Abstract

The invention provides a pollutant treating system relating to the technical field of pollutant treatment. The pollutant treating system comprises a sludge tank, a first pump, an electrolysis adjusting barrel, a second pump, an electric flocculation device and a pressure filter, wherein the sludge tank is connected with the adjusting barrel by the first pump and is used for storing sludge to be treated and conveying the sludge to be treated into the electrolysis adjusting barrel; the electrolysis adjusting barrel is connected with the electric flocculation device by the second pump and is usedfor adding chloride ion electrolyte into the sludge to be treated and pumping the sludge to be treated in the electrolytic adjusting barrel into the electric flocculation device by the second pump; the electric flocculation device is used for electrolyzing the sludge to be treated under the condition that the current density is 50-400A by utilizing internal iron or aluminum positive and negativeelectrodes, conveying the electrolyzed sludge into the pressure filter; and the pressure filter is used for filtering the electrolyzed sludge, and then solid sludge and filtrate are obtained. The pollutant treating system provided by the invention solves the problem that the sludge emission causes pollution to the environment.

Description

technical field [0001] The invention belongs to the technical field of pollutant treatment, in particular to a sludge treatment method and system. Background technique [0002] With the development of social economy and urbanization in our country, the generation and quantity of urban sewage and sludge are constantly increasing. It is estimated that by 2020, the output of municipal sewage and sludge in my country will reach 60 million tons to 90 million tons, and the annual growth rate will be greater than 10%. [0003] At present, sewage and sludge in most cities are not treated, and are directly discharged into the environment. Among them, a large number of pollutants contained in sludge include pathogenic microorganisms, parasite eggs, nitrogen and phosphorus, organic pollutants, heavy metals and salt, which are harmful to the environment. create pollution. Contents of the invention [0004] The invention provides a sludge system aimed at solving the problem of enviro...
