Problems solved by technology

At present, some enterprises secretly discharge untreated wastewater into rivers and lakes, and even directly discharge wastewater into farmland. Due to the corruption of blood components, the rivers and lakes emit an unpleasant smell of corpses, causing serious pollution to the environment and social impact. Therefore, it is urgent to develop and utilize waste water scientifically and rationally.

Embodiment 1

[0023] Embodiment 1: To the treatment of 100kg pig blood wastewater

[0024] Put 100kg of fresh pig blood wastewater into the collection pool, put in a mixed solution of 100mg of sodium carbonate and ammonia water and stir it until uniform, measure the pH to 10, control the temperature at 85°C, wait for the reaction for 5 minutes, then add 98% sulfuric acid 12ml, adjust pH8 to react for 2 minutes, let stand for 30min, make it static and separate. Turn on the water pump to draw out the supernatant, which is free from impurities, odorless and transparent.

Embodiment 2

[0025] Embodiment 2: to the processing of 100kg bovine blood wastewater

[0026] Put the wastewater containing 100kg of fresh cow blood into the collection pool, put in the mixed solution of 100mg of sodium carbonate and ammonia water and stir it until uniform, measure the pH to 10.4, control the temperature at 90°C, wait for the reaction for 5 minutes, add 98 ﹪12ml of sulfuric acid, adjust the pH to 8.5 and wait for 2 minutes to react, then let it stand for 30 minutes to make it stand still and separate into layers. Turn on the water pump to draw out the supernatant, which is free from impurities, odorless and transparent.

Embodiment 3

[0027] Embodiment 3: to the treatment of 100kg sheep blood wastewater

[0028] Put the waste water containing 100kg of fresh sheep blood into the collection pool, put in the mixed solution of 100mg of sodium carbonate and ammonia water and stir it until uniform, measure the pH to 9.9, control the temperature at 90°C, wait for the reaction for 5 minutes, add 98 ﹪12ml of sulfuric acid, adjust the pH to 8.3 and wait for 2 minutes to react, then let it stand for 30 minutes to make it stand still and separate into layers. Turn on the water pump to draw out the supernatant, which is free from impurities, odorless and transparent.

Abstract

The invention discloses a treatment system of meat processing waste water. The treatment system comprises a waste water collecting pool, a buoyancy grille, a blood purification pool, a backflow pool, an aeration pool, an integral treatment pool, a sterilization pool, a buffer pool and the like. According to the system, an observation opening and a chemical adding opening are formed in the top of the backflow pool; the backflow pool adopts a fully sealed design; the added chemical is a luminal reagent. The buoyancy grille used by the system does not need an electric facility, so that the goal of removing suspended substances completely by the physical effects is achieved. For slaughterhouse waste water processed by the system, the animal blood treatment effect can reach 98.5 percent or higher; the COD (chemical oxygen demand) treatment effect can reach 94.2 percent; the suspended solids treatment effect can reach 96.8 percent; the ammonia nitrogen treatment effect can reach 94.3 percent; the escherichia coli and microbe treatment effect can reach 99 percent or higher.

Description

technical field [0001] The invention relates to a treatment system for meat processing wastewater, which belongs to the field of wastewater treatment in environmental protection. Background technique [0002] Due to the continuous improvement of people's living standards, people's demand for various meats is gradually increasing. People are not limited to pigs, cattle, sheep, fish, but also chicken, duck, goose, etc., so the number of various slaughterhouses is constantly increasing. The amount of animal blood is also increasing, and the amount of wastewater generated during the processing of animal blood products is also increasing. The wastewater mainly comes from washing equipment, washing and processing sites, etc. The wastewater mainly contains wastewater mainly in processing Produced during the process, that is, vehicle duck cage flushing water; live chicken slaughter, scalding, hair removal flushing, etc. Slaughter wastewater contains a large amount of intestinal dig...
