Abstract
The invention relates to the field of industrial production of potato starch and provides a method for recycling potato residue and waste water in the production process of potato starch. The method mainly comprises the following steps of: respectively pulverizing crop straws and porous mineral substances used as a feedstuff additive into certain size of particles as filtering-assisted adsorbing materials through a physical method; and carrying out filtering treatment by stages by utilizing the two filtering-assisted adsorbing materials in a process of recycling potato residue and waste water organic matters generated when processing the potato starch. The recycled organic matters, such as small particle starch, protein, polysaccharide, and the like and the filtering-assisted adsorbing materials can be together used as feedstuff materials, and the purpose of purifying the waste water is also achieved; and the purified water can be used as washing water for potato processing directly or through precipitating.
Description
Technical field
The present invention relates to potato starch industrial production field, particularly, relate to the recycle method of potato slag, waste water in a kind of potato starch production process.
Background technology
The normal starting material such as yam, sweet (red) potato, cassava that adopt of potato starch processing will produce a large amount of wet potato slag and waste water in process of production, contain organic matters such as amounts of protein, polysaccharide in these by products.The potato slag contains organic matters such as a large amount of pectin, protein, starch granule, and viscosity is high, and retention ability is strong, squeezing and drying and dehydrating difficulty, and COD (COD) value of deviating from water is also than higher.At present, wet potato slag main methods is to dry behind the direct press dewatering, but dewatering efficiency is low, and rate of drying is slow, and energy consumption is high.Organic content and COD value are too high in the waste water (generally not containing potato class rinse water), directly the exhaust emission environment.Though existing treatment process can realize qualified discharge, equipment and running cost are high, are difficult to drop into practical application, and also there is secondary pollution in some, has influenced the Sustainable development of surrounding environment and potato starch processing industry.
Summary of the invention
The objective of the invention is to above-mentioned defective of the prior art; The recycle method of potato slag, waste water in a kind of potato starch production process is provided, can reclaims the organic matter in potato slag and the waste water in a large number, equipment and running cost are low; Treatment process is efficient, simple, quick; Gained potato slag can be used as feedstuff raw material, gained waste water non-secondary pollution, reusable edible.
The technical scheme that realizes above-mentioned purpose is following:
The recycle method of potato slag, waste water comprises the steps: in a kind of potato starch production process
(1) helps the preparation of filtering sorbing material 1,2
Crop material is prepared into the particle that size is 1～30mm through the physical pulverization method, as helping filter sorbing material 1;
The porous mineral matter that will can be used as fodder additives is prepared into the particle that size is 0.1～5mm through the physical pulverization method, as helping filter sorbing material 2;
(2) with the mixture of the potato slag in the potato starch production process, waste water or potato slag and waste water, get into filter and filter, obtain filter residue and filtrating; The potato slag in the wherein said mixture and the weight ratio of waste water are 1: 0.1～5;
(3) help the filter of filter sorbing material 1 to filter through having added again the filtrating of gained, the bed thickness that helps filter sorbing material 1 of adding is 20～80cm, produces filter residue and filtrating again;
(4) filter residue that step (2) and step (3) is obtained is processed feedstuff raw material through dry or fermentation;
(5) help the filter of filter sorbing material 2 to filter through having added again step (3) gained filtrating, the bed thickness that helps filter sorbing material 2 of adding is 8～50cm, and this step gained filtrating can be used as the water for cleaning of potato class processing or gets into water purification system.
Further; In the said step (2); In potato slag, waste water or potato slag and the waste water mixture after potato starch processing; Add earlier 0.5～10% help filter sorbing material 1 or help filter sorbing material 2 of its weight, mix the back and stir 10～30min, and then carry out the filter operation of the entering filter described in the step (2).
Further, the crop material in the described step (1) is the stalk of corn, wheat, Radix Codonopsis or Radix Angelicae Sinensis.
Further, the porous mineral matter that can be used as fodder additives in the described step (1) is attapulgite or zeyssatite.
The porous mineral matter attapulgite, the zeyssatite that drying are not had crop material such as septic corn, wheat, Radix Codonopsis, Radix Angelicae Sinensis and can be used as fodder additives are through certain shearing, rub, pulverize the back as helping the filter sorbing material.Help the filter sorbing material to add in 0.5～10% ratio in the wet potato slag of potato starch such as yam processing gained, after stirring, squeeze or drying and dehydrating.Can divide content to be reduced to 55～65%, spin cycle shortening 2～3h the wet potato pulp water of yam from 85～90%.
Drying do not had the certain shearing of crop materials processes such as septic corn, wheat, Radix Codonopsis, Radix Angelicae Sinensis, rub, pulverize (material 1; Size 1～30mm) and the porous mineral matter attapulgite, zeyssatite that will can be used as fodder additives handle through certain methods such as pulverizing that (material 2 obtains two kinds of filtering adsorbing materials after the size 0.1～5mm).Material 1 and material 2 are seated in compacting in the filtration unit respectively, material 1 bed thickness 20～80cm, material 2 bed thickness 8～50cm.
Solid substance 2.34%, COD 30, potato class processing waste waters such as the yam of 820mg/L be through after material 1 Filtration Adsorption, and solid substance reduces to 0.70%, COD 7,690mg/L; Through after material 2 Filtration Adsorption, solid substance reduces to 0.04%, COD 1,521mg/L.
Beneficial effect of the present invention is following:
(1) can reclaim the organic matter in potato slag and the waste water in a large number through recycle method of the present invention, and equipment and running cost are low, treatment process is efficient, simple, fast.
(2) with crop material etc. as the starting material that help the filter sorbing material, cheap, help the filter sorbing material can directly be used as feedstuff raw material simultaneously.
(3) use and to help the filter sorbing material and help filter sorbing material dewatering efficiency to improve greatly than using, the water cut of filter cake reduces, is easy to fragmentation, and rate of drying significantly improves, and permeability is good during fermentation.
(4) filter residue of gained can be used as feedstuff raw material through methods such as super-dry or fermentations after filtering processing.
(5) organic content and COD value reduce greatly in the filtration processed waste water, gained filtrating reusable edible.
