Problems solved by technology

This method is complex in operation, high in cost, and inconvenient to treat the sewage after detection. At the same time, air bubbles are likely to be generated in the process of sewage detection and reaction, which will have a certain impact on the results of sewage detection, and there are certain defects.

Embodiment 1

[0040]When the feed channel 5 is 1, the sample treatment of the sample to be drawn is removed, the sample chamber 4 is vacuum, rotates, or the position of the moving valve stem 6, opens the inventive passage of the valve cavity 3 and the sample cavity 4, will The sample was detected in the sample chamber 4, and then pushed the valve stem 6 or the rotary valve rod 6, the passage, the sample treatment test capsule was shaken under the action of the external vibration rod, so that the drug and the sample were mixed uniform, and finally the test capsule The horizontal is horizontally, and the air bubbles in the test capsule enters the gas chamber 13 horizontally to the measurement instrument for measurement of the sample absorbance.

Embodiment 2

[0042]When the feed channel 5 is 2, the sample treatment test capsule is taken out, first push or rotate the valve stem 6, and the annular feed tank on the valve stem 6 is located at one of the feeding passages opened by the side wall of the valve chamber 3. , Open the communication passage of the valve cavity 3 and the sample chamber 4, and then pull the sample chamber 4 into a vacuum, then push or rotate the valve stem 6, turn off the channel; then push the valve stem 6, open another feeding passage 5, so that the valve cavity 4 The communication passage of the sample chamber 3 is opened, and the sample to be detected is automatically inhaled into the sample chamber 4 by the feeding passage 5, and then pushes the valve stem 6 or the rotary valve rod 6, the passage, the sample treatment test capsule is shaking the vibration rod The drug is mixed with the sample, and finally the sample treatment test capsule is horizontally, so that the gas chamber 13 is upward, so that the air bubb...

Abstract

The invention discloses a sewage detection method and application, and is used in the field of sewage detection. The sewage detection method comprises the following steps that a colorimetric device for sewage detection is prepared, a cavity, used for loading a sample to be detected, of the device is vacuum, and a mechanism used for controlling opening and closing of a channel communicated with the cavity is arranged on the cavity; a detection reagent is preloaded in a cavity for loading a sample to be detected in the colorimetric device, or the detection reagent is preloaded in a channel communicated with the cavity; a channel communicated with the cavity is opened, the negative pressure environment in the cavity sucks the sewage sample into the cavity, the channel communicated with the cavity is closed, and the sewage sample and the detection reagent are sealed in the cavity; the vibrating rod is used for vibrating the colorimetric device so that a sewage sample and a detection reagent are uniformly mixed, and the device is used for detecting the absorbance of the sample. According to the method, sewage detection can be rapidly and conveniently realized, pollution of detected reagents to the environment is avoided, and meanwhile, accuracy of sewage detection can be greatly improved.

Description

Technical field[0001]The present invention relates to the field of sewage detection, and more particularly to a sewage detection method and use.Background technique[0002]Today, prior art in the mobile water analysis is represented by the "Photometric Cuvette Tests) disclosed in DE 4109118 A1. The use of these test facilities is done by manual operation. First, the water sample is taken with a pipette and the water sample is supplied into a test tube containing a master reagent. The test tube is closed and allowed to mix the water sample and the primary reagent, followed by insertion of the test tube into the photometric meter and measure the sample. This manual test tube test is not convenient and is very easy to have error. The used primary reagent will hazard for health and the environment, so the test tube must be treated accordingly after the analysis. This method is complicated, high cost, and the sewage treatment after the detection is inconvenient. At the same time, it is pro...
