Description

Technical Field

[0001] The utility model mainly relates to the technical field of wastewater treatment, and particularly relates to a wastewater separation device for the production of dibutyl phthalate. Background Art

[0002] The wastewater treatment methods for wastewater containing dibutyl phthalate mainly include three types of treatment measures: physical treatment, chemical treatment, and biological treatment. Usually, the three treatment measures are selected to work together. The physical treatment is used in the first stage of the wastewater treatment of dibutyl phthalate, and large particulate impurities and suspended matters existing in the wastewater can be removed.

[0003] The existing patent (publication number: CN220056438U) discloses an organic wastewater circulation filtration device, which includes a box body and a box cover. A water inlet pipe is fixedly arranged at the top of the box body, a filter screen is fixedly arranged inside the box cover, the water pumping end of a circulation pump is communicated with a circulation cavity, the water drainage end of the circulation pump is communicated with a return cavity, a plurality of filter plates are fixedly arranged on the outer wall of a filter cylinder, and a plurality of activated carbon filter holes are fixedly arranged on the filter plates. First, the organic wastewater is added into the box body from the water inlet pipe, and the organic wastewater can be preliminarily filtered through the filter screen. The harmful substances in the organic wastewater can be filtered again through the activated carbon particles in the filter cylinder. The water after preliminary filtration enters the circulation cavity from the water outlet hole, and the water in the circulation cavity can be pumped into the return cavity through the circulation pump. At the same time, the high-pressure water flow drives the driving blades to rotate, the driving blades drive the filter cylinder to rotate, the filter cylinder drives the filter plates to rotate, and the organic wastewater can be stirred and filtered through the activated carbon filter holes, thus greatly improving the purification ability of the organic wastewater.

[0004] In the process of implementing this solution, the inventor considered that consumables such as activated carbon particles need to be replaced during use. Referring to the current equipment structure, when replacing the activated carbon and other filter consumables, a large number of structural disassembly and assembly operations are required for the equipment to replace the activated carbon consumables in structures such as the filter cylinder and filter plates. That is, there is a technical problem that the filtration operation of filter consumables is inconvenient during the use stage of the current equipment. Summary of the Utility Model
