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 recycling method of potato slag, waste water in a kind of potato starch production process.
Background technology
The normal raw material such as potato, 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 accessory substances.The potato slag contains organic matters such as a large amount of pectin, protein, starch granule, the viscosity height, and retention ability is strong, squeezing and drying and dehydrating difficulty, 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, the energy consumption height.The content of organic matter and COD value are too high in the waste water (generally not containing potato class rinse water), directly the exhaust emission environment.Though existing processing method can realize qualified discharge, equipment and operating cost height 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 at above-mentioned defective of the prior art, the recycling method of potato slag, waste water in a kind of potato starch production process is provided, can reclaim the organic matter in potato slag and the waste water in a large number, equipment and operating cost are low, processing method is efficient, simple, quick, gained potato slag can be used as feedstuff, gained waste water non-secondary pollution, reusable edible.
The technical scheme that realizes above-mentioned purpose is as follows:
The recycling 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 crushing method, as helping filter sorbing material 1;
The porous mineral matter that will can be used as feed addictive is prepared into the particle that size is 0.1～5mm through the physical crushing 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, enter filter and filter, obtain filter residue and filtrate; 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 by having added again the filtrate of gained, the thickness of feed layer that helps filter sorbing material 1 of adding is 20～80cm, produces filter residue and filtrate again;
(4) filter residue that step (2) and step (3) are obtained is made feedstuff by dry or fermentation;
(5) help the filter of filter sorbing material 2 to filter by having added again step (3) gained filtrate, the thickness of feed layer that helps filter sorbing material 2 of adding is 8～50cm, and this step gained filtrate can be used as the water for cleaning of potato class processing or enters water purification system.
Further, in the described step (2), in potato slag, waste water or potato slag and the waste water mixture after potato starch processing, 0.5～10% help filter sorbing material 1 or help filter sorbing material 2 that adds earlier its weight, mix the back and stir 10～30min, and then carry out the filter operation that enters 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 feed addictive in the described step (1) is attapulgite or diatomite.
The porous mineral matter attapulgite, the diatomite that drying are not had crop material such as rotten corn, wheat, Radix Codonopsis, Radix Angelicae Sinensis and can be used as feed addictive 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 potato processing gained, after stirring, squeeze or drying and dehydrating.The wet potato pulp water of potato can be divided content to be reduced to 55～65%, spin cycle shortening 2～3h from 85～90%.
Drying do not had the certain shearing of crop materials processes such as rotten corn, wheat, Radix Codonopsis, Radix Angelicae Sinensis, rub, pulverize (material 1, size 1～30mm) and the porous mineral matter attapulgite, diatomite that will can be used as feed addictive 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 filter respectively, material 1 bed thickness 20～80cm, material 2 bed thickness 8～50cm.
After solid content 2.34%, COD 30, potato class processing waste waters such as the potato of 820mg/L filtered absorption through material 1, solid content reduced to 0.70%, COD 7,690mg/L; After filtering absorption through material 2, solid content reduces to 0.04%, COD 1,521mg/L.
Beneficial effect of the present invention is as follows:
(1) can reclaim organic matter in potato slag and the waste water in a large number by recycling method of the present invention, and equipment and operating cost are low, processing method is efficient, simple, fast.
(2) with crop material etc. as the raw material that help the filter sorbing material, cheap, help the filter sorbing material can directly be used as feedstuff simultaneously.
(3) use and to help the filter sorbing material and help filter sorbing material dewatering efficiency to improve greatly than using, the water content of filter cake reduces, is easy to fragmentation, and rate of drying significantly improves, and permeability is good during fermentation.
(4) filter residue of processing back gained can be used as feedstuff through methods such as super-dry or fermentations after filtration.
(5) after filtration in the processed waste water content of organic matter and COD value reduce gained filtrate reusable edible greatly.
