Problems solved by technology

[0008] Aiming at the technical problems existing in the existing treatment of alkaloid-containing industrial waste alkaline water, the present invention proposes a treatment system and treatment method for alkaloid-containing waste alkaline water. The process is simple and the practicability is high. High COD alkaloid wastewater can easily treat a large amount of ordinary wastewater at the same time, which greatly reduces the cost of high COD wastewater treatment, and at the same time solves the problem that alkaloid wastewater is difficult to be treated by biological oxidation, and realizes the comprehensive treatment of waste alkaline water

Embodiment 2

[0060] Taking specific alkaloid waste alkaline water as an example, the treatment system of the present invention is used to treat alkaloid waste alkaline water.

[0061] Specifically, the alkaloid waste alkaline water is the matrine industrial waste alkaline water, the density of the alkaloid industrial waste alkaline water is 1.25, the pH=12, and the COD is 500000mg / L; the processing steps are as follows:

[0062] 1) neutralize the alkaloid waste alkaline water through the wastewater pretreatment system, heat and distill under reduced pressure to obtain distillate and residual liquid;

[0063] 1.1) Inject 1000kg of matrine industrial waste alkaline water into the reactor 1 through the feed pump P2, and inject about 60kg of industrial waste concentrated sulfuric acid through the adjustment pump P1, stir the reaction, control the pH to 7, and complete the neutralization;

[0064] Then add about 25 kg of defoamer to reactor 1 through defoamer storage tank 2, stir evenly, and wa...

Abstract

The invention belongs to the technical field of industrial wastewater treatment, and relates to an alkaloid waste alkaline water treatment system and method. The treatment system comprises a wastewater pretreatment system, and an incineration tower and a biological oxidation system which are respectively communicated with the wastewater pretreatment system, wherein the wastewater pretreatment system comprises a reaction kettle, a condenser and a distillate storage tank which are communicated in sequence, the reaction kettle is communicated with the incineration tower, the distillate storage tank is communicated with the biological oxidation system, the wastewater pretreatment system further comprises a defoaming agent storage tank and a vacuum pump, the defoaming agent storage tank is communicated with the reaction kettle, and the vacuum pump is communicated with the distillate storage tank. According to the invention, the treatment method is simple in process and high in practicability, a small amount of high-COD alkaloid wastewater is reduced while a large amount of common wastewater can be simply treated, the technological treatment cost of the high-COD wastewater is reduced toa great extent, the problem that alkaloid wastewater is difficult to biologically oxidize is solved, and comprehensive treatment of waste alkaline water is achieved.

Description

technical field [0001] The invention belongs to the technical field of industrial wastewater treatment, and relates to an alkaloid waste alkali water treatment system and a treatment method. Background technique [0002] Alkaloid waste alkaline water is the waste water after the treatment of alkaloid-containing plants through alkali extraction, concentration, extraction and other processes. The specific gravity is about 1.2, the color is dark brown, and there is a peculiar smell. The COD is about 300,000-500,000 mg / L. At present, there are 5000-6000 kinds of alkaloids isolated from plants. Alkaloids have various modes of action on insects, such as poisoning, repelling, antifeedant, inhibiting growth and development, etc., and have strong antibacterial and bactericidal effects. Therefore, these alkaloid waste alkaline waters are treated so that they can be used in other aspects, especially in agriculture, so as to make the best use of them. [0003] At present, the main meth...
