Layer air flotation is a type of dissolved air flotation. The equipment integrates condensation, air flotation, skimming, sedimentation and mud scraping. The overall shape is cylindrical, the structure is compact, and the pool is shallow. The main body of the device consists of five parts: the pool body, the rotating water distribution mechanism, the dissolved air release mechanism, the frame mechanism, the water collection mechanism, etc. The water inlet, water outlet and scum discharge outlet are all concentrated in the central area of the pool body. The water distribution mechanism, water collection mechanism and dissolved air release mechanism are all closely connected with the frame and rotate around the center of the pool body. This device provides a complete set of equipment assembly and control system. Through the combination of centralized control and decentralized control, the equipment can achieve optimal operating status.
Process flow
The raw water enters through the central pipe at the bottom of the pool after flocculation and mixing. The scum on the water surface is collected by a skimmer, and then discharged into the central sludge tank and into the matching sludge device. The sludge that sinks to the bottom of the pool is collected by the scraper and discharged into the sludge discharge tank, and the clean water is collected and discharged by the central water collection mechanism. The raw water with good flocculation refers to the raw water formed by adding flocculation agent or effective flocculation reaction in the raw water for several minutes. The specific dosage, flocculation time, and flocculation effect need to be determined based on the on-site water quality and after debugging.
Scope of application
Shallow air flotation is widely used in papermaking wastewater treatment and industrial wastewater treatment. First, it is used to remove algae and reduce turbidity in tap water with lake water as the source. Second, it is used in industrial sewage treatment projects, such as petrochemical, textile, printing and dyeing, papermaking, slaughtering, tanning, food industry and other industries. Third, it is used in sewage. Recycling of useful substances, such as paper making, fiber recycling in white water and other fields.
