Sewage treatment system for aluminum plastic waste recovery production

Abstract

The invention discloses a sewage treatment system for aluminum-plastic waste recovery production, and belongs to the technical field of aluminum-plastic waste recovery production, the sewage treatment system comprises a water inlet channel, a sedimentation tank is connected behind the water inlet channel, a first filter frame is arranged in the water inlet channel, the first filter frame is of a structure with an opening at the front end and a rear baffle at the rear end, and the rear baffle is of a net plate structure; the interior of the sedimentation tank is divided into a first sedimentation chamber and a second sedimentation chamber through a partition plate, and a liftable filter plate is arranged on the partition plate; a water outlet is formed in a rear wall plate of the second deposition chamber, a liftable water outlet baffle is arranged at the water outlet, and the water outlet baffle is connected with the filter plate through a connecting plate; a water inlet pipe with a top opening is connected behind the second deposition chamber, the lower end of the water inlet pipe is communicated with a horizontally arranged water outlet pipe, a second filter frame and an activated carbon frame are sequentially arranged in the water outlet pipe, and filter plate assemblies are arranged at the bottom of the second filter frame in an array mode.

Description

technical field [0001] The invention relates to the technical field of aluminum-plastic waste recycling production, in particular to a sewage treatment system for aluminum-plastic waste recycling production. Background technique [0002] Aluminum-plastic packaging bag, also known as aluminum-plastic bag, aluminum-plastic composite bag, etc., is a kind of aluminum-containing plastic packaging product, with low cost, exquisite printing, anti-static, anti-ultraviolet, moisture-proof, oxygen-proof and light-shielding, cold-resistant, oil-resistant, high-temperature resistant, fresh-keeping It has the characteristics of strong oxygen barrier and easy sealing. It is used in various fields such as industrial packaging, daily chemical packaging, food packaging, medicine, hygiene, electronics, aerospace, science and technology, and military industry. Common aluminum-plastic bag products in life include vacuum food packaging bags, beverage bags with self-supporting nozzles, high-temp...

AI Technical Summary

Problems solved by technology

[0004] However, once the sewage treatment system is in use, it will be in a full-load operation state once it is turned on, and it cannot be finely regulated according to the sewage flow to reduce power consumption and improve the utilization rate and service life of the filtration equipment.

In addition, it is inconvenient to replace the filter equipment of the existing sewage treatment system, which is also a problem that needs further improvement.
