Embodiment 2

[0071] This example discloses a phenolic pollutant removal system based on a moving bed biofilm reactor. Based on Example 1, we set the hydraulic residence time of the entire reactor to 24h in Example 2.

[0072] 1. Wastewater treatment parameters

[0073] The wastewater is treated with simulated wastewater prepared in the laboratory. The main water quality indicators: COD 1500mg / L, NH 4 + -N90mg / L, phenol concentration 600mg / L, p-chlorophenol concentration 30mg / L.

[0074] 2. Wastewater treatment stage

[0075] The reactor was operated in sequential batch mode, and the hydraulic retention time was set to 24h. The other conditions are consistent with Example 1.

[0076] 3. The effect of reactor operation

[0077] After testing, the change of hydraulic retention time significantly affected the phenol removal performance of the combined system. Monitor the concentration of phenol in the effluent of the reactor (12h, 24h) and the concentration of p-chlorophenol in the effluent (6h, 12h) b...

Abstract

The invention provides a phenol pollutant removal system and method based on a moving bed biofilm reactor. The phenol pollutant removal system based on the moving bed biofilm reactor comprises a reactor, a water inlet pump, an aeration pump and an aeration head; a water inlet at the upper end of the reactor communicates with the water inlet pump; the reactor is internally provided with biologicalmembrane filler; the bottom of the reactor is provided with a biological manganese oxide; the aeration head is arranged in the reactor and above the biological manganese oxide, wherein the aeration head communicates with the aeration pump arranged above the reactor through a pipeline; and a water outlet is formed in the side wall, above the biological manganese oxide, of the reactor. According tothe phenol pollutant removal system based on the moving bed biofilm reactor, the biological manganese oxide can be generated in situ, and combined catalysis of microorganisms / the biological manganeseoxide on phenolic pollutants is realized.

Description

Technical field [0001] The invention relates to water treatment technology, in particular to a phenolic pollutant removal system and method based on a moving bed biofilm reactor. Background technique [0002] In recent years, reports and researches on phenolic pollutants in industrial wastewater have become more and more extensive. How to effectively remove phenolic pollutants contained in industrial wastewater has become a hot research topic at home and abroad. Phenolic pollutants, as a class of pollutants that are highly toxic to humans and the environment, are often by-products produced in industrial production processes, and cover many areas, including drugs, personal care products, steroid hormones, chemical raw materials, and pesticides. Insect agents and so on. With the rapid development of petrochemical, oil refining, plastics, pharmaceutical and other industries, the types and quantities of phenol-containing wastewater discharged are also increasing, posing a huge threa...
