Description

Technical field

[0001] The invention relates to a filter device of a sewage treatment vehicle. Background technique

[0002] As the water pollution problem continues to aggravate and the requirements for environmental quality become increasingly stringent, the treatment and recycling of sewage has become an increasingly important part of environmental and resource protection. Existing sewage treatment plants transport scattered domestic sewage through long-distance transportation and then centralized treatment. This treatment method is not only ineffective, but also consumes a lot of transportation costs. The treatment workshop cannot achieve mobile operations.

[0003] In order to solve this problem, different types of sewage treatment vehicles have emerged. For example, the utility model of authorized announcement number CN 201473395 U discloses a septic tank sewage treatment equipment, which is intercepted by a filter, vacuum suction and centrifugal sedimentation. For sewage se...
