Abstract

The invention provides a fish breeding sewage treatment device, which includes a box body, a sewage inlet is provided on the side of the box body, a blower is installed on the side wall of the box body directly above the sewage inlet, and a water outlet pipe is provided at the upper end of the other side wall of the box body. There is a control panel installed on the outer wall of the box at the bottom. Motors are evenly distributed on the upper end of the box. There is a filter screen inside the box. The filter screen is above the sewage inlet. mouth. By setting the filter screen inside the box, the purification of sewage can be accelerated. The sedimentation area set at the lower end of the filter screen can collect the impurities filtered by the filter screen and discharge them from the slag discharge port set at the bottom of the box body, so that the device has Automatic sewage discharge function, the set blower can infuse gas into the box, make the gas combine with the water in the box, and increase the dissolved oxygen in the water. This device has simple structure, easy operation, fast filtration, good sewage purification effect, and also It can increase the dissolved oxygen in water and is suitable for large-scale promotion.

Description

Technical field[0001]The invention relates to the technical field of environmental protection, in particular to a fish breeding sewage treatment device.Background technique[0002]In people’s aquaculture, the production of sewage is unavoidable. In sewage treatment methods and sewage treatment devices, as general pretreatment methods and pretreatment devices, there have been some methods and devices in the past. As an example, as the front of biological treatment devices The treatment device includes a pre-treatment device for precipitation, filtration, pH adjustment, ozone oxidation, adsorption, etc. The purpose of the pre-treatment device is to reduce the biological, chemical, or physical burden of the wastewater treatment device in the subsequent process Therefore, it can be expected to reduce the scale of the aquaculture sewage treatment device and improve the treatment quality of the treated water from the aquaculture sewage treatment device.[0003]However, when the existing aquac...
