Garbage Permeate Liquid Treatment Bacterial Agent

Garbage permeate liquid is a kind of highly polluted wastewater, which is the most difficult to treat, the most complex composition and the highest treatment cost in the field of polluted water. It contains special wastewater with high organic matter, high ammonia nitrogen and high salinity, with high pollutant content and biological toxicity.

1. Sewage treatment method

(1) blow-off method:

The stripping method is mainly to pass air into the water, and the gas and water are fully mixed and contacted, which destroys the equilibrium relationship of ammonia nitrogen in the water. The dissolved gas and volatile substances in the water reach the air through the gas-liquid interface to remove the dissolved gas in the water. and volatile substances. However, if the pH value needs to be adjusted, a large amount of alkali needs to be added, and air volume needs to be provided for aeration, resulting in high treatment costs, and the converted ammonia needs to be discharged into the atmosphere, causing new environmental pollution problems.

(2) Electrochemical oxidation method:

Under the action of the electric field, the ammonia nitrogen in the sewage is converted into N2, and then the ammonia nitrogen in the wastewater is removed by the oxidation of hypochlorous acid in the water. The electrochemical oxidation method has high removal efficiency and can also effectively remove refractory pollutants. The reaction is fast, but the power consumption is large and the operating cost is high.

(3) Biological denitrification technology:

The AO and UASB processes are usually used to remove the leachate according to the common law. However, because the leachate is mostly ammonia nitrogen, in order to better remove the ammonia nitrogen value, the SBR process will be used in the aerobic stage, which can reduce the ammonia nitrogen value to a very low level. Due to the influence of refractory substances in the leachate, the COD of the effluent will be very high.

(4) Garbage Permeate Liquid Treatment Bacterial Agent；

It can remove the ammonia nitrogen problem in sewage and leachate very well. It has high cost performance, the removal rate can reach more than 90%, the dosage is small, and there is no need to add other chemicals to mix and use, which effectively saves unnecessary It not only has the auxiliary functions of decolorization and COD reduction, but also does not need to adjust the pH value; and it responds quickly.
