Description

Technical Field

[0001] The invention relates to the technical field of sludge water treatment, and in particular to a method and device for concentrating and purifying sludge water. Background Art

[0002] Domestic sewage refers to wastewater discharged by people in their daily life activities. This kind of wastewater is mainly polluted by domestic waste and human excrement. The amount, composition and concentration of pollutants are related to people's living habits and water consumption. Domestic sewage generally does not contain toxic substances, but it has conditions suitable for the reproduction of microorganisms and contains a large number of bacteria and pathogens. From a health point of view, it has certain hazards. Due to the continuous increase in urban population, the problem of urban domestic sewage treatment has become increasingly prominent. Due to backward technology, lack of funds and difficulty in treatment, it has always affected the urban environment and its construction. If this problem is not solved as soon as possible, If there are some problems, then with the advancement of urbanization and the continuous increase in water consumption, pollution will become more serious and the impact will be more severe. Mud water treatment is a systematic water treatment project, which includes mud water collection, concentration, purification and final dehydration technology and monitoring system. Mud water concentration is the key link in mud water reduction and dehydration and drying treatment. Mud water purification is to recycle water resources. Usually, according to the purpose of mud water treatment, it is necessary to combine multiple water treatment methods to treat it, concentrate and dehydrate the sludge pollutants to improve the mud water concentration rate and ensure the water quality of the effluent.

[0003] However, due to the limitations of its own structure, the existing sewage sludge treatment structure cannot achieve rapid, efficient and continuous separation operations between muddy water and water sources. The efficiency during the separation process is low, and incomplete separation often occurs, requiring repeated mud and water separation treatment operations. At the same time, the equipment is unable to perform sufficient and uniform mixing treatment operations on the flocculants for mud and water separation, which affects the final effect of mud and water separation. The treatment technologies currently used for special muddy water generated in various industrial production processes and shallow muddy water generated in various wastewater treatment processes are limited in their technical and economic feasibility and cannot meet daily use needs. Therefore, it is urgent to design a mud water concentration and purification treatment method and device to solve the above problems. Summary of the invention
