Technical Field

[0001] This utility model relates to the technical field of sewage treatment devices, and more specifically, to a forestry sewage treatment device. Background Technology

[0002] The rosin chemical industry is a pillar industry of my country's forest chemical industry and one of the largest-volume forest chemical products. The utilization of rosin resources is based on the extraction of resin from living pine trees. Rosin has excellent properties such as anti-corrosion, moisture resistance, insulation, adhesion, emulsification, and softening, and is widely used in various sectors of the national economy.

[0003] Rosin production generates wastewater. In a wastewater treatment pot in patent CN220684807U, a recycling structure is set on the treatment device to realize the recycling of rosin wastewater and reduce the waste of water resources. However, when replacing or cleaning the filter screen in this patent, it is necessary to disassemble the pipes and pot cover. There are many bolts to disassemble, which is troublesome and affects the replacement efficiency. The device requires a long downtime, which affects the use of the device.

[0004] In view of this, we have studied and improved the existing problems to provide a forest wastewater treatment device, aiming to solve the problems and improve its practical value through this technology. Utility Model Content
