Polycyclic aromatic hydrocarbons refer to 2-4 ring aromatic hydrocarbons.
The bioavailability of the hydrophobic organic matter is improved by forming the cloud point system, the application of the cloud point system in the degradation of the hydrophobic organic pollutant is realized, and the environmental pollution treatment is facilitated. The cloud point system extracts hydrophobic organic matters which are difficult to dissolve in water into the coacervate phase to form dissolved organic matters, and because the concentration of the organic matters in the coacervate phase is higher than that of the organic matters in the water phase, the organic matters are diffused and transferred from the coacervate phase to the water phase until the coacervate phase is balanced according to a two-phase balance principle. On one hand, the concentration of the organic matter substrate in the water environment where the microorganism is positioned is obviously increased, and the biodegradation efficiency of the microorganism is obviously improved; on the other hand, as the organic matters in the water environment are degraded by microorganisms, the organic matters in the cloud point system coacervate phase are further diffused and transferred to the water phase, and the balance of the substrate in the two phases is kept, so that the continuous degradation of the organic matters is ensured. The key to this process is that the cloud point system does not affect the microbial degradation activity while changing the bioavailability of hydrophobic organics.
