Abstract
The invention relates to the field of the wastewater treatment in the environmental engineering, and in particular to the field of the wastewater treatment in the papermaking industry. The treatment method of the industrial papermaking wastewater comprises the steps of: a. filtering impurity out of discharged papermaking wastewater by a filter screen; b. discharging the papermaking wastewater into a water collecting pool for collecting and storing; c. treating the papermaking wastewater by means of air flotation or precipitation; d. discharging the papermaking wastewater into a precipitating pool to precipitate the impurity; e. pumping the wastewater into an anaerobic pool and a facultative pool; f. discharging into a stabilizing pool for standing for 3-5 days; g. discharging into an adjusting pool, and feeding green planktonic algae-enriched pool water; and h. feeding into a surface runoff wetland system. The method can be used for treating the industrial papermaking wastewater with higher wastewater concentration, and the water purified by the treatment method is the discharged water which is clear in color, and tasteless.
Description
Technical field
The present invention relates to the field of waste water treatment in the environmental engineering, more relate to the field of waste water treatment in the paper industry.
Background technology
Pollutant levels height in the paper waste, composition are complicated, contain a large amount of paper making raw materials and pharmaceutical chemicals, and oxygen consumption is serious, causes the paper waste difficult treatment, becomes one of industry of serious environment pollution.If paper waste is directly discharged the meeting serious environment pollution, so must be through purifying treatment.And the SS of waste paper making wastewater, COD concentration are higher, and COD then is made up of non-solubility COD and solvability COD two portions, and non-solubility COD accounts for the major part that COD forms total amount usually, and when SS was removed in the waste water, most non-solubility COD were removed simultaneously.Therefore, to handle the subject matter that will solve be to remove SS and COD to waste paper making wastewater.
Generally can adopt air supporting or intermediate processing for paper waste,, can remove most SS, remove most of non-solubility COD and being partly dissolved property COD and BOD5 simultaneously by dosing coagulant.Its typical processing technological flow is as follows: waste water → filtering net → water collecting basin → air supporting or precipitation → discharging.Air supporting and precipitation are materilization freatment method, and treatment effect is relevant with the equipment of selecting for use, processing parameter, coagulating agent etc., but effect still is not ideal enough.Therefore, need a kind of clean more effectively treatment process,,, really realize the target of sewage recycling and continuous service reutilization of the sewage in order to avoid cause pollution to environment to paper waste.
Summary of the invention
Therefore, the objective of the invention is a kind of new processing method that method that the method by ecology combines with the air supporting or the precipitator method of traditional paper waste has realized paper waste is carried out purifying treatment.The invention provides and a kind ofly not only can effectively administer paper waste, realize the zero release of waste water substantially, and closed cycle utilizes nutritive substance and moisture content in the waste water to produce paper making raw material (or other garden crop), realize the resource utilization of paper waste.
Industrial technological process for the treatment of papermaking method of the present invention comprises step:
Step a: the paper waste of discharge is by the filtering net impurity screening;
Step b: paper waste enters the water collecting basin collection storage again;
Step c: utilize air supporting processing or precipitation process paper waste;
Steps d: enter settling tank and carry out contamination precipitation;
Step e: pump into anaerobic pond and facultative lagoon, and add bio-feritlizer in the anaerobic pond, the paper waste residence time is 4～5 months, temperature＞10 of control anaerobic pond and facultative lagoon ℃;
Step f: enter stabilization pond and left standstill 3～5 days;
Step g: enter equalizing tank, the Chi Shui that is rich in green planktonic algae of introducing;
Step h: enter the rainwash wet land system, described rainwash wet land system is the rectangular wetland field that irrigation canals and ditches distribute, plantation wetland crop on the wetland field.
Industrial technological process for the treatment of papermaking method of the present invention can the higher paper waste of waste strength, reaches water quality look clear tasteless discharge water after purifying through disposal methods of the present invention.And the water quality after method of the present invention is handled is better than the primary standard of paper industry water pollutant discharging, and the required clear water of the equalizing tank that can reflux back, need not efflux, and realizes perfect purification self-circulation.
Embodiment
Industrial technological process for the treatment of papermaking method of the present invention comprises step:
Step a: the paper waste of discharge is by the filtering net impurity screening;
Step b: paper waste enters the water collecting basin collection storage again;
Step c: utilize air supporting processing or precipitation process paper waste;
Steps d: enter settling tank and carry out contamination precipitation;
Step e: pump into anaerobic pond and facultative lagoon, and add bio-feritlizer in the anaerobic pond, the paper waste residence time is 4～5 months, temperature＞10 of control anaerobic pond and facultative lagoon ℃; Wherein, described bio-feritlizer can be to derive from human and animal excreta.Anaerobic pond and facultative lagoon carry out the series connection of two pools earlier, carry out two group parallel connections again.Preferably, anaerobic pond I connects with facultative lagoon I, anaerobic pond II connects with facultative lagoon II, two sets in parallel operation, and wherein the anaerobic pond total area is 1000 mu, 2.5 meters of projected depths, 1500 mu of the facultative lagoon total areas, 1.5 meters of projected depths, water stops 5 first quarter moons of duration, do not need summer to handle, winter, the plastic covering film temperature remained on more than 10 ℃.
Step f: enter stabilization pond and left standstill 3～5 days;
Step g: enter equalizing tank, the Chi Shui that is rich in green planktonic algae of introducing;
Step h: enter the rainwash wet land system, described rainwash wet land system is the rectangular wetland field that irrigation canals and ditches distribute, plantation wetland crop on the wetland field.Preferably, can on the wetland field, plant metasequoia, reed etc. and introduce the moss crop, and the clear water in river course carries out desalinization of soil by flooding or leaching alkali to the wetland field near can regularly introducing, to guarantee the growth of crop new talent.
Although specifically show and introduced the present invention in conjunction with preferred embodiment; but the those skilled in the art should be understood that; in the spirit and scope of the present invention that do not break away from appended claims and limited; can make various variations to the present invention in the form and details, be protection scope of the present invention.
