Abstract
The present invention relates to the waste water processing field in environmental projects, and relates to the waste water processing field in paper manufacturing industry, in particular to a new technique for the clarification of paper manufacturing waste water by using a synusiologic method. The synusiologic processing method of the paper manufacturing waste water of the present invention comprises the steps of waster water discharge, mesh gauze filtration, collecting basin bleeding, air supporting or sendimentation process, sendimentation basin bleeding, anaerobic pond and facultative pond pumping, fertilizer feeding, stabilization pond bleeding, adjusting basin bleeding, clean water leading-in and ground runoff wetland system entrance. The synusiologic processing method of the paper manufacturing waste water of the present invention can enable the COD value and the SS value of complex waste water to obviously reduce, the pH value is closed to 7, and water quality is clean without flavor. The water quality is superior to the one-grade standard of water contaminant discharge of the paper manufacturing industry, and clean water needed by an adjusting basin can flow back into the adjusting basin without outer discharge, so complete cleaning self circulation is realized.
Description
Technical field
The present invention relates to the field of waste water treatment in the environmental engineering, relate to the field of waste water treatment in the paper industry, especially relate to and utilize ecological method paper waste to be carried out a kind of new processing method of purifying treatment.
Background technology
Paper waste (black digestion liquid, middle-stage wastewater, plain boiled water etc.) generating capacity is big, ton product water loss is big, wherein major part is discharged as waste water, Pollutant levels height in the waste water, composition are complicated, contain a large amount of paper making raw materials and pharmaceutical chemicals, oxygen consumption is serious, cause the paper waste difficult treatment, become one of industry of serious environment pollution, wherein especially to solve the difficulty maximum that alkaline straw pulp paper pollutes.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 → screen cloth → 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.
Technical scheme of the present invention is as follows:
The ecological treatment method of paper waste of the present invention comprises step:
Step 101: discharge waste water; Enter
Step 102: screen filtration; Enter
Step 103: enter water collecting basin; Enter
Step 104: air supporting or precipitation process; Enter
Step 105: enter settling tank; Enter step 1061 and step 1062,
Step 1061: pump into anaerobic pond; Also increase a step 10611: add fertilizer; Enter step 107 again,
Step 1062: pump into facultative lagoon; Enter step 107,
Step 107: enter stabilization pond; Enter
Step 108: enter equalizing tank; Also increase a step 1081: introduce clear water; Enter again
Step 109: enter the rainwash wet land system.
Further, the fertilizer in the described step 10611 is nitrogenous fertilizer and phosphate fertilizer.
Further, described nitrogenous fertilizer and phosphate fertilizer are to derive from human and animal excreta.
Further, the retention time of sewage of anaerobic pond and facultative lagoon is 4～5 months in described step 1061 and the step 1062, temperature＞10 of control anaerobic pond and facultative lagoon ℃.
Further, anaerobic pond and facultative lagoon carry out the series connection of two pools earlier in described step 1061 and the step 1062, carry out two group parallel connections again.
Further, the clear water in the introducing equalizing tank of described step 1081 is rich in green planktonic algae.
Further, described rainwash wet land system is the rectangular wetland field that irrigation canals and ditches distribute, plantation wetland crop on the wetland field.
The ecological treatment method of paper waste of the present invention can make comprehensive wastewater concentration C OD=1800～3500mg/L, SS=400～560mg/L, the paper waste of PH＞11 is after disposal methods purification of the present invention, COD＜120mg/L, SS＜80mg/L, pH value are near about 7, and the water quality look tasteless is clearly, water quality 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, realize perfect purification self-circulation.
