Wastewater treatment device for livestock and poultry farm

Abstract

The invention discloses a wastewater treatment device for a livestock and poultry farm. The wastewater treatment device comprises a base. A cylinder is installed on the base. A top end of the cylinderis opened, and a bottom end of the cylinder is provided with a water outlet. A rotation driving mechanism is installed on the base and positioned at one side of the cylinder. A filtering adsorption mechanism comprises a stand column, an installing frame, and a filtering adsorption part. The stand column is installed on the rotation driving mechanism. The rotation driving mechanism is disposed todrive the stand column to be rotated around a vertical center line of the stand column. The installing frame is upwards and downwards slidably installed on the stand column. The filtering adsorption part is installed on the installing frame. The filtering adsorption part of the wastewater treatment device can be ascended and descended relative to the cylinder. The filtering adsorption part is capable of filtering solid substances in wastewater and adsorbing nitrogen, phosphorous, antibiotics and heavy metal in the wastewater, so a purpose of purifying the wastewater is achieved. The device issimple and rapid in operation, and capable of rapidly and effectively filtering and adsorbing the farm wastewater.

Description

technical field [0001] The invention relates to the technical field of wastewater treatment, in particular to a wastewater treatment device for livestock and poultry farms. Background technique [0002] In recent years, with the adjustment of my country's agricultural structure and the advancement of agricultural industrialization, the large-scale and intensive livestock and poultry breeding industry has developed rapidly and has become an important part of my country's agricultural and rural economy; however, the development of these farms satisfies the It has met the large demand of urban residents for meat, poultry and egg food, and has also become an important source of pollution to pollute water bodies; the annual wastewater discharge of livestock and poultry farming in my country exceeds 10 billion tons, and the nitrogen, phosphorus, and antibiotics contained in livestock and poultry farming wastewater ( Such as sulfonamides, macrolides, and tetracyclines) and heavy meta...
