Abstract
The invention discloses a method for treating collagen casing wastewater. The method comprises the following steps of: sequentially arranging an alkaline water sedimentation tank, an acid water storage pool and a precipitate floating pond; mixing alkaline water deposited in alkaline water sedimentation tank and acid water of the acid water storage pool; controlling the pH value of mixed wastewater to be 6-9; introducing the mixed wastewater into the precipitate floating pond; and taking out precipitates and supernatants from the precipitate floating pond to complete treatment of the collagen casing wastewater, wherein the residence time of the precipitates and the supernatants lasts for a period of not more than 30 days and is as short as possible according to actual treatment needs. The wastewater treated by using the method disclosed by the invention achieves the purposes of recycling collagens and effectively reducing pollutants in the wastewater, and meanwhile the method has the advantages of stability in operation, low investment and operating expenses and convenience for management.
Description
Technical field
The invention belongs to technical field of waste water processing, particularly a kind of albumen sausage casing method of wastewater treatment.
Background technology
Albumen sausage casing can discharge the too high or too low waste water of a large amount of pH values in process of production, in this waste water, except containing a large amount of acidity or alkaline matter, also contains that to take collagen protein etc. be main organism; Collagen protein is a kind of biological polymer substance, is one of critical starting material of tool of biotech industry; And if the collagen protein being included in waste water does not reclaim, not only waste resource, and, along with its biodegradable process, larger on the impact of follow-up waste water structures.
Summary of the invention
Object of the present invention is exactly for the problems referred to above, and a kind of albumen sausage casing method of wastewater treatment is provided, and the method is separated with acid waste water by alkaline waste water, and carries out the neutralization of control condition, and then carries out the separation of collagen protein.
Concrete steps are:
(1) set gradually buck settling tank, sour water storage pool and precipitation upper floating tank, wherein buck settling tank is connected with one end of channel respectively with sour water storage pool, and the other end of channel is connected with precipitation upper floating tank.
(2) alkaline waste water enters buck settling tank and makes buck through precipitation, and acid waste water enters sour water storage pool and makes sour water.
(3) step (2) makes buck and sour water mix in channel, and the pH value of the waste water after mixing is controlled at 6 ~ 9.
(4) waste water after step (3) is mixed enters precipitation upper floating tank, at precipitation upper floating tank, takes out throw out and supernatant, completes albumen sausage casing wastewater treatment.
The residence time of described throw out and supernatant should, no longer than 30 days, need the residence time more short better according to actual treatment.
The present invention processes albumen sausage casing waste water, can obtain high efficiente callback collagen protein and reduce the object of organism and ammonia-nitrogen content in waste water, has the advantages such as stable, investment working cost is low, convenient management simultaneously.
Embodiment
embodiment:
The waste water of processing in the present embodiment is taken from the albumen sausage casing waste water that certain enterprise produces.
(1) set gradually buck settling tank, sour water storage pool and precipitation upper floating tank, wherein buck settling tank is of a size of: long * wide * high=2 meters * 5 meters * 1.5 meters, be provided with precipitation tipping bucket, lye pump and slag stock pump, and by slag stock pump, lime is pumped; Sour water storage pool is of a size of: long * wide * high=20 meters * 10 meters * 4 meters, be provided with acid pump; Precipitation upper floating tank is of a size of: long * wide * high=10 meters * 5 meters * 2.5 meters; Buck settling tank is connected with one end of channel respectively with sour water storage pool, and the other end of channel is connected with precipitation upper floating tank.
(2) alkaline waste water enters buck settling tank and makes buck through precipitation, and acid waste water enters sour water storage pool and makes sour water.
(3) step (2) makes buck and sour water pump in channel and mix via lye pump and acid pump respectively, and the pH value of the waste water after mixing by the control of pH value on-line Control device is 7.5.
(4) waste water after step (3) is mixed enters precipitation upper floating tank, and formed supernatant and throw out stop and take out afterwards for 15 days, complete albumen sausage casing wastewater treatment.
Through the waste water quality after processing, greatly improve, the waste water quality contrast situation before and after processing is in Table 1.
Table 1 is processed front and back variation of water
| ? | Chemical oxygen demand (COD) (COD), mg/litre | Clearance |
| Buck settling tank buck | 1856.6 | ? |
| Sour water storage pool sour water | 243 | ? |

Claims (1)
1. an albumen sausage casing method of wastewater treatment, is characterized in that concrete steps are:
(1) set gradually buck settling tank, sour water storage pool and precipitation upper floating tank, buck settling tank is connected with one end of channel respectively with sour water storage pool, and the other end of channel is connected with precipitation upper floating tank;
(2) alkaline waste water enters buck settling tank and makes buck through precipitation, and acid waste water enters sour water storage pool and makes sour water;
(3) step (2) makes buck and sour water mix in channel, and the pH value of the waste water after mixing is controlled at 6 ~ 9;
(4) waste water after step (3) is mixed enters precipitation upper floating tank, at precipitation upper floating tank, takes out throw out and supernatant, completes albumen sausage casing wastewater treatment;
The residence time of described throw out and supernatant should, no longer than 30 days, need the residence time more short better according to actual treatment.
