Loudi Sewage Treatment Plant Laboratory Construction Management

What are the requirements for laboratory construction of Loudi Sewage Treatment Plant?The editor of SICOLAB will tell you about it

I. Considerations for the construction of the laboratory of the sewage treatment plant

The site selection should focus on how to follow the principle of site selection and how to coordinate with the overall planning when selecting a site.Indicate the topography, geological conditions, land area, sanitary protection distance, etc. of the selected plant site.

1. The quality and quantity of sewage, including the values ​​of various indicators of sewage quality, the average flow of sewage, peak flow, current flow, and development waterEquivalent water data.

2. Selection and calculation of the technological process, mainly to explain the rationality, superiority and safety of the selected technological process.

3. Calculation of each treatment facility in the technological process, main dimensions, structure, material and characteristics of the treatment facility; additional equipment selectedmodel, performance and number of units.

4. The way out of the treated sewage and sludge.

II.Sewage treatment plant laboratory construction: sampleCollection and management of

Layout of sampling points for efficiency monitoring of sewage treatment facilities

1. When monitoring the efficiency of the overall sewage treatment facility, set sampling points at various inlets of sewage entering the sewage treatment facility and the total discharge of the sewage facility.

2. When monitoring the efficiency of each sewage treatment unit, set sampling points at the inlets of various sewage entering the treatment facility units and the discharge outlets of the facility units.

III.Sewage treatment plant laboratory construction:Management of the detection process

1. Quality assurance during inspection

1) Regularly use certified reference materials (samples) for intra-laboratory comparison a direct reading monitoring instrumentIn addition, certified reference materials should be used for comparison on a regular basis, and records should be made to ensure the accuracy of monitoring instruments.b In the method verification of the new project, the project with standard samples should be tested with certified standard samples, and the measurement results can be used as an important basis for evaluating the accuracy and precision of the project's experimental report.

2) When repeating inspections with the same or different methods for method validation of new monitoring items or improved monitoring methods, the same sample or standardSamples are tested repeatedly by the same or different methods, and a more scientific judgment can be made on the accuracy and precision of the method.

3) During the analysis process, standard substances can be added with batches to make the test data accurate and reliable.

2. Monitoring personnel fill in the quality control data report on time

After checking by relevant personnel, report to the person in charge for review.Quality control reports are filed together with monitoring original records.
