A kind of garlic wastewater advanced treatment system

Abstract

The invention relates to a system for the advanced treatment of garlic wastewater, which comprises a wastewater regulating pool, an enhanced air flotation pool, an ozone oxidation-precipitation tank, a packed anoxic / anaerobic reaction tank, a baffled biological aerated filter and an oxidation pond, wherein the enhanced air flotation pool is sequentially provided with a mud-sand area, a mixing area and a separating area from top to bottom, the ozone oxidation-precipitation tank comprises an aerated mixing area and a precipitation area, the packed anoxic / anaerobic reaction tank comprises a facultative section, an anoxic section and an anaerobic area which are partitioned by using baffle plates, and the baffled biological aerated filter comprises a lower flow area, an upper flow area and a sludge area. Wastewater enters the enhanced air flotation pool via the regulating pool so that scum can be removed; then, the wastewater enters the ozone oxidation-precipitation tank, and pollutants are subjected to oxidative decomposition; then the wastewater enters the packed anoxic / anaerobic reaction tank for anoxic and anaerobic reactions; after being reacted and filtered in the baffled biological aerated filter, the wastewater enters the oxidation pond, and water treated by the oxidation pond is reused.

Description

Technical field [0001] The invention relates to the technical field of wastewater treatment, in particular to a garlic wastewater advanced treatment system. Background technique [0002] my country's garlic production is very high, ranking first in the world, accounting for about 1 / 4 of the world's total output. Most enterprises mainly focus on the processing and production of garlic slices. The production and processing of garlic garlic chips generally includes several processes such as selection, cleaning, slicing, rinsing, dehydration, moisture balance, sorting, packaging, finished products, etc., resulting in garlic wastewater. The wastewater contains more floating matter and has a high COD concentration. Contains allicin with strong bacteriostasis and bactericidal effect, making the wastewater become high-concentration and refractory wastewater.
