Nitrogen and phosphorus removal device for water treatment

Abstract

The invention discloses a nitrogen and phosphorus removal device for water treatment. The device comprises a treatment box and a water collection box, the water collection box is located on one side of the treatment box, a limiting frame and a mounting frame are arranged in the treatment box, sliding grooves are formed in the surfaces of the two sides in the treatment box, and the mounting frame is located at the top end of the limiting frame; sliding blocks are fixedly connected to the surfaces of the two sides of the mounting frame, a second rolling wheel is arranged in one side of the sliding groove, the sliding blocks and the second rolling wheel are located in the sliding groove, connecting blocks are fixedly connected to the middle of the two sides of the top end of the mounting frame, and mounting blocks are fixedly connected to the middle of the two sides of the top end of the treatment box; a first roller is arranged in the top end of each mounting block, and the first roller is rotationally connected with each mounting block through a rotating rod; sliding blocks are additionally mounted on the two sides of the mounting frame correspondingly, under the action of the second rolling wheels and the sliding blocks, the ascending stability of the mounting frame is guaranteed, the situation that the mounting frame and the inner wall of the treatment box are clamped is avoided, and a worker can replace the filter screen conveniently.

Description

technical field [0001] The invention belongs to the technical field of water treatment, and in particular relates to a nitrogen and phosphorus removal device for water treatment. Background technique [0002] At present, industrial wastewater contains a large amount of nitrogen and phosphorus, specifically, the wastewater contains a large amount of NH 4 + and PO 4 3- After the industrial wastewater containing these components is discharged, it will cause great harm to the environment. Therefore, it is necessary to denitrify and dephosphorize the industrial wastewater through a denitrification and dephosphorization device to reduce the possible harm of industrial wastewater to the environment. However, there are still various problems in various nitrogen and phosphorus removal devices on the market. [0003] For example, the denitrification and dephosphorization device disclosed in the patent whose authorization notification number is CN209456161U has improved its process...
