Cosmetics Ammonia Nitrogen Wastewater Treatment Biological Bacteria

The production of cosmetics will bring a large amount of cleaning wastewater, product manufacturing and other washing water. The high concentration of pollutants often leads to excessive ammonia nitrogen. There are many biodegradable substances, and it is difficult to meet the ammonia nitrogen emission standard after technological treatment.

conventional method of handling

1. Physical pretreatment, mainly including treatment facilities such as grids, adjustment tanks, sedimentation tanks, and air flotation tanks, which are used to adjust water volume and water quality; remove SS and suspended solids; and reduce part of the pollution load.

2. Using the metabolic function of microorganisms, the organic matter in the dissolved or colloidal state in the sewage is decomposed and oxidized into stable inorganic substances, so that the sewage can be purified. The commonly used methods are activated sludge method and biofilm method.

3. Air stripping method, the stripping process is to convert the ionic ammonium (NH4+) in the wastewater into molecular ammonia by adjusting the pH value, and then blown out by the incoming air or steam.

In order to better prevent the inspection due to excessive ammonia nitrogen in sewage, the sewage treatment must be efficient! The sewage after conventional treatment is generally between 100ppm-500ppm.

When the process reduction cannot meet the emission standard, adding ammonia nitrogen removal bacteria agent is an efficient method.
