With reference to Fig. 2 and Fig. 1, by F-T synthetic wastewaters processing system of the present utility model to F-T synthetic wastewaters at
Reason, it may include following steps：
S1, oil removing pretreatment is carried out to F-T synthetic wastewaters.
Generally, total oil content is higher in F-T synthetic wastewaters, about 332mg/L, in follow-up anaerobic bio-treated, oil
Part can wrap up microorganism floc sedimentation surface so that microorganism cannot absorb sufficient nutrition, influence the growth and breeding of microorganism, and then
Influence anaerobic bio-treated effect.Therefore, in order to ensure follow-up anaerobic bio-treated effect, it is necessary to useless to F-T synthesis in advance
Water carries out oil removal treatment.
In step S1, oil removing pretreatment is realized using pretreatment unit 10, wherein can be using filter paper filtering, fiber-ball filter media
Carry out oil removing one or more in the mode such as filtering and cocoanut active charcoal absorption.
F-T synthetic wastewaters are respectively adopted into filter paper filtering, fiber-ball filter media filtering and cocoanut active charcoal absorption to enter it
Row oil removal treatment, contrast is measured by the filtrate after filtering or adsorption treatment, is known individually using coconut activated by contrast
Charcoal adsorbs oil removal treatment, oil content clearance highest；Oil content clearance is reachable after adsorbing an adsorption treatment using cocoanut active charcoal
To 77.9%, oil content clearance can reach 86.9% after second adsorption treatment.Therefore, in the utility model, it is preferred to use coconut husk
Charcoal absorption carries out oil removing pretreatment to F-T synthetic wastewaters.
Certainly, can be also combined using in filter paper filtering, fiber-ball filter media filtering and cocoanut active charcoal absorption at least two
Oil removing pretreatment is carried out to F-T synthetic wastewaters, to remove or reduce the oil content in F-T synthetic wastewaters, is reached and is met anaerobism life
The requirement of thing treatment.
The pH value of S2, the regulation pretreated F-T synthetic wastewaters of oil removing, improves the pH value of F-T synthetic wastewaters.The step is led to
Toning regulating device 20 is realized.
Generally, the pH value of F-T synthetic wastewaters is relatively low, is 3 or so, it is impossible to directly carry out follow-up anaerobic bio-treated, because
For in acid condition, anaerobe particularly methanogen, very sensitive to pH, growth will be suppressed.Therefore, pass through
Alkali is added toward F-T synthetic wastewaters to adjust the pH value of F-T synthetic wastewaters.Therefore, in step S2, can be by NaOH and hydrogen
In at least one of calcium oxide input pretreated F-T synthetic wastewaters of oil removing, the pH value of F-T synthetic wastewaters is improved.According to pH
Improve effect, it is preferred to use NaOH adjusts the pH value of F-T synthetic wastewaters for target alkali.
Optimum pH (6.5-8.2) according to anaerobe body growth, by adding alkali by the pH of F-T synthetic wastewaters
It is worth regulation to 4.6-8.2, within this range, it is ensured that follow-up anaerobic reaction can be normally carried out.With reference to alkali consumption and cost,
The pH value of F-T synthetic wastewaters is adjusted to 4.6, under this pH value, it is ensured that follow-up anaerobic reaction can be normally carried out while significantly
Reduce alkali consumption, reduces cost.
In addition, in step S2, the pH value of F-T synthetic wastewaters is adjusted by adding alkali, can control follow-up anti-into anaerobism
Answer the water inlet pH value of device.
S3, addition nitrogen and phosphorus source, anaerobic bio-treated is carried out by the F-T synthetic wastewaters adjusted after pH value.Anaerobic organism
Treatment is carried out in anaerobic reaction device 30.
During anaerobic bio-treated, the organic matter in waste water under the collective effect of a large amount of microorganisms, by hydrolysis
Acidifying, hydrogenesis and acetogenesis and methane phase three phases, are eventually converted into methane, carbon dioxide and water, sometimes with a small amount of sulphur
Change hydrogen and ammonia.In general, in hydrolysis and souring stage, the BOD value changes in waste water are not obvious.Only in the methane phase stage, by
It is many with C0 in the organic carbon for constituting BOD2And CH4Form effusion, organic matter degraded, COD the and BOD values in waste water are obvious
Reduce.
In step S3, the preferred temperature of anaerobic bio-treated is 35-38 DEG C, in heat-treated under medium temperature.It is relatively low for temperature
Environment (such as winter), then can improve anaerobic bio-treated temperature by mode of heating, reach 35-38 DEG C.Improve anaerobism life
Thing treatment temperature can be realized by the heater of anaerobic reaction device 30.
During anaerobic bio-treated, can be low according to the water quality characteristic of F-T synthetic wastewaters, COD high, heavy metal, nitrogen and phosphorus content
Feature, mixing addition sanitary sewage carries out anaerobic bio-treated.
In step S3, nitrogen and phosphorus source can be by one or more offer in sanitary sewage, urea and dipotassium hydrogen phosphate.
In this regard, step S3 further may include：
S3.1, past F-T synthetic wastewaters mixing add sanitary sewage, urea and/or dipotassium hydrogen phosphate, there is provided the nutrition such as nitrogen phosphorus
Source.
Wherein, it is preferred to use sanitary sewage provides the volume ratio of the nutrient sources such as nitrogen phosphorus, sanitary sewage and F-T synthetic wastewaters
It is 3:7.In the case of the nutrient sources such as the nitrogen phosphorus that sanitary sewage is provided deficiency, urea and/or dipotassium hydrogen phosphate can be added.
S3.2, the mixed F-T synthetic wastewaters of step S3.1 are pumped into anaerobic reactor carry out anaerobic reaction.
In step S3, using sanitary sewage for the anaerobic bio-treated of F-T synthetic wastewaters provides nitrogen and phosphorus source, at place
Also process sanitary sewage while reason F-T synthetic wastewaters, can save the construction of domestic sewage processing system, save floor space,
Investment and nitrogen phosphorus medicament expense etc..
To reduce alkali consumption, reduces cost, by cultivating domestication anaerobe characteristic, acquires anaerobism and gives birth to by experiment
Optimal pH is value 4.6 in thing processing procedure, therefore, can entrance anaerobic reactor water inlet pH value (through the F-T in after step 2
Synthetic wastewater or be mixed with sanitary sewage F-T synthetic wastewaters pH value) be adjusted to 4.6.It is 4.6 for water inlet pH value, passes through
After anaerobic reaction, the water outlet pH value of anaerobic reactor can be 7 or so, and COD concentration and COD go in the waste water after anaerobic bio-treated
Except rate is in zone of reasonableness.
According to disposition, step S3 may also include：
S3.3, toward activated carbon is added in F-T synthetic wastewaters, for anaerobe provides skeleton, adhere to anaerobe
Growth, forms cenobium, and so as to be greatly improved anaerobism efficiency, COD clearances can be improved to 85% by 60%.
In addition, in the anaerobic bio-treated of step S3, may also include and collect the biogas that anaerobic reaction is produced.Biogas can be with
Recycle, for generating electricity or heat production, produce certain economic benefit.
Anaerobic bio-treated can improve the biodegradability of waste water, mitigate the treatment load of subsequent technique.
Embodiment of the present utility model is the foregoing is only, the scope of the claims of the present utility model is not thereby limited, it is every
The equivalent structure or equivalent flow conversion made using the utility model specification and accompanying drawing content, or be directly or indirectly used in
Other related technical fields, are similarly included in scope of patent protection of the present utility model.
