NOVELTY - Heavy metal in municipal sewage sludge is removed by importing residual sludge that is secondary precipitated by municipal sewage plant and the energy material of the acidophilic microbe into sequencing batch reactor, and carrying out the domestication of the indigene acidophilic microbe with aeration. The sludge is exported according to the designed export ratio. The fresh sludge and energy material are mixed with inoculum sludge in the reactor by aeration, and aerated. The concentrated sludge is dehydrated and mixed with alkaline material.    USE - Method is for removal of heavy metal, e.g. copper, zinc, cadmium, nickel, in municipal sewage sludge.    ADVANTAGE - The operation process of the reactor is simplified. The microbe has good activity in the inoculum sludge. The content of the rudimental heavy metal is in accordance with pertinent limit standards in the Pollutant Control Standards of the Agro-Sludge (GB4284-84).    DETAILED DESCRIPTION - Removal of heavy metal in municipal sewage sludge involves importing residual sludge that is secondary precipitated by municipal sewage plant and the energy material of the acidophilic microbe into sequencing batch reactor, and carrying out the domestication of the indigene acidophilic microbe with aeration. When the pH is 2.5, ORP is 500mv, the sludge is exported according to the designed export ratio. The residual sludge having has the abundant acidophilic microbe is used as the inoculum sludge of the reactor running. The fresh sludge is imported into the reactor from secondary precipitation tank by the sludge pump. The energy material is put into the reactor by the measure medicine equipment. The fresh sludge and the energy material are mixed with the inoculum sludge in the reactor by aeration, and carry out the aeration reaction period upon reaching the designed running water level. The treated mud-water mixture is exported into the concentration flow tank according to the designed export ratio with the water power state of aeration stir. The exported mud-water mixture goes into the concentration flow tank, and the sludge concentration and solid liquid separation are carried out. The concentrated sludge is dehydrated and mixed with alkaline material. It is used to the resource utilization. The supernatant fluid in the concentration tank goes into the pH regulating tank, and reflows to the sewage disposal process after it is adjusted the pH to alkali neutral. The high concentration heavy metal grain stillage in the regulating tank is used to the industrial raw material. The additional quantity of the energy substrate is 10g/l sludge when the concentration of the residual sludge is 8-12 g/l. The substrate is ferrite at the room temperature. The export ratio is designed to be 1:1.3 when the strain of the reactor is acidophilic iron protoxide thiobacillus at the room temperature. The operation cycle of the reactor is 1-2 days. The grain stillage in pH regulating tank has iron, zinc, and copper.    DESCRIPTION OF DRAWING(S) - The drawing is a flow diagram of the method.
