anaerobic methane production and subsequent zeolite ion exchanging are combined, and energy and nitrogen elements are recovered while sewage is treated.
