Small and Medium sized Enterprise Entrepreneurship Base in Longdu Street, Zhucheng City, Shandong Province

I. Overview

The CXAF series air flotation sewage treatment equipment is a newly developed product introduced by our company with foreign technology, and has obtained the Shandong Province Environmental Protection Product Use Certification. The system has a COD and BOD removal rate of over 85% and a SS removal rate of over 90%. It has the advantages of low energy consumption, high efficiency, economical operation, simple operation, low investment cost, and small footprint. It is widely used in the standard treatment of industrial and urban wastewater in industries such as papermaking, chemical, printing and dyeing, refining, starch, and food

2、 Structure of CXAF cavitation air flotation equipment

1. The CXAF vortex concave air flotation equipment mainly includes an air flotation box, vortex concave aerator, chain scraper system, floating slag collection and discharge system, overflow water system, electric control system, dispensing tank, storage tank, glass rotor flowmeter, reflux pipeline, circular operation platform, and dosing pump.

2. The equipment casing can be a solid steel plate structure, or our company can provide the casing drawings. After the user builds their own concrete structure, our technical personnel will guide the installation on site. It is recommended that when the water processing capacity of a single machine exceeds 320m³/At h, the box is made of reinforced concrete structure.

4CXAFWorking principle of vortex concave air flotation equipment

1. The pollutants in sewage are divided into dissolved organic matter and insoluble substances (i.e. SS). Dissolved organic matter can be converted into non soluble substances under certain conditions. One of the methods of sewage treatment is to add coagulants and flocculants to convert most of the dissolved organic matter into non soluble substances, and then remove all or most of the non soluble substances (i.e. SS) to achieve the purpose of purifying sewage. The main method of removing SS is to use air flotation.

2. CXAF is the process of air flotation generated by air. The vortex concave aerator directly injects "microbubbles" into the sewage without the need for pre aeration, and then evenly distributes the "microbubbles" in the sewage through precision cast stainless steel diffuser impellers, so there will be no blockage. This equipment does not require auxiliary equipment such as pressure vessels, air compressors, and circulation pumps.

3. Untreated sewage first enters the aeration and inflation section, where it is fully mixed with "microbubbles". As the "microbubbles" rise, they carry suspended solids to the water surface. The scraper moves along the liquid surface, scraping suspended solids onto a tilted metal plate, and then pushing them into the sludge discharge pipeline. There is a horizontal screw propeller in the sludge discharge pipeline, which sends the collected sludge into the sludge collector. The propeller and scraper are driven by the same motor. The purified sewage will pass through the overflow tank under the inclined plate before discharge. The overflow tank is used to control the water level of the air flotation tank, ensuring that the liquid in the tank does not flow into the sludge discharge pipeline.

4. The open reflux pipeline extends from the aeration section along the bottom of the air flotation tank. At the same time as generating microbubbles, the vortex concave aerator will form a negative pressure zone at the bottom of the tank with a return pipe. This negative pressure will cause water to flow back from the bottom of the tank to the aeration zone, and then return to the air flotation section. A one-way valve is installed on the return pipe to prevent sewage entering the aeration tank directly from the return pipe without treatment. The entire process ensures that air flotation continues without any inflow.
