Abstract

A sludge heavy metal biochemical treatment tank comprises a first tank body, a first flow guiding cover arranged in the first tank body and an air blowing mechanism. The first tank body is provided with a first feed port used for putting in sludge raw materials containing heavy metal, a first feed inlet for putting in a nutrient solution containing thiobacillus thiooxidant and a first ventilation port communicated with the air blowing mechanism. The first ventilation port is located at the bottom of the first tank body. The first flow guiding cover comprises a first upper opening, a first lower opening located over the first ventilation port and a first drainage channel extending to the first upper opening from the first lower opening. By means of the sludge heavy metal biochemical treatment tank, heavy metal and thiobacillus thiooxidant of sludge can have a full gas and solid contact effect, the heavy metal is dissolved out of the sludge because of the oxidization and acidification effect of the thiobacillus thiooxidant, and the heavy metal in the sludge is removed.

Description

technical field [0001] The invention relates to a sludge treatment auxiliary equipment, in particular to a sludge heavy metal biochemical treatment tank body. Background technique [0002] In recent years, with the rapid growth of my country's sewage treatment capacity and treatment rate, a large amount of excess sludge has been produced. At present, only a small part of the sludge from urban sewage treatment plants in the country is used for sanitary landfill, land utilization, incineration and building material utilization, etc., and most of them have not undergone standardized treatment and disposal. The heavy metals contained in excess sludge are non-degradable. If they are transported out, simply landfilled or piled up without effective treatment and disposal, they will easily cause persistent pollution to groundwater and soil, directly threatening environmental safety and public health. [0003] Heavy metals in sludge mainly include Pb, Cd, Hg, Cr, Ni, Cu, Zn, etc., a...
