Sewage treatment device for cultivation greenhouse

Abstract

The invention discloses a sewage treatment device for a cultivation greenhouse. A primary sedimentation chamber is arranged at one side of a device body; a sewage inlet is arranged at the top end of the left side of the primary sedimentation chamber; a blow-off opening is formed in the bottom end in the primary sedimentation chamber; a sludge chamber is mounted at the bottom of the blow-off opening; a sludge cleaning device is mounted at the right side in the sludge chamber; an electric cylinder is arranged at one end of the sludge cleaning device; a push plate is mounted at one end of the electric cylinder; a sludge outlet is arranged at the left side of the sludge chamber; a biochemical chamber is mounted at the right side of the primary sedimentation chamber; a secondary sedimentation chamber is mounted at the right side of the biochemical chamber; a disinfection chamber is mounted at the right side of the secondary sedimentation chamber; a control box is mounted at the top end of the right side of the disinfection chamber; a clean water outlet is formed in the bottom end of the right side of the disinfection chamber. According to the sewage treatment device disclosed by the invention, the electric cylinder and the push plate are fixedly connected through a fastening part and are firm; the push plate can be used for cleaning sludge in the sludge chamber under the action of the electric cylinder and is flexible and rapid; normal work of the device body is ensured and the working efficiency of the device is improved; the burdens of workers are alleviated and the post-period cleaning cost is saved.

Description

technical field [0001] The invention relates to the technical field of a sewage treatment device, in particular to a sewage treatment device for aquaculture greenhouses. Background technique [0002] With the accelerated transformation of domestic farming methods from family free-range farming to large-scale farming, the pollution caused by farming is also increasing. Untreated farming sewage is directly discharged into the water body, which will not only make the water smelly, destroy the dynamic balance of the water body, and affect The surrounding environment will also cause the groundwater to be polluted, which in turn poses a threat to people's life and health. In order to avoid this phenomenon, sewage treatment equipment is generally used to treat aquaculture sewage. Most of the existing sewage treatment equipment has complex structures, not only occupying an area The area is large, the construction cost is high, and it is inconvenient to maintain and manage.

[0002] With the accelerated transformation of domestic farming methods from family free-range farming to large-scale farming, the pollution caused by farming is also increasing. Untreated farming sewage is directly discharged into the water body, which will not only make the water smelly, destroy the dynamic balance of the water body, and affect The surrounding environment will also cause groundwater to be polluted, which in turn poses a threat to people's life and health. In order to avoid this phenomenon, sewage treatment equipment is generally used to treat aquaculture sewage. Most of the existing sewage treatment equipment has complex structures, not only occupying an area The area is large, the construction cost is high, and it is inconvenient to maintain and manage. It is very unsuitable for small-scale farms. In addition, most sewage treatment devices use mains electricity to work, which has high operating costs and poor practicability.
