Abstract
The invention relates to a method for treating fruit processing waste water. The method comprises the following treatment steps of: (1) centrifugalizing the fruit processing waste water at the rotation speed of 3500 rpm for 20-30 minutes; (2) removing the precipitations of the fruit processing waste after centrifugalization, and taking a supernatant; (3) filtering the fruit processing waste through a membrane, wherein the membrane filtering molecular weight is 5000; (4) introducing the fruit processing waste to a membrane with the molecular weight of 1000-2000; (5) finally introducing the fruit processing waste to XDA-8 macroporous adsorption resin, wherein the ratio of sample loading quantity and resin weight is 8:1, the sample loading speed is 2-3 BV/h; (6) collecting effluent liquid. According to the method, the chemical oxygen consumption value of the treated fruit processing waste is reduced from 371 mg/L to 26-34 mg/L, and the total sugar content is reduced from 642 mg/L to 65-73 mg/L.
Description
Technical field
The present invention relates to a kind for the treatment of process of waste water, particularly relate to a kind for the treatment of process of fruit processing waste water.
Background technology
Some fruits collected return after, a lot of fruits have been processed to preserved fruit or can, in the course of processing of these fruits, have a large amount of waste water and produce, in these fruit processing waste waters, chemical oxygen demand value is larger, directly discharge can bring a large amount of pollutions.Not only in fruit processing waste water, chemical oxygen demand value is large, and its total sugar content is also larger, and unprocessed discharge easily produces the problem of eutrophication afterwards.The existence of these problems, the waste water that needs us to produce fruit processing is processed, and discharges after reaching emission standard again, prevents the further pollution of fruit processing waste water to environment.
Summary of the invention
The technical problem solving: the Chemical Oxygen Demand in Wastwater value and the total sugar content that produce after fruit processing are higher, ordinary method is less to chemical oxygen demand value and total sugar content reduction, still the problem of serious environment pollution.
Technical scheme: the invention discloses a kind for the treatment of process of fruit processing waste water, treatment step is as follows: (1) carries out fruit processing waste water centrifugal, centrifugal rotational speed is 3500rpm, centrifugation time is 20min～30min; (2) precipitation of centrifugal rear removal fruit processing waste water, gets supernatant liquid; (3) fruit processing waste water is passed through to membrane filtration, membrane filtration molecular weight is 5000; (4) film that is 1000～2000 by fruit processing waste water by molecular weight again; (5) finally fruit processing waste water is passed through to XDA-8 macroporous adsorbent resin, applied sample amount is with resin quality than being 8:1, and loading flow velocity is 2BV/h～3BV/h; (6) collect effluent liquid, prepare and process rear fruit processing waste water.
Filtering membrane described in a kind for the treatment of process of fruit processing waste water is preferably poly tetrafluoroethylene.
A kind for the treatment of process XDA-8 macroporous adsorbent resin of fruit processing waste water is preferably the rear resin of activation.
In a kind of disposal methods process of fruit processing waste water, loading flow velocity is preferably 3BV/h.
In a kind of process method step of fruit processing waste water (4), fruit processing waste water is preferably to 1000 film by molecular weight.
Beneficial effect: through after disposal methods of the present invention, the chemical oxygen demand value of fruit processing waste water is down to 26mg/L～34mg/L from 371mg/L, and total sugar content is down to 65mg/L～73mg/L from 642mg/L.
