Filtering device for ocean sewage treatment

Abstract

The invention discloses a filtering device for ocean sewage treatment, and relates to the technical field of ocean sewage treatment. The filtering device for sewage ocean treatment comprises a device main body, and a water inlet pipe and a water outlet pipe are fixed to the left side and the right side of the device main body respectively. According to the filtering device for sewage ocean treatment, the filtering effect of the filtering device can be improved by arranging multiple rotatable filtering plates, meanwhile, the pressure between the filtering plates and plastic foam balls is small under the rotating filtering effect of the multiple filtering plates, and the situation that the plastic foam balls are extruded to deform and penetrate through filtering holes is prevented. The plastic foam balls on the filtering plate can be stored through a Y-shaped barrier plate, and the Y-shaped barrier plate is matched with a collecting device to enable the plastic foam balls to move into the collecting device, so that the plastic foam balls on the filtering plate are automatically collected, and only the plastic foam balls in the collecting device need to be regularly cleaned, and the filtering plate does not need to be detached, so that the cleaning frequency of the filtering plate is reduced.

Description

technical field [0001] The invention relates to the technical field of marine sewage disposal, in particular to a filter device for marine sewage disposal. Background technique [0002] Sewage marine disposal refers to the discharge of sewage from land treatment facilities into the ocean from underwater through the discharge system. It is a technology that rationally utilizes the environmental capacity of the ocean, and transports the treated (usually primary treatment) sewage to a certain distance from the shore through submarine pipelines, and discharges it through porous diffusers. Prevent and control marine pollution, protect marine resources, maintain sustainable use of the ocean, maintain marine ecological balance, and protect human health. [0003] In the primary treatment of sewage, the larger impurities in the water will be filtered. However, there are a large number of plastic foam balls used to form foam boards in some industrial wastewater. These plastic foam ba...

Problems solved by technology

[0003] In the primary treatment of sewage, the larger impurities in the water will be filtered. However, there are a large number of plastic foam balls used to form foam boards in some industrial wastewater. These plastic foam balls are soft and easy to be compressed, so they may pass through The filter screen cannot be filtered well, and the filter screen needs to be cleaned within a short period of time, and the cleaning frequency is high, which increases the cost of manpower and material resources
