Embodiment 1

[0052] A soy sauce wastewater treatment system, the treatment process is fine grid + regulating pool + ABR reactor + SBR reactor + mechanical coagulation + high-efficiency sedimentation + disc filtration + sodium hypochlorite disinfection, in which calcium chloride is used as the coagulant, and the dosage It is 1.1g / L. See the table below for influent and effluent water quality.

[0053] Table 1 List of influent and effluent water quality

[0054]

[0055]

[0056] It can be seen from Table 1 that the effluent BOD and ammonia nitrogen can reach the first-class A standard, but the COD and chromaticity can only meet the second-class standard effluent.

[0057] Implementation process: the equipment of the present invention is directly installed at the end of the above-mentioned process system, before the total discharge port, the equipment shell adopts steel-lined plastic, cube; the design flow velocity of the water inlet is 1.05m / s; the design flow velocity of the diversi...

Embodiment 2

[0060] A soy sauce wastewater treatment system, the treatment process is fine grid + regulating pool + air flotation reactor + UASB reactor + SBR reactor + mechanical coagulation + inclined plate sedimentation + active sand filtration + ozone disinfection, in which the coagulant is PAC , the dosage is 260g / L. See the table below for influent and effluent water quality.

[0061] Table 2 List of influent and effluent water quality

[0062]

[0063]

[0064] It can be seen from the process and Table 2 that although the effluent has reached the first-class B standard, the process chain is long and the dosage is large, especially the operation of the anaerobic reactor requires professional control, which increases economic and human pressure on soy sauce enterprises.

[0065] Implementation process: stop using the UASB reactor in the original system, add the equipment of the present invention before the SBR; the design flow velocity of the water inlet is 1.0m / s; the design f...

Abstract

The invention belongs to the field of sewage treatment equipment manufacturing, and concretely relates to modified filler reactor for decolorizing soy sauce wastewater. Aiming at solving the problemsthat soy sauce wastewater chroma composition substances generated in the production process of soy sauce enterprises are extremely complex and difficult to remove, and material research and development and equipment design are carried out. The modified filler reactor comprises an equipment shell 1, a water inlet 2, a flow guide channel 3, a water inlet distributor 4, a modified filler 5, a modified filler supporting layer 6, a water outlet channel 7, a water outlet 8, an anode 9, a cathode 10, an electric wire 11 and a direct-current external power supply 12, wherein the modified filler 5 is prepared from a modified carbon powder solution, a modified aniline material and modified carbon fibers. The modified filler reactor can significantly reduce the chromaticity of the soy sauce wastewater, and has the advantages of good treatment effect, low operation cost and the like.

Description

technical field [0001] The invention belongs to the field of sewage treatment equipment manufacturing, and specifically relates to a soy sauce wastewater decolorization modified packing reactor. Aiming at the problem that the chromaticity constituent substances of soy sauce wastewater produced in the production process of soy sauce enterprises are extremely complex and difficult to remove, material research and development and equipment are carried out. design. Background technique [0002] As one of the most commonly used condiments in people's daily life, soy sauce meets people's dietary needs, but its production process also brings serious environmental pollution problems. Studies have shown that the production of 1 ton of soy sauce needs to consume 7 to 10 tons of water, which will bring about 6 to 9 tons of wastewater. The main components in wastewater include food residues, fermentation process products, trace detergents, disinfectants, a large amount of salt, various...
