Wastewater recovery device for livestock and poultry aquaculture and recovery method thereof

Abstract

The invention discloses a wastewater recovery device for livestock and poultry aquaculture. The wastewater recovery device comprises a bottom plate, and the upper surface of the bottom plate is welded with a draining bucket. Garbage in wastewater is filtered, then chemicals are added into the wastewater from which large-volume impurities are filtered out for treatment, then precipitation is carried out, solid-liquid separation is started, separated clear liquid is filtered twice, the clear water is discharged into a water environment for culturing aquatic products from a drain pipe, and the wastewater is recycled after being treated, so that direct discharge is avoided, and a relatively good environment-friendly effect is achieved. Garbage in wastewater is filtered by using a filter box, when the volume of the filter box is full of the garbage collected in the filter box, an electric push rod is started to drive a connecting plate to ascend and descend, the connecting plate drives one side of the filter box to ascend upwards, and the garbage in the filter box is poured out from a discharging pipe, so that the problem that large-size garbage exists in the wastewater is solved; and therefore, the problem that the aquaculture wastewater treatment speed is low is solved.

Description

technical field [0001] The invention relates to the technical field of wastewater recovery for aquaculture, in particular to a wastewater recovery device for livestock and poultry aquaculture and a recovery method thereof. Background technique [0002] Wastewater is mainly divided into domestic wastewater and industrial wastewater. With the continuous improvement of people's living standards and environmental protection awareness, people have paid more and more attention to saving water resources. In life, we use water everywhere, such as washing vegetables, cooking Meals, laundry, bathing, flushing the toilet, mopping the floor, etc., every time a life step is completed, a lot of sewage may be generated. Livestock aquaculture is the production activity of breeding, cultivating and harvesting aquatic animals and plants under human control. Generally, it includes the whole process of growing aquatic products from seedlings under artificial breeding management, and in a broad...

AI Technical Summary

Problems solved by technology

[0003] 1. When the existing aquaculture wastewater treatment device treats aquaculture wastewater, it simply adds some drugs and then discharges it into the water environment. The treatment effect is not obvious, and it will still have a certain impact on the water environment. , not conducive to the protection of the water environment;

[0004] 2. When the existing aquaculture wastewater treatment device is processed again, the garbage in the aquaculture wastewater is not treated in the continuous treatment process, resulting in a slower treatment speed of the aquaculture wastewater. For this reason, a livestock and poultry wastewater treatment method is proposed. Aquaculture waste water recovery device and recovery method thereof
