Abstract

The utility model discloses a garlic processing wastewater treatment device, which is characterized that a grating, a hydrolyzing acidifying tank, a micro-electrolyzing catalyzing oxidizing tank, a neutralizing sedimentation tank and a sequencing batch reactor (SBR) are arranged sequentially on the wastewater treatment device, wastewater flows through the device sequentially, an ozone reactor is further arranged on the wastewater treatment device, an ozone outlet is connected into the micro- electrolyzing catalyzing oxidizing tank through a pipeline, and the hydrolyzing acidifying tank and the bottom of the SBR are respectively connected to a sludge concentration tank through a pipeline. By the aid of micro-electrolysis catalysis and oxidization with the help of ozone, allicin is removed effectively, and then the garlic wastewater is treated through the SBR biochemnical process, and effluent can reach the second standard of Integrated Wastewater Discharge Standard (GB8978-1996).

Description

Garlic processing waste water treatment facility

Technical field

The utility model relates to the garlic processing waste water and administers technology, belongs to technical field of sewage treatment, specifically is a kind of garlic processing waste water treatment facility.

Background technology

Garlic is not only a kind of vegetables commonly used or food flavouring, and has multiple physiological function.There is the prospect of develop and useining widely in fields such as, the crop growth fresh-keeping at medicine, food, beauty treatment, breed, agricultural and animal products and the prevention and control of plant diseases, pest control.

Plurality of processes such as the garlic process for processing generally comprises and selects, clears up, section, rinsing, dehydration (oven dry), equilibrium water content, sorting, packing, finished product, in wherein cleaning, rinsing and the dehydration, can produce a large amount of waste water, the difficult point that the garlic processing waste water is administered is the garlicin that wherein contains.

The molecular formula of garlicin is C ₆H ₁₀S ₃, chemical name is a diallyl trisulfide, and relative molecular mass is 178, and total content 〉=95% has strong impulse flavor and distinctive sharp flavor, is insoluble in water, is oily liquids, can mix with ethanol, ether and benzene etc.Disulfide in the garlicin and trithioether can permeate through cell membranes enter in the tenuigenin, and the oxydasis that will contain sulfydryl is a cystine linkage, thereby suppress cell fission, the eubolism of destroy microorganisms.Therefore, must effectively remove garlicin, be difficult to prove effective otherwise adopt traditional biochemical process to handle the garlic processing waste water.

The utility model content

The purpose of this utility model is to provide a kind of stabilizing effective garlic processing waste water treatment facility.

For reaching this purpose, the utility model adopts following technical measures:

Garlic processing waste water treatment facility is characterized in that being disposed with grid, hydrolysis acidification pool, little catalytic and oxidative electrolysis technology pond, neutralization precipitation pond, sbr reactor device, and the sewage aforesaid device of flowing through is successively handled; Be provided with ozonizer, its ozone outlet is attached in little catalytic and oxidative electrolysis technology pond by pipeline, and hydrolysis acidification pool and sbr reactor device bottom have sludge pipe to be attached to sludge thickener respectively.

Garlic processing waste water treating processes is as follows:

1, waste water by grid, is held back bigger suspended substance earlier, guarantees the normal operation of subsequent disposal facility.

2, waste water is gone into the hydrolysis acidification pool by grid is laggard, makes the non-solubility organism under the effect of microbial hydrolase, and chain rupture by larger molecular organics and bio-catalytical oxidation reaction such as water-soluble are converted into solvability monomer or dimer; Make dissolved organic matter be converted into voltaile fatty acid (as acetate, propionic acid and butyric acid etc.).By acidication the larger molecular organics of difficult degradation is converted into and is easy to biodegradable small-molecule substance, improve biodegradable property of wastewater and biodegradation rate.

3, the hydrolysis acidification pool water outlet enters little electrolytic catalysis reaction tank, and the ozone that ozonizer is produced imports little electrolytic catalysis reaction tank, under acidic conditions, sewage is carried out aeration, the polymer long-chain compound is become micromolecular compound, improve the biodegradability of sewage.

4, the water outlet of little electrolytic catalysis reaction tank enters the neutralization precipitation pond, by adding Ca (OH) ₂Regulate pH to neutral.

5, the water outlet of neutralization precipitation pond enters the sbr reactor device, by biochemical reaction, removes principal pollutant such as COD, ammonia nitrogen significantly.

6, the mud of hydrolysis acidification pool, neutralization precipitation pond and sbr reactor device enters sludge thickener, and outward transport is disposed after the concentrated mummification.

The utility model adopts the auxiliary little catalytic and oxidative electrolysis technology of ozone, effectively remove garlicin after, by the SBR biochemical process garlic waste water is handled again, water outlet reaches " integrated wastewater discharge standard " secondary standard (GB8978-1996).

Embodiment

This example is at the 80m of garlic processing enterprise ³/ d scale waste water, adopt the utility model to administer:

1, thick, the fine fack of 2m * 2m * 2m is set;

2,10m * 8m * 4.5m hydrolysis acidification pool is set;

3,2 little electrolytic catalysis reaction tanks of 1.5m * 1.5m * 2m are set, ozonizer 300g/h, ozone concn are 16～22mg/L;

4, the sbr reactor device of 6.0m * 2.5m * 3.0m is set.

Set gradually grid, hydrolysis acidification pool, little catalytic and oxidative electrolysis technology pond, neutralization precipitation pond, sbr reactor device, the sewage aforesaid device of flowing through is successively handled; Ozonizer, its ozone outlet is attached to the supply of the waste water in pond ozone in little catalytic and oxidative electrolysis technology pond by pipeline, and hydrolysis acidification pool and sbr reactor device bottom have sludge pipe to be attached to sludge thickener respectively.

After the engineering stability operation, principal pollutant Inlet and outlet water concentration sees Table, and satisfies " integrated wastewater discharge standard " secondary standard (GB8978-1996).
