Pretreatment of Breeding and Slaughtering Wastewater Dissolved Air Floatation Precipitator

Dissolved air floating machine details:

oneThe dissolved air floating machine is the domestic advanced dissolved air floating machine, is the use of high efficiency dissolved air pump will water, gas mixture pressure dissolution to form dissolved air water, and then decompression release micro bubble formation and suspended particles high efficiency adsorption and rise, so as to achieve the purpose of solid liquid separation.

twoFunctional features:

1.Solution air pump suction suction, pump pressure mixing, high gas-liquid dissolution efficiency, fine bubble ≤30um.

2.Dissolved air pump can replace the circulation pump, air compressor, dissolved air tank, jet and release head of the complex system.

3.Low pressure operation, gas dissolving efficiency up to 99%, release rate up to 99%.

4.The efficient adsorption of microbubbles and suspended particles improves the removal effect of SS.

5.The dissolution efficiency of dissolved gas and water is 80-100%, which is 3 times higher than that of conventional dissolved gas and air flotation.

6.Pressure - capacity curve flat, easy to achieve automatic control, easy to operate and maintain, low noise.

3.Equipment construction:

1. The air flotation system integrates water inlet, flocculation, separation, water collection and water outlet. Similar to the traditional air flotation equipment, it is equipped with a stable flow chamber and a dissolved gas release chamber to make the treatment performance more stable and the effect more superior.

2. Stable room: through the folded plate of raw water, flow rate is very high, if direct contact with the dissolved air water, will dissipate the tiny bubbles and influence flocculant bubbles from block effect, thus reducing gas float processing efficiency, if increased the steady flow chamber, the turbulent kinetic energy consumption, raw water into the dissolved air water release chamber at a constant speed, so as to guarantee the removal efficiency.

3. Dissolved gas release chamber: dissolved gas release chamber and separation chamber are in a tank.Separated in the middle, the dissolved air water and the flocculated raw water adhere here and slowly rise into the air float separation chamber, ensuring the contact space and time between the flocculation and the tiny bubbles, and making the release rate of dissolved air water reach 80-100%

Four.Dissolved gas system:

For air flotation equipment, dissolved gas system is the "heart" of air flotation equipment, is also the main parts of air flotation equipment, in this phase, gas and water in the inlet of the pump suction, together with the impeller shear pressurized dissolved air water mixture, gas-liquid two-phase mixture and fully saturated, dissolved air system of a complete set of the largest air content reaches 10%, and the solubility of a gas is 100%, when the gas dispersion of micro air bubble distribution uniformity, the average bubble diameter is less than 30 um.The dissolved gas system is an improvement and technological innovation to the traditional air flotation, which improves the air flotation separation efficiency and greatly reduces the production and operation costs of the equipment.

Five.Scraping the slag machine:

The operation mode and speed of slag scraper have a direct influence on the water quality and sludge solids.The system adopts rotary slag scraper, which can scrape the scum continuously and uniformly into the scum tank, and reduce the scum collision.In addition, the scraper with adjustable height can better adapt to various operating conditions and reduce the moisture content of sludge.

Vi. Control system:

Advanced electrical components are used in the control system to ensure the long-term effective operation of the equipment.

Seven.Scope of application:
