Problems solved by technology

Due to the changes at different times in the production process, the salt concentration of the production wastewater is quite different, and the water quality is complicated, which cannot meet the needs of the normal operation of the subsequent biochemical system. Therefore, the existing food processing wastewater treatment method is used for brine The treatment effect of meat food processing wastewater is not good

Embodiment Construction

[0048] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and embodiments. The following examples are intended to illustrate the present invention, but not to limit the scope of the present invention.

[0049] like figure 1 As shown, the present invention provides a treatment device for food processing wastewater, comprising:

[0050] At least two drainage channels, each drainage channel is provided with a grease trap, and waste water with different salt concentrations generated in the process of food processing is discharged through different drainage channels;

[0051] Grille, the effluent of all grease traps is collected through the pipeline, and the non-dissolved oil stains are removed through the grille;

[0052] In the adjustment tank, the waste water flows into the adjustment tank after the non-dissolved oil pollution is removed through the grid, and the salt concentration of the wast...

Abstract

The invention relates to the technical field of sewage treatment, and discloses a treatment method and device for food processing wastewater. According to the technical scheme, the wastewater, with different salt concentration, produced in the food processing process is drained in a shunting mode, subjected to oil separating in advance, and then converged in an adjusting pool through a pipeline tobe uniformly mixed, thus salt salinity of the wastewater is neutralized, the salt concentration of the wastewater is within the set range, and it is ensured that the salt content of the wastewater can meet normal operation of subsequent biochemical devices. The treatment method adopts chemical air flotation treatment to preprocess the wastewater, and then adopts a hydrolytic acidification and aerobic method technology as the main technology for wastewater treatment, thus biochemical treatment of the food processing wastewater is achieved, organic matter in the food processing wastewater is removed, the treatment method has the advantages that management is simple, impact loading resistance is high, operation is stable, automatic control is easy to realize, and investment is also saved, and the treatment method is suitable for being used in medium and small-sized organic wastewater treatment stations.

Description

technical field [0001] The present invention is in the technical field of sewage treatment, in particular to a treatment method and treatment device for food processing wastewater. Background technique [0002] A lot of water is used in the processing of braised meat food, so a lot of waste is discharged as sewage. Due to the changes at different times in the production process, the salt concentration of the production wastewater is quite different, and the water quality is complex, which cannot meet the needs of the normal operation of the subsequent biochemical system. The treatment effect of meat processing wastewater is not good. SUMMARY OF THE INVENTION [0003] The invention provides a treatment method and a treatment device for food processing wastewater, which are used for treating high-salt food processing wastewater. [0004] In order to solve the above-mentioned technical problems, an embodiment of the present invention also provides a treatment device for foo...
