Problems solved by technology

However, the online automatic monitoring equipment still has the disadvantages of high price, poor stability and monthly calibration. Installing equipment at each sewage outlet will undoubtedly require a lot of cost investment, and the later maintenance workload will be large
In addition, if the equipment is damaged by man-made changes, or there are hidden sewage outlets, it is necessary to use ordinary pollutant traceability technology to trace the source, which still faces the problem of heavy workload, time-consuming and labor-intensive

Embodiment 1

[0047] After investigation, a representative manufacturer A of food production in the upper reaches of the North Canal in Huo County, Tongzhou, produces soybean paste, soy sauce, vinegar and other condiments. Collect the production sewage and waste water of manufacturer A, fill the sampling bottle with water samples without leaving space and air bubbles, affix a label and seal the mouth of the sampling bottle with sealing tape. The water samples were transported back to the laboratory on the same day and stored in a refrigerator at 4°C. The analysis and screening of anion species, organic species, metal elements and fluorescence information are carried out as follows:

[0048] Analysis and screening of anion type information: Take 20ml of water sample for vacuum filtration, dilute the filtrate 10 times with ultrapure water, and pass it through a 0.22μm microfiltration membrane for ion chromatography analysis. The conditions of ion chromatography are as follows: Dianne ICS-9000...

Embodiment 2

[0059] After investigation, the representative manufacturer B in the upper reaches of the North Canal in Huo County, Tongzhou, produces cooked duck food, hot pot bottom material, etc. Collect the production wastewater of manufacturer B, fill the sampling bottle with water sample without leaving space and air bubbles, label it and seal the mouth of the sampling bottle with sealing tape. The water samples were transported back to the laboratory on the same day and stored in a refrigerator at 4°C. The fingerprint information of the water sample is detected, extracted, analyzed and sorted, and the process and method are the same as in Example 1.

[0060] The sewage fingerprint obtained from manufacturer B is: anions include fluoride ion and phosphate ion; organic matter contains m-cresol, natural capsaicin, 2,4-di-tert-butylphenol, skatole, erucamide, oleic acid amide; characteristic metal The elements are Ti and Cr, and the corresponding concentrations are 4.31ppm and 0.15ppm; t...

Embodiment 3

[0065] After investigation, the representative manufacturer C of the chemical industry in the upper reaches of the North Canal in Huo County, Tongzhou, the product is polyacrylamide. Collect the production sewage and waste water of manufacturer C, fill the sampling bottle with water samples without leaving space and air bubbles, label and seal the mouth of the sampling bottle with sealing tape. The water samples were transported back to the laboratory on the same day and stored in a refrigerator at 4°C. The fingerprint information of the water sample is detected, extracted, analyzed and sorted, and the process and method are the same as in Example 1.

[0066] The sewage fingerprint obtained from manufacturer C is as follows: anions include fluoride, chlorite, chlorate, and bromate; organic matter acrylamide, 4-methoxyphenol, erucamide, oleamide, and methyl hexadecanoate; The metal elements are Cr and Ag, and the corresponding concentrations are 0.10ppm and 0.07ppm; the fluore...

Abstract

The invention relates to a method for rapidly tracing to a water pollution source of a water area (comprising a river, a lake, a reservoir and the like) so as to strengthen the pollution discharge supervision, namely a method for rapidly tracing to a pollution source in a water area by establishing a chemical fingerprint information database in an upstream of the water area and around the pollution source. According to the method provided by the invention, the water pollution source is rapidly traced by analyzing pollution discharge information of pollution discharge enterprises in the upstream, and establishing the sewage chemical fingerprint database of the enterprises in advance. Compared with the conventional water pollution source tracing method, the method can be used for greatly reducing a quantity of water samples in need of being detected and analyzed, so that the method is rapider, effective and standard, and has more powerful supervision strength. Compared with the existing pollution discharge supervision technology, the method can be used for greatly reducing the mounting and using quantity of online monitoring equipment and saving a large amount of cost, is more economical and convenient, is easier to maintain and update, and is more effective and standard.

Description

【Technical field】 [0001] The invention belongs to the technical field of water pollution source traceability and enterprise sewage discharge supervision. Specifically, the invention relates to a method for quickly realizing water pollution traceability to strengthen sewage discharge supervision. 【Background technique】 [0002] The problem of illegal illegal discharge of excess sewage is more serious in our country, which has caused serious pollution and damage to the water system and ecological environment. It is a very arduous task to strengthen the effective supervision, traceability and accountability of pollutants that exceed the standard of illegal sewage discharge. Among them, the investigation of pollution sources and the traceability of pollutants are indispensable links. Only when the source of pollution is well traced can the source of pollution be cut off in time to prevent further deterioration of the pollution situation; only when the source of pollution is wel...
