Garlic wastewater treatment method and device

Abstract

The invention relates to a garlic wastewater treatment method and a device. The garlic wastewater treatment device comprises a wastewater regulating tank, an advanced oxidation reaction sedimentation tank, a multistage hypoxic and anaerobic reaction tank, an aerobiotic contact oxidation tank and a multilayer aerobiotic activity filtration tower, wherein the advanced oxidation reaction sedimentation tank comprises a mixing region and a sedimentation region; the multistage hypoxic and anaerobic reaction tank comprises a facultative section, a hypoxic section and an anaerobic section; an aeration controlling system is arranged at the middle lower part in the aerobiotic contact oxidation tank and comprises an aeration disc, an air blower and a dissolved oxygen measurement controlling device; and the multistage hypoxic and anaerobic reaction tank adopts multistage arrangement, particle sizes of a filter material are gradually decreased from top to bottom, an air inlet, a water collection groove and a water outlet pipe are arranged at the bottom of the filtration tower, and disinfection equipment is installed at the upper part of the water collection groove and is connected with a chloride dioxide generator. The garlic wastewater treatment device has a simple structure, is lower in manufacturing cost, is suitable for sewage treatment of larger volume and has very good treating effect to garlic wastewater.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a garlic wastewater treatment method and device. Background technique [0002] The main components of garlic include sugars, amino acids, lipids, peptides, sulfur-containing compounds, vitamins, and trace elements. In recent years, the garlic processing industry has formed a large scale. Garlic dehydration production and processing generally include several processes such as selection, cleaning, slicing, rinsing, dehydration, water balance, sorting, packaging, and finished products. A lot of waste water. Garlic wastewater is high-concentration wastewater and has a strong antibacterial effect. The thioether in allicin can oxidize enzymes containing sulfhydryl groups, inhibit cell division, and destroy the normal metabolism of microorganisms. Therefore, traditional physicochemical and biochemical methods are used for wastewater treatment. The processing effect is poor. ...
