Henan Food Sewage Treatment Project Needs the Right Medicine

Henan food wastewater treatment project has a positive and positive effect on environmental protection, so it is important to do this work well. To do well, you need to understand the goals that this work will cure.

The oils in food waste water are divided into suspended state, emulsified state and dissolved state. The first is the highest in sewage, accounting for 80% to 90% of the total oil content, and the particles are larger; the emulsified state accounts for about 10% to 15% of the total oil content, the oil bead particles are small, and the diameter is generally between Between 0.05 and 25 fim, it is not easy to be removed by floating; this part of the oil in the dissolved state only accounts for 0.2% to 0.5% of the total oil content. Because the content is small, the sewage can meet the discharge requirements as long as the first two oils are removed.

For suspended oils with relatively large oil bead sizes, they are generally separated by oil traps; for emulsified oils, they are separated by flotation. The commonly used oil traps are almost flow type, vertical flow type and inclined plate type. In China, advection type oil traps are mostly used, and their structure is similar to that of advection type sedimentation tanks. In actual operation, they are mainly used for oil isolation, but they also have a certain sedimentation effect.

The ordinary advection oil separation tank is similar to the sedimentation tank. Food sewage enters from one end of the tank and flows out from the other end. Because the horizontal flow velocity in the tank is very small, the light oil droplets in the water float up under the buoyancy and accumulate on its surface. The oil slick is collected through oil collecting pipes and oil scrapers located on the pool surface. However, in order to improve the processing capacity of the unit pool, the oil trap also adopts a sloping plate type, and the material is a polyester fiberglass corrugated plate. The treatment efficiency of the inclined plate type oil trap is generally 2 to 4 times that of the advection type.
