Problems solved by technology

However, the above-mentioned COD detector still has certain defects: there are still many processes in the entire detection process that need to be manually operated, and the degree of automation is not high; when sampling is performed manually, it is easy to cause inaccurate sampling, thus Affects the measurement results; in addition, when cooling, it is necessary to pass cooling water into the cooling tank for cooling, so a large amount of cooling water is required, and the energy consumption is high

Embodiment Construction

[0024] The following examples can enable those skilled in the art to understand the present invention more comprehensively, but the present invention is not limited to the scope of the described examples.

[0025] Such as figure 1 The full-automatic COD analyzer shown includes a heating unit, a condensation unit, a clamping unit, and a titration unit arranged in sequence. A liquid addition unit is arranged beside the heating unit and the condensation unit, and a liquid addition unit is arranged beside the condensation unit. There is an equipment self-test unit.

[0026] The heating unit includes an electrical control box 4, and a heating plate 2 connected thereto is installed on the upper end of the electrical control box 4. The heating plate 2 has several grooves 6 that are distributed in a matrix to accommodate sample cuvettes 5 to embed. The side end of the electrical control box 4 is also provided with a liquid storage tank 7 . Regarding the design of the heating unit, t...

Abstract

The invention relates to a full-automatic COD analysis meter. The full-automatic COD analysis meter comprises a heating unit, a condensation unit, a clamping unit and a titration unit which are arranged in sequence. A liquid adding unit is arranged beside the heating unit and the condensation unit. An automatic equipment testing unit is arranged beside the condensation unit. The full-automatic COD analysis meter has the advantages that due to the arrangement of the heating unit, the condensation unit, the clamping unit, the titration unit and the liquid adding unit, manual operations are reduced, and the automatic degree is high; in addition, due to the arrangement of the automatic equipment detection unit, automatic detection can be performed, and experiment data authenticity is ensured.

Description

technical field [0001] The invention relates to the field of water quality measurement, in particular to a fully automatic COD analyzer. Background technique [0002] COD is a commonly used comprehensive index to evaluate the degree of water pollution. It is the abbreviation of chemical oxygen demand in English, and its Chinese name is "chemical oxygen demand" or "chemical oxygen demand". The amount of oxygen consumed. It reflects the extent to which the water body is polluted by reducing substances. Since organic matter is the most common reducing substance in water, COD reflects the degree of water body pollution by organic matter to a certain extent. The higher the COD, the more serious the pollution. China's "Surface Water Environmental Quality Standards" stipulates that the COD concentration of drinking water sources should be less than 15 mg / L, and the COD concentration of general landscape water should be less than 40 mg / L. [0003] The COD detector is an essenti...
