Combined bio-trickling filter linkage organic waste gas treatment equipment

Abstract

The invention discloses combined bio-trickling filter linkage organic waste gas treatment equipment, which relates to an organic waste gas and waste water treatment device in environmental engineering. The invention adopts two sets of independent bio-trickling filters, increases a sewage inlet system, increases a back flushing gas inlet system, simultaneously has the effect of an aeration system, increases serial connection gas pipes 9 and 9', increases three-way valves 21, 21', 44 and 44', increases four-way valves 30 and 30', increases relevant valves, and controls the gas inlet and the liquid inlet, so the invention can operate in various modes such as parallel connection operation, serial connection operation, waste water and waste gas simultaneous treatment operation, waste water single treatment operation and the like. Four active carbon fiber cloth filling material processing units are filled and arranged in the bio-trickling filter and are in overlapped arrangement, the filling materials are multilayer cylindrical carbon fiber cloth and are in concentric cylindrical distribution, the diameter of the cylindrical active carbon fiber cloth filling material layer is gradually reduced from outside to inside, the gaps of each layer of filling materials are gradually reduced, the filling materials in the center are compact, the filling materials at the periphery are relatively sparse, and the upper ends of the filling materials are fixed on the same plane.

Description

technical field [0001] The invention relates to a treatment device for organic waste gas in environmental engineering, in particular to a combined biological trickling filter tower treatment device for organic waste gas, which can also be applied in the field of waste water treatment. Background technique [0002] Volatile organic compounds usually refer to organic compounds with a boiling point of 50-260°C and a saturated vapor pressure of more than 133.32Pa at room temperature, mainly classified into hydrocarbons, halogenated hydrocarbons, nitrogen hydrocarbons, oxygen-containing hydrocarbons and polycyclic aromatic hydrocarbons with low boiling points Wait. Volatile organic compounds are toxic, irritating and carcinogenic, and will cause great harm to human health. Halogenated hydrocarbons can also interact with NO in the atmosphere 2 The reaction produces O 3 , have a great impact on the ecological environment. [0003] The traditional methods of dealing with volatil...

AI Technical Summary

Problems solved by technology

The chemical method is to add chemical substances to inhibit the growth of microorganisms, and it is easy to produce new pollutants, which will affect the activity of microorganisms and reduce the treatment efficiency

Physical and mechanical methods to control the growth of microorganisms often use flushing or backwashing, which requires a large reaction bed, produces a large amount of high-BOD wastewater, cannot operate continuously, and requires a certain period of time to restore activity after treatment.
