High Efficiency Dissolved Air Flotation Equipment For Wastewater Treatment

■ Structure

The main body of the equipment is a rectangular steel structure. The main components are composed of dissolved air pump, air compressor, dissolved air tank, rectangular box, air flotation system, mud scraping system, etc.

1. The dissolved gas tank produces small bubbles with a particle size of 20-40um, which adheres to the flocs firmly, and can achieve a good air flotation effect;

2. The amount of flocculant used is small, and the cost is reduced;

3. The operating procedures are easy to master, the water quality and quantity are easy to control, and the management is simple.

Parameters

■ Technical Process

The dissolved gas tank produces dissolved gas water, and the dissolved gas water is released to 5 cubic meters of water to be treated by the decompression of the release device. The air dissolved in the water is released from the water to form tiny bubbles of 20-40um, which combine with the suspended matter in the sewage to make the specific gravity of the suspended matter less than water, and gradually float to the water surface to form scum. There is a scraper system on the water surface to scrape the scum into the sludge tank. The clean water enters the clean pool from the bottom through the overflow tank.

■ Main Features

Air flotation is a dissolved air system that generates a large number of fine bubbles in the water, so that the air adheres to the suspended particles in the form of highly dispersed tiny bubbles, resulting in a state where the density is less than that of water. The principle of buoyancy is used to make it float on the water surface to achieve solid- Liquid separation water treatment equipment. Air flotation is divided into super-effect shallow air flotation, vortex-concave air flotation, and advection air flotation. At present, it has applications in water supply, industrial wastewater and urban sewage treatment. The advantages of air flotation are its solid-liquid separation equipment has the characteristics of low investment, small floor space, high degree of automation, and convenient operation and management.

Combustion process and brief description:
The waste is manually put into the primary combustion chamber of the furnace body, and the automatic temperature control starts the primary combustion. According to the principle of combustion three T (temperature, time, vortex), it is fully oxidized, pyrolyzed and burned in the furnace body combustion chamber. The flue gas produced by incineration enters the second combustion chamber, and the unburned harmful substances in the flue gas are further destroyed in the second combustion chamber. In order to completely decompose the unburned embers and meet the emission requirements, the second combustion chamber is equipped with a burner to assist combustion, and is equipped with a unique secondary air supply device to ensure that the flue gas is in full contact with oxygen at high temperatures, and at the same time to ensure that the flue gas is in the second combustion chamber. The residence time of the combustion chamber is adjusted according to the oxygen content of the flue gas at the outlet of the second combustion chamber. The temperature in the second combustion chamber is controlled and the larger particles are removed by the dust collector, so that the incineration efficiency and destruction removal rate can reach more than 99%, so that it can achieve the effect of no odor, no odor and smoke, and reach the national emission standard. It enters the chimney and is discharged into the atmosphere, and the ashes produced after combustion are manually taken out, screened, transferred and buried.
