Art scheme carry out it is described further below, but it is not intended that to the present invention can practical range restriction.
Embodiment
The present embodiment provides a kind of using characteristic contamination Source Tracing as the sewage disposal appraisal procedure instructed, certain stone is chosen
Acrylic fiber chemical factory of change company waste water processes, comprise the following steps (flow chart is as shown in Figure 1)：
Step 1, along sewage treatment process, respectively to the pollutional load situation of each technique unit, dirt in technological process
The energy consumption level of dye thing removal efficiency, the pollutant removal cost of unit mass and each technique unit is analyzed, and is combined
COD, BOD, TOC, ammonia nitrogen and TN macroscopic view Testing index are analyzed, and are judged each technique unit operation conditions, are primarily determined that operation
The technique unit that efficiency is relatively low, operation conditions is poor, forms and the preliminary of integrated artistic operation conditions is judged.
Step 2, with reference to the operation conditions of each technique unit of sewage treatment plant, takes the Inlet and outlet water of each technique unit
Sample, and the pretreatment of Solid Phase Extraction is carried out to water sample.
Step 3, using high performance liquid chromatography-electric field Orbitrap mass equipment to sewage disposal plant process flow end
Water quality is analyzed, and determines to remain in the organic matter composition in sewage after the processing of each technique unit, and definite wherein right
COD, BOD, DOM and TOC organic matter macro-indicators contribute most 5-8 category feature pollutants.
Step 4, traces to the source as a result, establish characteristic organic pollutants fingerprint databases according to characteristic contamination detection, clearly special
The collection of illustrative plates feature and identification main points of pollutant are levied, establishes characteristic contamination identification flow and method.
Step 5, using characteristic contamination collection of illustrative plates as guidance, to sewage disposal plant process flow from the front to the back to each technique list
The water quality of the Inlet and outlet water of member is analyzed, and determines source and the removal efficiency of each characteristic contamination, and tracks the centre of its degraded
Product and final product, determine selectivity and otherness that its degradation pathway and various treatment process remove it；Emphasis is to step
The technique unit that operational efficiency is relatively low in rapid one, operation conditions is poor is assessed, and determines to influence the key factor of its efficiency, and
And determine the critical process unit of effect characteristics pollutant removal.
Step 6, optimizes for critical process unit and key factor, so as to fulfill full process stream journey optimization and
Assessment.
In August, 2015-October, certain acrylic fiber chemical factory of petro-chemical corporation sewage disposal is completed using the above method of the present embodiment
Flow path efficiency assess, to the bio anaerobic of the sewage-treatment plant, biology aerobic, chemical oxidation, biological fluidized bed, nitrification tank,
The cell process such as charcoal tower have carried out characteristic contamination Source Tracing and degradation pathway analysis.
Through analysis, it is to influence sewage treatment plant's stable operation and upgrade crucial source up to standard to determine factory's acrylonitrile sewage

Characteristic contamination, is a series of key factor for influencing biochemical treatment facility operations.In addition, exist to above-mentioned a few category feature pollutants
Being analyzed along journey degradative pathway in sewage disposal process, it is determined that chemical oxidation unit, organism fluidization bed unit are being selected
Selecting property degraded characteristic organic compound, improve Biodegradability of Wastewater, reduce the efficiency of subsequent cell pollutional load etc., and determines
The maximum efficiency of each unit technique under different substrates concentration.
The parameters such as the ORP and DO of anaerobic pond found during combined process effect preliminary assessment are higher, organism fluidization pond and nitre
The problems such as function in change pond is overlapping, has researched and proposed targetedly process optimization scheme, to during acrylonitrile mass degradation
The anaerobic pond service condition to play a significant role is regulated and controled, and strictly controls anaerobic pond DO in 0.1~0.25mg/, ORP value control
System anaerobic pond water outlet B/C after -250~-100mv, adjustment is improved to 0.21~0.26 by 0.12~0.18, is follow-up technique
Section further removes pollutant and creates advantage.It is up to that 6.5~8.0mg/L, sludge concentration be low, nitre for DO in nitrification tank
Change the problems such as reaction efficiency is low, controlled by operating condition, DO is adjusted to 1.5~2.5mg/L, hydraulic detention time and is down to 8
~10h, sludge concentration is improved to 2800~3100mg/L, nitric efficiency by 600~700mg/L in pond dramatically increases.
It is made up of and analyzes pollutant, the feature for restricting sewage treating efficiency lifting and outer draining stably reaching standard pollutes
Amide substance in thing, mainly acrylonitrile sewage, to realize that the targeting of characteristic contamination removes, to a variety of chemical oxidation skills
Art carries out preferably, using evaluation criterion of the amide substance degradation efficiency as chemical oxidation process, determining to use the micro- electricity of iron carbon
Pretreatment unit of the integrated technique of solution-Fenton oxidation as biochemical advanced treating.Using sideline test mode, to above-mentioned multiple
Close oxidation technology efficiency and verified that result of the test shows, when TOC of intaking is 760~820mg/L, composite oxidation technology
TOC of yielding water can be down to below 300mg/L, and amide substance removal rate is up to 53~66%, CN- in subsequent bio fluid bed water outlet
(characteristic ion of acrylonitrile material) concentration reduces amplitude up to 40%~55%, and COD is by 170mg/L for integrated artistic least significant end water outlet
90~110mg/L is down to above, has reached expected purpose.
