Sewage treatment and recycling device

Abstract

The invention belongs to the field of water treatment projects, and specifically discloses a sewage treatment and recycling device which comprises an impurity clearing barrel, wherein a cover plate isarranged on the impurity clearing barrel; the cover plate is communicated with a feed pipe and a water inlet pipe; the back-to-back sides of the feed pipe and the water inlet pipe are respectively provided with a through groove; an insertion plate for blocking the feed pipe and the water inlet pipe is in slip connection in each through groove; two polar plates facing each other along the diameterare arranged on the inner wall of the impurity clearing barrel; the sewage treatment and recycling device also comprises a power supply connected with the polar plate; two vibrating plates facing each other along the diameter are also arranged on the inner wall of the impurity clearing barrel; an arc bulge is arranged on the inner side of each vibrating plate; the vibrating plates are connected with the inner wall of the impurity clearing barrel through springs; the bottom of the impurity clearing barrel is communicated with a collection box below the vibrating plates; the outer side of eachvibrating plate is connected with a connecting rod; the ends, away from the vibrating plate, of the connecting rods are respectively connected with the insertion plate; a rotary drum is coaxially androtatably connected in the impurity clearing barrel. By adopting the scheme, the sewage treatment effect is better, and the efficiency is higher.

Description

technical field [0001] The invention belongs to the field of water treatment engineering and specifically discloses a sewage treatment and recycling device. Background technique [0002] Sewage treatment refers to the process of purifying sewage to meet drainage requirements or water quality requirements for reuse. Alum is usually used to purify water in daily life. Alum is ionized in water to produce aluminum ions, and the aluminum ions are hydrolyzed to form colloidal aluminum hydroxide. Aluminum hydroxide colloid has a strong adsorption capacity, which can absorb suspended impurities in water and form precipitates. The water is clear. [0003] The sewage treatment device in the prior art includes an impurity cleaning bucket. The impurity cleaning bucket is provided with a cover plate, and the cover plate is connected with a feed pipe and a water inlet pipe. When in use, alum is sent from the feed pipe into the impurity cleaning bucket. Sewage is sent from the water inle...
