Description
Technical field
The utility model relates to a kind of Sludge Chemical Conditioning concentration systems, belongs to technical field of sludge disposal.
Background technology
Along with the quantity discharged of urban industry waste water and sanitary sewage is increasing, treatment rate of domestic sewage also improves year by year, the sludge yield of municipal sewage plant also sharply increases, a large amount of excess sludges will discharge in sewage work, the mud of enormous amount needs to do further process, if mud can not get reasonable process, secondary pollution will be caused.According to statistics, the process disposal costs of sewage sludge is higher, in whole construction costs of sewage work, about accounting for five/mono-to half for the treatment of the expense of mud.The composition of sewage sludge is very complicated, except containing except a large amount of moisture, also containing a large amount of useful resources.At present urban sludge treating method is had multiple, generally have landfill, burning and comprehensive utilization, but before recycling, pre-treatment need be carried out to mud, carry out cracking conditioning etc., comprise concentrated, dehydration, dry.In the mud gravity concentration tank of sewage work, mud is by after natural subsidence gravity concentration, remove the free water in mud, mud needs to carry out decrement disposal, containing microorganism in mud, anaerobic digestion time is a very long process, acidication speed is very slow, and therefore mud needs to carry out cracking process, accelerates mud organic substance release.
Utility model content
The purpose of this utility model is to provide a kind of Sludge Chemical Conditioning concentration systems, native system is integrated with chemical conditioning acidifying, oxidation, coagulation process, by cracking the microorganism in mud, accelerate mud organic substance release, the mud cracked is easy to dehydration, water extracter energy consumption reduces, and mud has germicidal action by oxidation simultaneously.
The purpose of this utility model is achieved through the following technical solutions: the utility model forms primarily of the acidizing device connected successively, oxidizing tower, coagulation device, sludge pre-thickening machine and centrifuge; It is characterized in that: the dosing mouth of described acidizing device is connected with means for feeding acid by pipeline; The dosing mouth of described oxidizing tower is connected with oxygenant throwing device by pipeline; The dosing mouth of described coagulation device is connected with coagulant dosage device by pipeline; Described acidizing device, oxidizing tower and coagulation device are all provided with stirrer.
The top venting port of described oxidizing tower is connected with exhaust gas treating tower by pipeline.
The below of described sludge pre-thickening machine is provided with concentrated solution collection bucket, and concentrated solution collection bucket is connected with acidizing device advance water pipe by circulation tube, and is provided with recycle pump on circulation tube.
Utility model works principle: in the mud gravity concentration tank of sewage work, mud is by after natural subsidence gravity concentration, remove the free water in mud, mud needs to carry out decrement disposal, containing microorganism in mud, anaerobic digestion time is a very long process, and acidication speed is very slow, and therefore mud needs to carry out cracking process, chemical conditioning acidifying, oxidation, coagulation process, accelerate mud organic substance release.Mud is by conditioning acidifying, add the acidizing fluids such as sulfuric acid, mud PH reduces, in oxidizing tower, add the strong oxidizers such as hydrogen peroxide, cell content is released, and kill bacterium in mud, thus significantly improve the content of protein in mud, carrying out fast of facilitation of hydrolysis, partial concentration liquid is circulated by recycle pump, and all the other mud enter centrifuge and carry out processed.
In sum, the beneficial effects of the utility model are: native system is integrated with chemical conditioning acidifying, oxidation, coagulation process, by cracking the microorganism in mud, accelerate mud organic substance release, the mud cracked is easy to dehydration, water extracter energy consumption reduces, and mud has germicidal action by oxidation simultaneously, is convenient to carry out recycling.
