Abstract

The invention discloses a GAC / vermiculite filler-anaerobic fluidized bed process for treating leather disinfection wastewater, and belongs to the field of leather disinfection wastewater. A reactor body is provided with a separation zone, a precipitation zone and a reaction zone from top to bottom; the separation zone is provided with a water outlet, an exhaust pipe and a three-phase separator; the precipitation zone is positioned below the three-phase separator; the reaction zone is filled with an expanded vermiculite filler layer and a granular activated carbon (GAC) layer, the expanded vermiculite filler layer is located above the GAC layer, and anaerobic bacteria biofilms are attached to the expanded vermiculite and the GAC; a water inlet pump is positioned at the bottom of the reactorbody and is used for feeding leather disinfection wastewater into the reactor body through the water inlet pump; a reflux circulating pump is connected with the precipitation zone and the bottom of the reactor body and is used for keeping the fluidized state in the reactor body. Load is high, starting is fast, energy consumption is low, and impact load resistance is high; the device can operate under a high hydraulic load; the GAC / expanded vermiculite combined filler is high in biomass, high in volume load and high in organic matter decomposition efficiency.

Description

technical field [0001] The invention relates to the field of leather disinfection wastewater, in particular to a GAC / vermiculite filler-anaerobic fluidized bed process for treating leather disinfection wastewater. Background technique [0002] Leather disinfection wastewater is the wastewater produced after leather is disinfected with pyrethroids and quaternary ammonium salt disinfectants. A large amount of animal oil, collagen, and animal and plant fibers enter the wastewater along with the disinfection process. The concentrations of organic matter and organic matter are high, and they have certain toxicity to organisms, so it is difficult to deal with them. [0003] Pyrethroids are a class of important synthetic insecticides with high efficiency, broad spectrum, low toxicity and biodegradability. Due to the small dosage and low concentration, it is safer for humans and animals and has little pollution to the environment. Deltamethrin (molecular formula C 22 h 19 Br 2 ...
