High-concentration organic wastewater treatment and recycling device

Abstract

The invention discloses a high-concentration organic wastewater treatment and recycling device. The device includes a treatment tank, a feeding frame, a discharging tank, a spraying mechanism and an adsorption mechanism. The device is provided with the treatment tank which discharge organic wastewater from top to bottom; two storage trays are detachably mounted in the inner cavity wall of the treatment tank in a sliding manner; pulverized coal is placed in the two material storage trays in a filling mode. All high-concentration organic wastewater falling from the inner cavity of the treatmenttank can be ensured to be subjected to coagulation and adsorption of two layers of pulverized coal; a Fenton reagent is sprayed out from a spray head through a chemical pump to spray the chemical to the high-concentration wastewater between the two layers of storage trays, effects of catalytic oxidation and acidic coagulation on high-concentration wastewater are achieved, and the wastewater is finally discharged from the discharging tank. During coal powder replacement, the storage trays are directly drawn out, cover plates are opened, the coal powder is poured out, new coal powder is added, the treated coal powder is used for combustion, secondary pollution is avoided, and the coal powder is more economical than activated carbon as an adsorbent.

Description

technical field [0001] The invention relates to a recovery and reuse device, in particular to a high-concentration organic wastewater treatment recovery and reuse device, which belongs to the technical field of high-concentration organic wastewater treatment. Background technique [0002] High-concentration organic wastewater mainly has the following characteristics: first, high concentration of organic matter, second, complex composition, third, high chroma, peculiar smell, and fourth, strong acid and strong alkali. With strong acid or strong alkali, one is aerobic hazard, the other is sensory pollution, and the third is toxicity hazard. [0003] The actual practice of the traditional oxidation-adsorption method for the treatment of high-concentration organic wastewater is to discharge the wastewater into a coagulation adsorption pool mixed with coal powder, and then use Fenton reagent to catalyze oxidation and acid coagulation, and then use coal powder to coagulate and ads...
