The main pollution indicators in beer wastewater are CODcr, BOD5, SS, etc., and the BOD5/CODCB of wastewater is 0.5 ~ 0.6. The biochemical property is good, and it is easy to adopt biochemical treatment.

The main craft. Finally, the ozone system is combined to deal with COD sterilization.

Brewery wastewater treatment process:

Firstly, the sewage is pretreated by intercepting the grid, the purpose is to initially reduce the content of inorganic particulate matter, and improve the identity and biodegradability of sewage;

Then, the lifting pump is quantitatively lifted to the regulating tank to regulate the water quality and quantity. The regulated sewage is passed through the anaerobic, anoxic and aerobic [**]2/0 biological contact oxidation method, which is used

The role of biofilm makes organic pollutants firstly converted into ammonia nitrogen, and at the same time removes both organic matter and ammonia nitrogen through aerobic nitrification and anoxic denitrification.

Ozone catalyst (Breweries Ozone Water Treatment system)

Using aluminum base as the carrier, using precious metal materials, and using different ozone catalysts for different sewage water quality, can improve the COD removal rate of sewage.

Breweries Ozone Water Treatment system Catalyst [**]pplications:

Ozone oxidation for general industrial wastewater, pharmaceutical wastewater, petrochemical wastewater, oily wastewater, high-salt wastewater, ammonia nitrogen removal wastewater, pesticide wastewater, benzene wastewater, steel wastewater, electroplating wastewater, and surfactant wastewater removal.

Breweries Ozone Water Treatment system Ozone Dissolving Device

It is a key equipment for ozone utilization and directly affects operating costs.

Breweries Ozone Water Treatment system Ozone dosing in five ways

1. Waterfall gas pool (tower): Titanium explosion gas disc, long handle filter head, height 6 meters required

2. Ejector: air-water mixing (flow type design, dissolved air type design)

3. Secondary ejector: the water-air mixture is mixed with water

4. Dissolved air pump: (Small-sized alternative to high water tanks, large-scale dissolved air pumps are currently not available, only 50 tons/hour or less)

For the same power consumption, there is a big gap between manufacturers. 40%-85% efficiency ranges.

Combined with high-concentration Breweries Ozone Water Treatment system and ozone catalyst, the size of the ozone reaction pool will be greatly reduced.

5. The ozone dissolving device is currently mainly used in large-scale municipal sewage and industrial sewage, which can increase the ozone mixing efficiency to 90-95%.
