Background
Edible gelatin is a widely used natural additive in the food industry, and is usually prepared by an alkaline process, and the raw materials are seaweed and konjak. The source of the wastewater is mainly alkaline water generated after the seaweed is washed. The edible gelatin wastewater has high pH value, contains a large amount of organic matters, inorganic salts and sulfides, also contains substances which are difficult to degrade in a physical and chemical manner, and belongs to industrial wastewater which is difficult to treat. Because the excessive pH value enters a sewage treatment system and cannot be borne by a conventional activated sludge method, when the edible gelatin wastewater is treated by the traditional method, hydrochloric acid and sulfuric acid are added to adjust the pH value before the wastewater enters the sewage system, and for enterprises, a large amount of capital is required to be invested to purchase the hydrochloric acid and the sulfuric acid, so that the method is extremely unfriendly to the environment. After entering a sewage treatment system, the gelatin wastewater often generates a large amount of sludge, and the sludge treatment method is generally discarded after being discharged and is also unfavorable for the ecological environment.
The acid-producing bacteria is a microbe capable of utilizing organic matter in water to produce acid through fermentation, and features that the organic matter difficult to degrade in water is converted into soluble organic matter, which is then fermented to produce acid. When the bacillus subtilis is used in alkaline wastewater, the bacillus subtilis can neutralize the alkali in the wastewater and remove COD (chemical oxygen demand) of the wastewater, so that the bacillus subtilis has great significance in the treatment of the alkaline wastewater.
