Description

Technical Field

[0001] The invention relates to the field of wastewater treatment, and in particular to a high-salinity industrial wastewater combined treatment device. Background Art

[0002] High-salinity industrial wastewater refers to industrial wastewater containing high concentrations of soluble inorganic salts (such as chlorides, sulfates, carbonates, etc.), which usually comes from the chemical, pharmaceutical, petrochemical, electroplating, seawater desalination and other industries. This type of wastewater has high osmotic pressure, high conductivity and corrosiveness. If it is directly discharged without effective treatment, it will have a serious impact on the environment and aquatic ecosystems. Therefore, the treatment of high-salinity industrial wastewater requires the use of efficient separation, desalination and concentration technologies to reduce pollution and improve the recycling rate of water resources.

[0003] Chinese patent application number: CN202420520313.9 is a high-salinity industrial wastewater combined treatment equipment, including a filter box and a cover plate arranged on the filter box, two filter plates are arranged in the filter box, and the two filter plates are clamped in the slots opened on the cover plate and the clamping slots opened on the filter box through the clamping assembly. When the filter plate needs to be disassembled for replacement, cleaning or maintenance, the knob is first pressed downward, and the knob applies pressure to the first spring, and the clamping plate slides out of the first clamping slot and the second clamping slot. At this time, the knob is rotated to drive the clamping plate to move in the first installation slot and the second installation slot until the clamping plate slides out of the second installation slot. At this time, the clamping plate does not limit the filter plate, and the filter plate can be pulled out from the slot of the cover plate and the clamping slot in the filter box. After completion, the filter plate is disassembled. This disassembly method saves time and effort, and the maintenance personnel do not need to disassemble the entire filter box, which greatly simplifies the maintenance process, improves operating efficiency, and reduces manpower and time costs.
