1. an exhaust treatment system for combined bio method, the circulating filtration water tank there is a biological treatment tank, being disposed below, the purification air pipe being positioned above;

  • It is characterized in that;

    Have horizontally disposed second level biological filter bed, spray equipment layer, first order biological filter bed inside described biological treatment tank from top to bottom, waste gas enters space, liquid refluxes space;

    There is below its side UNICOM'"'"'s waste gas and enter the waste gas air source inlet in space, there is above its side the pH value adjusting means of UNICOM'"'"'s second level biological filter bed;

    There is on the upper case of described circulating filtration water tank its internal refluxing opening of UNICOM;

    There is on the lower case of circulating filtration water tank its internal and spray equipment layer liquid of UNICOM and pump mouth, UNICOM'"'"'s pipeline has pumping installations;

    Also having defecator inside circulating filtration water tank, circulating filtration water tank is divided into two spaces by defecator, refluxing opening with pump mouth on the different both sides of defecator so that the liquid of backflow pumps removing after filtering again;

    Described biological treatment tank top has purified gas outlet, and UNICOM purifies air pipe, purifies air pipe by sucktion fan UNICOM evacuation port;

    Active biological inoculum in described first order biological filter bed, wherein bacteriophage kind is the most active;

    The described second level active biological inoculum of biological filter bed, in active bio strain therein, non-sulfur strain is more the most active.
