Abstract
The invention provides a quick condensate agent for organic matters in rice dipping and washing waste water in the sugar industry and a treatment process. The condensate agent comprises a coagulation accelerator, a flocculant, a preservative and other matters, and is applicable to separating organic matters in the rice dipping and washing waste water in the broken rice sugar industry. The treatment process comprises a condensation reaction, settling separation and sand filter. The recycled organic matters are in accordance with the sanitation standard of feeds in China, and the treated clean water can be recycled in rice dipping and washing process.
Description
Technical field
The present invention relates to a kind of sugar industry of cracking rice and soak organic quick condensation agent and treatment process in the rice washing waste water, belong to wastewater treatment and chemical association technical field.
Background technology
In producing the process of malt syrup, crack rice or ageing rice through eluriate with the hot alkali dipping operation after can produce and contain organic matter and be about 1-3%, the waste water of CODcr ≈ 10000-30000 mg/litre.
Organic matter in the waste water is mainly carbohydrate such as protein and polysaccharide.As the basal component of feed, if they can be separated from water, enterprise both can reclaim by resource and benefit from it so, also can effectively reduce biochemical treatment load and the cost of follow-up sewage work accordingly.
The characteristics of this waste water are: 1) water temperature is 40 ℃, and it is rotten corrupt that abundant organic matter causes waste water to take place in a few hours, can't deposit.2) purpose that adopts traditional water treatment flocculant combination (polymeric aluminum+polyacrylamide series) can not reach rapid subsidence and separate organic matter.3) aluminum ion in the above-mentioned treatment agent and acrylamide monomer composition have certain toxicity to life entity, and the safe handling of feed is reclaimed in influence.
Develop satisfactory organic fast processing agent, and the recycling treatment that realizes soaking rice washing waste water is used as China's one of sugar industry problem demanding prompt solution of cracking rice always.
Summary of the invention
The purpose of this invention is to provide a kind of sugaring process that can be used for cracking rice and soak quick condensation agent and the treatment process of rice washing waste water.
A kind of sugaring process that can be used for cracking rice of the present invention soaks the quick condensation agent of rice washing waste water and the characteristics for the treatment of process are:
The waste water of eluriating through hot alkali dipping that is rich in organic matter of cracking rice is a kind of metastable colloid, bring out and the volume of flocculation agent is swept in the sex change of setting accelerator, capture under the synergy and cause wherein some soluble proteins, amino acid, organic matters such as oligose, and condensation rapidly and reunion take place in the suspended solid particulate of non-dissolving, and be precipitated out from water.Waste water reacts and the time ≈ that clarifies 15-20 minute, organic separation rate ≈ 60-70%, CODcr rate of descent＞50% of waste water.In addition, the water after the processing is limpid transparent, transmittance＞98%, can be again as soaking the reuse water of rice washing, and keep in 24 hours nonfermented rotten.
Quick condensation agent of the present invention is by setting accelerator, flocculation agent, several materials such as sanitas are formed, since they molecular structure and in nature respectively with some natural inorganic mineral, natural organic matter, and natural polymers is close, and is nontoxic, so the organic matter that reclaims meets the hygienic standard of China's feed.
The objective of the invention is to implement by following proposal:
To filling the ferric-polysilicate that adds 0.01-0.03% in the reaction tank that soaks rice washing waste water respectively by the mass percent of handling the water yield, adjust the pH=8 of water, to water, there are a large amount of tiny flcos to occur after the stirring and dissolving.Again to the potassium sorbate ethanolic soln of the cation modified starch that wherein adds 0.0002-0.0005% and the 0.03% (mass ratio of potassium sorbate and ethanol=1:1), slowly be stirred to dissolving fully, when occurring a large amount of condensation flco in the water, water is incorporated in the post precipitation pond, staticly settled 10-15 minute.Being incorporated into the upper strata clear water by average particle size range at last is in the sand filter of 1-3 millimeter, the residual flco of filtering.
The clear water that leaches can feed back to the elutriation/immersion operation of cracking rice again and recycle.The oven dry immediately after centrifuge dehydration of throw out in the settling tank namely can be used as feed.
Embodiment
Embodiment 1:
To filling the ferric-polysilicate that adds 200g in the reaction tank that 1000kg soaks rice washing waste water, adjust the pH=8 of water, to water, there are a large amount of tiny flcos to occur after the stirring and dissolving.The potassium sorbate ethanolic soln for preparing by the mass ratio of 1:1 in advance to the cation modified starch that wherein adds 3g and 300g slowly is stirred to dissolving fully again.When occurring a large amount of condensation flco in the water, water is incorporated in the next settling tank, staticly settled 10-15 minute.Being incorporated into the upper strata clear water in the settling tank by average particle size range at last is in the sand filter of 1-3 millimeter, the residual flco of filtering.
Clear water after the filtering feeds back to the elutriation/immersion operation of cracking rice as cycling use of water.
The oven dry immediately after centrifuge dehydration of throw out in the settling tank obtains animal-feed.
