Energy-saving sewage treatment device and method

Abstract

The invention discloses an energy-saving sewage treatment device and method, and relates to the technical field of sewage treatment devices.The energy-saving sewage treatment device comprises an outer box body, a water collecting tank is fixed to one side of the outer box body, a plurality of sewage pipes are connected to the other side of the water collecting tank, a fishing opening is connected to one side of the upper end of the outer box body, and a material injection opening is formed in the other side of the fishing opening. According to the energy-saving sewage treatment device and method, an arc-shaped rod and a door shaft hinge are arranged and can rotate by pushing a push plate through sewage, so that the arc-shaped rod actively opens an inner cavity of a sewage collection bag through rotation, damage caused by opening of the sewage collection bag due to water flow impact is smaller, and the arc-shaped rod and the push plate transversely penetrate through an inlet of the sewage collection bag, so that the sewage treatment effect is better. The large dirt extruded from the coarse screen can be further intercepted, the dirt is prevented from penetrating through the dirt collecting bag due to the large mass, the flexible contact ball can reduce the puncture force of the top end when the arc-shaped rod opens the dirt collecting bag, the pressure intensity of the contact point is reduced, and the pulling damage when the dirt collecting bag is opened due to impact is further reduced.

Description

technical field [0001] The invention relates to the technical field of sewage treatment devices, in particular to an energy-saving sewage treatment device and method. Background technique [0002] Slaughter wastewater comes from the washing, rinsing, slaughtering and other plant floor washing, scalding, dissection and reprocessing of the breeding base. The slaughter wastewater mainly contains blood, grease, bone and meat residue, hair and feces. The composition of slaughter wastewater is relatively complex. The wastewater has a reddish-brown color due to the blood component, has a strong stench, and has a high content of organic matter, so it is prone to corruption. If these wastewater is directly discharged into the external water body, it will affect the ecosystem of the external water body. Huge damage is caused, and the pollution of the environment is also relatively serious. [0003] The existing sewage treatment device partly uses the sewage bag to pretreat the sewage...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides an energy-saving sewage treatment device and method, which solves the problem that the existing sewage treatment device in the above-mentioned background technology partially uses a sewage bag to pretreat sewage during use, and the sewage collection When the bag is not in the water, it is usually in a state of contraction and drooping. After the sewage enters, the violent water flow will impact the sewage bag, causing the sewage bag to expand and open instantly. In this way, the reciprocating sewage bag is easy to be impacted by the water flow and pass through the large Dirt leads to perforation and breakage, a problem that seriously reduces service life
