Working Principle

ZSF series dissolved air floatation sewage treatment machine is of steel structure. Its working principle is: the air is pumped into the pressure dissolved air tank and forcibly dissolved in water under the pressure of 0.m5pa. In the case of sudden release, the air dissolved in the water is precipitated to form a large number of dense microbubbles. In the process of slow rise, the suspended solids are adsorbed to reduce the density of suspended solids and float upward, The purpose of removing SS and CODcr is achieved. The product is suitable for sewage treatment of petroleum, chemical industry, papermaking, leather, printing and dyeing, food, starch and so on.

Application

1. The total content of heavy metal ions such as zinc, copper and lead in waste electroplating water is less than 50ppm, and the removal rate can be more than 70%.
2. The chroma removal rate of printing waste dyeing water is about 90%, COD removal rate is about 60-7%, BOD removal rate is about 50%.
3. The COD removal rate of slaughtering and tanning wastewater is about 70%, and the suspended solids removal rate is about 90%.
4. The oil and grease of waste oil and water can be reduced to less than 10mg / L, and the wastewater can reach the degree of clarification.
5. For industrial and chemical wastewater, pigment and paint, the COD removal rate is 74%, and the chroma removal rate is about 93%.
6. The fiber recovery rate of white paper making water can reach about 95%, the COD removal rate is about 867%, and the clean water can be completely reused.
7. The turbidity of the bath water in the large bathing pool can be stabilized below 10 degrees, and the bacteria in the water can be greatly reduced.
8. The turbidity of raw drinking water and industrial water can be purified below 5 degrees. At the same time, it has a good effect on reducing chroma oxygen consumption.

Technique Parameter

Air flotation machine is a water treatment equipment that generates a large number of micro bubbles in the water by the dissolved air system, causing air to adhere to suspended particles in the form of highly dispersed micro bubbles, resulting in a density less than water. It uses the principle of buoyancy to float on the water surface, thus achieving solid-liquid separation. Air flotation machines are divided into super efficient shallow air flotation machines, concave air flotation machines, and horizontal flow air flotation machines. It has applications in water supply, industrial wastewater, and urban sewage treatment. The advantage of an air flotation machine lies in its solid-liquid separation equipment, which has the characteristics of low investment, minimal floor space, high degree of automation, and convenient operation and management.
