Abstract
The invention relates to a method for treating wastewater generated in the carbonization of bamboo. The method comprises the steps of feeding wastewater generated in carbonization of bamboo into a reaction kettle, heating to above 100 DEG C; introducing the steam generated by heating into a cooling pipeline to form condensed water, discharging the condensed water into a reservoir or reservoir containing algae and plankton; adding a certain amount of biological bacteria into the reservoir or reservoir containing algae and plankton and carrying out biological purification for a period of time until the wastewater meets the emission or edible standard by detection; discharging and drying sediments generated in the reaction kettle after heating, wherein the dried substance is used as a fuel for the reaction kettle; and taking the product generated by burning the dried substance as a fertilizer. Due to the adoption of the method disclosed by the invention, the wastewater generated in the carbonization can reach the emission standard and even edible standard, the sediments produced in the wastewater treatment process can be also taken as a fuel, and the burnt substance can be used as a fertilizer.
Description
Technical field
The present invention relates to the method for wastewater treatment producing in a kind of charing bamboo wood process.
Background technology
At present, in the course of processing of bamboo and wood goods, conventionally need to pass through charring process, by steam, bamboo and wood be carried out to pyrolysis processing, and after charing, can produce a large amount of waste water, if discharge arbitrarily can produce very big pollution to river and farm crop.
Summary of the invention
The object of this invention is to provide the waste water that can make can to produce after charing and reach the method for wastewater treatment producing in a kind of charing bamboo wood process of discharging food sanitation standard even.
The technical scheme that the present invention takes is: the method for wastewater treatment producing in a kind of charing bamboo wood process, is characterized in that it comprises following process: A, the waste water generating after bamboo charcoal is sent in reactor and is heated to more than 100 DEG C; B, will add thermogenetic steam and pass into cooling duct, and enter in water reservoir or contain in algae and in planktonic water reservoir after forming water of condensation; C, at water reservoir or containing in algae, add a certain amount of biological bacteria to carry out after the biopurification of for some time in planktonic water reservoir, reach after testing discharge or food sanitation standard; D, the settling that produces in reactor after heating is discharged dry, dry thing uses as the fuel of reactor; D, the material that dry thing burning is formed are afterwards done fertilizer processing.
Adopt the present invention, the waste water that not only can make can to produce after charing reaches and discharges even food sanitation standard, also can make full use of settling in wastewater treatment process simultaneously and make fuel and use, and material after burning can be done again fertilizer processing.
Embodiment
Below in conjunction with specific embodiment, invention is described further.It comprises following process:
One, the waste water generating after bamboo charcoal is sent in reactor and is heated to more than 100 DEG C.
Two, will add thermogenetic steam and pass into cooling duct, and form and enter after water of condensation in water reservoir to till full.Can be directly used in industrial process waters.
Three, in water reservoir, add a certain amount of biological bacteria (as yeast, actinomycetes and filamentous fungus etc.) to carry out after the biopurification of for some time, reach after testing discharge or food sanitation standard.Or the biological bacteria (as yeast, actinomycetes and filamentous fungus) etc. that adds small amount containing in algae, in the water reservoir of planktonic organism (as Value of Spartina Anglica, Scirpus tabernaemontani, Herba Eichhorniae, duckweed, hornwort, water caltrop etc.) carries out reaching discharge or food sanitation standard through detecting after the biopurification of for some time.Biological bacteria consumption wherein uses five-day BOD (BOD5) and these two parameters of chemical oxygen demand (COD) (COD) as the overall target of weighing biological degradation Organic pollutants in water body conventionally.
Four, the settling producing after heating is discharged to natural air drying and be dried in reactor, dry thing uses as the fuel of reactor.
Five, the material forming after dry thing burning is done to fertilizer processing.
Claims (1)
1. the method for wastewater treatment producing in charing bamboo wood process, is characterized in that it comprises following process: A, the waste water generating after bamboo charcoal is sent in reactor and is heated to more than 100 DEG C; B, will add thermogenetic steam and pass into cooling duct, and enter in water reservoir or contain in algae and in planktonic water reservoir after forming water of condensation; C, at water reservoir or containing in algae, add a certain amount of biological bacteria to carry out after the biopurification of for some time in planktonic water reservoir, reach after testing discharge or food sanitation standard; D, the settling that produces in reactor after heating is discharged dry, dry thing uses as the fuel of reactor; D, the material that dry thing burning is formed are afterwards done fertilizer processing.
