Embodiment 1

[0021] The sewage detection method provided by the present invention includes the following steps:

[0022] (1): Fix the sampler at the place of sewage discharge at 1m underwater for 10 days, then retract the sampler, extract part of the sewage sample with dichloromethane, then dissolve it with DMSO, and put it in the cold box at low temperature Save, and then pass part of the sewage samples through the DXY-2 biotoxicity tester or SHG-1 bioluminescence tester to perform the luminescent bacteria toxicity test on the sewage samples;

[0023] (2): If the luminous bacteria toxicity test in step (1) does not detect that the sewage is toxic, the sewage can be directly recycled and reused;

[0024] (3): If step (1) photobacteria toxicity test detects that the sewage is toxic, spray sewage treatment agent uniformly at the sewage outlet and fill the sewage sample into the plastic of the tetrafluoroethylene liner at a position downstream of the sewage outlet In the bottle, after filtering, th...

Embodiment 2

[0027] The sewage detection method provided by the present invention includes the following steps:

[0028] (1): Fix the sampler at the place of sewage discharge at 1m underwater for 10 days, then retract the sampler, extract part of the sewage sample with dichloromethane, then dissolve it with DMSO, and put it in the cold box at low temperature Save, and then pass part of the sewage samples through the DXY-2 biotoxicity tester or SHG-1 bioluminescence tester to perform the luminescent bacteria toxicity test on the sewage samples;

[0029] (2): If the luminous bacteria toxicity test in step (1) does not detect that the sewage is toxic, the sewage can be directly recycled and reused;

[0030] (3): If step (1) photobacteria toxicity test detects that the sewage is toxic, spray sewage treatment agent uniformly at the sewage outlet and fill the sewage sample into the plastic of the tetrafluoroethylene liner at a position downstream of the sewage outlet In the bottle, after filtering, th...

Embodiment 3

[0033] The sewage detection method provided by the present invention includes the following steps:

[0034] (1): Fix the sampler at the place of sewage discharge at 1m underwater for 10 days, then retract the sampler, extract part of the sewage sample with dichloromethane, then dissolve it with DMSO, and put it in the cold box at low temperature Save, and then pass part of the sewage samples through the DXY-2 biotoxicity tester or SHG-1 bioluminescence tester to perform the luminescent bacteria toxicity test on the sewage samples;

[0035] (2): If the luminous bacteria toxicity test in step (1) does not detect that the sewage is toxic, the sewage can be directly recycled and reused;

[0036] (3): If step (1) photobacteria toxicity test detects that the sewage is toxic, spray sewage treatment agent uniformly at the sewage outlet and fill the sewage sample into the plastic of the tetrafluoroethylene liner at a position downstream of the sewage outlet In the bottle, after filtering, th...

Abstract

The invention relates to a sewage detecting method comprising: sampling a sewage sample at a sewage discharge place, carrying out extraction on one part of sewage sample by using dichloromethane, carrying out dissolving by using DMSO, placing the processed sample in a refrigerator and storing the sample at a low temperature, and detecting the sewage sample by using luminescent bacteria toxicity testing; recycling and reusing the sewage directly under the condition of not detecting the toxicity in the sewage; spraying a sewage treatment agent uniformly at a sewage outlet and carrying out sampling detection again under the condition of detecting the toxicity in the sewage; and carrying out deep detection on the sewage sample placed in the refrigerator under the condition of detecting the toxicity in the sewage; and recycling and reusing the sewage directly under the condition of not detecting the toxicity in the sewage. Therefore, the sewage dosage can be evaluated preliminary from the perspective of toxicity; and secondary evaluation is performed after preliminary treatment against toxicity, so that the efficiency of sewage recovery is improved.

Description

Technical field [0001] The invention belongs to the technical field of sewage detection, and specifically relates to a sewage detection method. Background technique [0002] Domestic sewage is the waste water discharged in the daily life of residents. It mainly comes from residential buildings and public buildings, such as houses, offices, schools, hospitals, shops, public places and industrial enterprises toilets. The main pollutants contained in domestic sewage are organic matter (such as protein, carbohydrate, fat, urea, ammonia nitrogen, etc.) and a large number of pathogenic microorganisms (such as parasite eggs and intestinal infectious viruses, etc.). The organic matter in domestic sewage is extremely unstable and easily decomposes to produce foul smell. Bacteria and pathogens multiply by taking organic matter in domestic sewage as nutrients, which can lead to the spread of infectious diseases. Therefore, domestic sewage must be treated before it is discharged. [0003] A...
