The invention discloses a
new energy automobile battery
recovery environment-friendly
sewage treatment device which is characterized in that a
water storage tank is fixed in a treatment box, a
chemical storage box is fixed at the top of the treatment box, a chemical feeding hole communicated with the interior of the treatment box is formed in the bottom of the
chemical storage box, the chemical feeding hole is connected with a chemical conveying
pipe, and one end of the chemical conveying
pipe is arranged above the
chemical storage box; a drainage
pipe is connected to the bottom of the
water storage pond and penetrates through the
water storage pond, a mesh screen is arranged at the top of the drainage pipe, first screen cloth is arranged in the mesh screen, a collecting column is in threaded fit with the bottom of the water storage pond, a circular groove is formed in the collecting column, and the end, away from the water storage pond, of the drainage pipe is arranged in the circular groove. A plurality of staggered first drainage holes are formed in the two baffles,
second screen cloth is fixed to the first drainage holes, a plurality of second drainage holes communicated with the circular groove are formed in the side wall of the top of the collecting column, and the problems that a large number of
metal precipitates and impurities are carried in
