Embodiment Construction

[0011] After the wastewater is desanded in the grit chamber and the water quality is adjusted in the regulating tank, it is upgraded to the high-efficiency CAF vortex air flotation system. The CAF vortex air flotation system removes most of the SS and COD in the wastewater, and then enters the contact oxidation tank for aerobic oxidation. biological treatment.

[0012] Major equipment:

[0013] 1. Grille

[0014] The waste water passes through the grid to remove part of the hair and suspended solids.

[0015] 2. Grit chamber

[0016] The advection type grit chamber is adopted, and the dust in the pond is regularly discharged through the sand discharge pipe at the bottom and enters the sand drying pond.

[0017] 3. Regulating pool

[0018] The water quality and quantity of meat processing wastewater fluctuate from time to time, and the regulating tank is used to adjust the water quantity.

[0019] 4. Lift the pump room

[0020] Two submersible sewage pumps are installed i...

Abstract

The invention discloses a meat processing waste water treatment process and belongs to the technical field of sewage treatment in food production industry. The invention provides the meat processing waste water treatment process. In the invention, according to the water quality of the waste water, discharge standards and the concrete conditions of an enterprise, an air-floating, contact oxidation and filtering process is adopted for processing meat processing waste water, so that a great amount of waste water discharged during the production of a meat food processing enterprise and pollutant such as hair, animal blood, fat and oil in the waste water are completely removed. Moreover, suspended solids (SS) content and chemical oxygen demand (COD) content of the waste water are high, chrominance is high, and waste water discharge is certainly periodic, so that the treatment process has the characteristics of low power consumption and low working noises, is stably operated, is convenient to manage and is easy to operate and maintain; and the waster water is discharged after meeting the national discharge standards.

Description

Technical field: [0001] The invention belongs to the technical field of sewage treatment in the food production industry. Background technique: [0002] With the continuous development of the vegetable basket project and the improvement of people's living standards, urban and rural residents demand fresh meat and safe meat, and the slaughter of livestock has been transferred from scattered and sporadic slaughter to centralized designated slaughter. These centralized slaughtering sites are all located in the urban-rural fringe, and the sewage discharge volume is large, the concentration is high, and there are many suspended solids. If effective treatment is not carried out, it will be directly discharged into the river, which will cause serious pollution to the environment. [0003] Meat slaughtering and processing enterprises have developed rapidly in recent years. At the end of 1990, there were 1,500 various meat processing enterprises in the country. In 2000, they had grow...
