Problems solved by technology
The discharge of these organic waste water into the water body consumes a large amount of dissolved oxygen. If it is discharged directly without treatment, it will pollute the environment.
[0006] The State Environmental Protection Administration pointed out in the "Tenth Five-Year Plan" of the National Environmental Science and Technology Development: Continue to study the wastewater pollution control technology of the starch industry as an important content. It can be seen that the wastewater in the starch production process must be treated before it can be discharged. Treatment methods can generally be divided into biochemical methods and chemical flocculation-sedimentation methods. No matter which method is used, it will cost a lot of material costs. If the discharged wastewater is directly used after a little treatment, it will not only reduce pollution, but also reduce pollution. Treatment cost kills two birds with one stone. There is no report about the wastewater generated in the corn wet starch production process, that is, the corn soaking water can promote plant seed germination and flowering

Embodiment
[0033] 1. Collection of corn soaking water
[0034] In starch production enterprises, the waste water produced by the corn wet starch production process is collected, mixed, and then further concentrated by a three-effect falling film evaporator. Specifically, the source of corn soaking water is obtained from the following three parts:
[0035] The first part: Soak the corn in the soaking tank with sulfurous acid. There are 8 to 12 soaking tanks. During the soaking process, the corn stays in the tank and uses a pump to circulate the soaking liquid in the tank while moving forward. For transportation, always keep the new sulfurous acid solution in contact with the corn for the longest soaking time, that is, the corn that is about to end soaking, to maintain the best soaking effect; the soaking temperature is 60±10°C, the sulfurous acid concentration during soaking is 0.2%, and the soaking time 70~100h; the solution after soaking is the first part of corn soaking water.

The invention discloses corn soaking water and application thereof, belongs to the technical field of wastewater reutilization, and specifically relates to reutilization of residual wastewater (the corn soaking water) in a corn wet starch production technology. By utilizing the corn soaking water, pollution to the environment and the wastewater treatment cost can be reduced; the corn soaking wateris capable of promoting seed germination and increasing a germination rate of seeds and is capable of applying the corn soaking water as fertilizer to soil, not only the waste utilization value can be increased, blooming of plants can also be promoted, a growth period of the plants can be shortened, and a promotion function on growth of the plants is obtained.
Description
technical field [0001] The invention belongs to the technical field of waste water reuse, and in particular relates to the reuse of waste water (corn soaking water) remaining in corn wet starch production technology, more specifically the application of corn soaking water in promoting plant seed germination and plant flowering. Background technique [0002] In the wet starch production process, the wastewater generated is mainly in the following processes, specifically: [0003] Washing water is produced in the impurity cleaning process section. When corn is fed, it is hydraulically transported to the soaking system. The ratio of corn to transport water is 1:2.5~3, and the temperature is 35~50 degrees. After the conveyed water passes through the dehydration screen to remove impurities, the wet corn enters the soaking tank, and the washing water is discharged. In addition, when the soaked corn is washed, a small amount of sewage is also discharged. The characteristics of th...
