Zero discharge system of garlic processing wastewater

Abstract

The invention provides a zero discharge system of garlic processing wastewater. The zero discharge system comprises an adjusting tank, a metal self-cleaning filter, a high-capacity ultrafiltration membrane system, a first middle water tank, a primary MS-R membrane system, a second middle water tank, a secondary MS-R membrane system, a concentrate tank and a multi-effect evaporator, wherein the adjusting tank, the metal self-cleaning filter, the high-capacity ultrafiltration membrane system, the first middle water tank and the primary MS-R membrane system are sequentially connected in a communicated way; a wastewater pipe of the metal self-cleaning filter is communicated with the adjusting tank; a concentrated water pipe of the primary MS-R membrane system, the concentrate tank and the multi-effect evaporator are sequentially connected in a communicated way; a produced water pipe of the primary MS-R membrane system, the second middle water tank and the secondary MS-R membrane system aresequentially connected in a communicated way. The zero discharge system solves the problems of secondary pollution, resource waste and the like in the process of garlic producing wastewater treatment, achieves zero organic wastewater discharge of the garlic processing wastewater and efficient recycling of active components, and achieves the recycling rate of 98% or above.

Description

technical field [0001] The invention relates to the technical field of garlic processing, in particular to a zero discharge system for garlic processing wastewater. Background technique [0002] Garlic is an important agricultural and sideline product. Studies have shown that in addition to its anti-inflammatory and anti-aging effects, its rich allicin can also act on the initiation stage of tumors, interfere with the activation of carcinogens, and enhance the immune function of the system. Based on the excellent efficacy of garlic, in recent years, garlic product deep-processing enterprises have continued to expand, and at the same time, a large amount of waste water from garlic processing and production has also been generated. [0003] The traditional garlic wastewater treatment processes are mainly: biochemical method and Fenton oxidation method, using activated sludge to degrade the organic matter in garlic wastewater, and finally meet the discharge standard and dischar...
