Problems solved by technology

[0003] The traditional integrated treatment method of Hu sheep slaughter, domestic sewage and cooked food processing wastewater is relatively complicated. The three kinds of sewage and solid substances are separated and separated. Solid impurities are generally processed by aging. The traditional treatment method and steps are large meat, uneven aging, and cannot fully mature the solid matter. There will be some clinker with waste in the mixture, as well as silt and cooked meat. Mixed together, it is difficult to separate and degrade later

Embodiment 1

[0047] An integrated treatment method for Hu sheep slaughter, domestic sewage and cooked food processing wastewater, comprising:

[0048] (1) Concentrated mixing, adding the sewage, domestic sewage and cooked food processing wastewater from the Huyang slaughtering workshop to the pre-adjustment tank, adding lye to adjust the PH to homogenize the water quality, and continuously stirring during the adding process to accelerate the dissolution of lye ,Improve efficiency;

[0049] (2) Solid-liquid separation, the pre-adjusted mixture is added to the integrated treatment device, and the liquid, solid and water-soluble suspended matter are separated and collected;

[0050] (3) Concentration, drying, and dehydration. The solid sediment and minced meat separated from solid and liquid are sequentially added to the sludge adjustment tank and dehydrator for dehydration and drying, and then transported, and the solids are dried and discharged to collect the liquid;

[0051] (4) Separatio...

Embodiment 2

[0057] see Figure 1-4 , 7, on the basis of embodiment 1, the integrated device includes a box body 1, the lower end of the box body 1 is provided with a hopper 14, and the middle part of the box body 1 is fixedly provided with a straight plate 10. The middle part of the straight plate 10 is symmetrically provided with a second drop opening 43;

[0058] Suspension removal device, which is arranged on the upper end of the straight plate 10, the suspension removal device includes a settling box 36, above the settling box 36 are provided with two conveying rollers 34 that are rotatably connected to the inner wall of the box body 1, and the conveying rollers 34 pass through Belt 29 transmission connection, the upper end of the transfer belt 29 is equipped with a number of collecting claws 31 through the fixed plate 32, a conveyor belt 35 is installed obliquely on one side of the transfer belt 29, and a first drop opening 42 is symmetrically opened at the lower end of the settling ...

Embodiment 3

[0074] see Figure 5 As shown, on the basis of Embodiment 1, according to the present invention, the switch device includes an arc groove 13 provided at the lower end of the separation cylinder 11, and the symmetrical arc groove wall of the arc groove 13 is provided with a rolling groove 15 and a moving groove 18 respectively. , the rolling groove 15 is provided with a ball 16, the moving groove 18 is slidably provided with an arc plate 19, the arc plate 19 and the ball 16 are fixedly connected by a pull cord 17, and the arc plate 19 is connected to the wall of the moving groove 18 A tension spring 20 is fixedly provided.

[0075] Specifically, the separation cylinder 11 rotates at a high speed, the balls 16 perform centrifugal motion in the rolling groove 15, and the moving plate 19 is pulled by the stay rope 17 to move in the movement groove 18, and the arc groove 13 is blocked. When the separation cylinder 11 stops rotating, The arc groove 13 leaks out and communicates wit...

Abstract

The invention belongs to the technical field of wastewater treatment, and particularly relates to an integrated treatment device and method for Hu sheep slaughtering, domestic sewage and cooked food processing wastewater, and the method comprises the steps: performing centralized mixing, performing solid-liquid separation, performing concentration and drying, performing dehydration, performing oil stain separation, operforming rganic matter degradation and disinfection, performing processing wastewater mixing, and adding the wastewater into a pre-adjusting tank; adding a pre-regulated mixture into an integrated treatment device, separating liquid from solid and suspended matters, dehydrating, drying and transferring solid silt and minced meat obtained by solid-liquid separation, adding the collected liquid into an oil separation sediment tank, collecting sediment, adding wastewater into a flocculation air floatation tank, adding the collected clear water into a regulating tank, an anaerobic tank, a hydrolysis tank, an aerobic tank, an anaerobic tank, a hydrolysis tank and an aerobic tank in sequence. According to the invention, three sewage mixtures are added into the integrated treatment device to be subjected to solid-liquid separation together, separation is thorough, the whole process steps are shortened, the working efficiency is improved, clear water is added into the anaerobic tank and the aerobic tank for multiple times, and organic matter decomposition is thorough.

Description

technical field [0001] The invention belongs to the technical field of wastewater treatment, and in particular relates to an integrated treatment device and method for Hu sheep slaughter, domestic sewage and cooked food processing wastewater. Background technique [0002] Hu sheep slaughtering and cooked food processing wastewater generally comes from livestock and poultry slaughtering workshops, cooked food processing workshops and domestic sewage. Slaughtering workshop wastewater mainly comes from scalding wastewater and cleaning wastewater, which contain a certain amount of mud, sand, suspended organic matter, protein, miscellaneous hair, grease, meat scraps and red hemoglobin; cooked food processing workshop wastewater mainly comes from raw material cleaning section , production section, packaging and forming section, these wastewaters contain a large amount of suspended organic matter, dissolved organic matter, fried oil and food additives; domestic sewage mainly comes ...
