The invention discloses a method for detecting the refilling residual oil quantity of a mineral oil transformer. The method comprises the following steps: cleaning residual mineral oil in the mineral oil transformer through at least three stages of specific cleaning processes, filling natural ester insulating oil, sampling, and detecting the mineral oil content in sample oil by adopting gas chromatography-tandem mass spectrometry; according to the present invention, the residual mineral oil at the difficult-to-clean part is completely adsorbed and eluted by precisely controlling the cleaning process parameters so as to substantially reduce the residual amount of the mineral oil in the transformer, and the gas chromatography-tandem mass spectrometry multi-mode detection method is matched with the refilling process so as to achieve the precise detection of the mineral oil content in the insulating oil sample, the recognition sensitivity of trace mineral oil residues is remarkably improved, and accurate and quantitative refilling is realized; according to the method, the advantages of process collaboration and integration are utilized, the operation performance of the refilled transformer is remarkably improved, the risk of insulation performance reduction caused by oil degradation is effectively inhibited, and the long-term stable operation life of the transformer is prolonged.

The application discloses a treatment method for removing fluorine and improving quality of high-fluorine hot spring water while retaining beneficial trace mineral elements. After adding a proper amount of active magnesium oxide powder to high-fluorine hot spring water, the fluorine ions in the high-fluorine hot spring water are effectively removed through oscillation adsorption, the fluorine content in the high-fluorine hot spring water is reduced to below the limited value of the national standard GB8537-2008 of mineral water, the beneficial trace mineral elements in the hot spring water are effectively retained, the total hardness concentration of the hot spring water is lower than the recommended value (18.70mg / L<150mg / L) of the World Health Organization for magnesium in drinking water, namely, the drinking water treated by the method meets the national drinking water standard. The raw material is easy to obtain, the adsorption material is simple to prepare, low in cost and convenient to use, and is suitable for promotion.

The application provides a multi-layer mineralized filtering water cup, which comprises a cup body and a cup cover, a flip cover is hinged to the cup cover, a filtering drinking water part is arranged on the flip cover, a water guide hole is arranged on the cup cover, the filtering drinking water part is movably arranged in the water guide hole, and a pp cotton layer, an activated carbon layer, a medical stone mineralization layer and an ultrafiltration membrane layer are sequentially arranged along the water flow direction of the filtering drinking water part. The application can realize precise filtering, display the water quality safety grade in real time, dynamically calculate the filter screen life, adapt the mineral release amount to the water temperature change, connect the APP end through the Bluetooth module to record the drinking water data and push the filter screen replacement reminder, and has the drinking water effect of being suitable for drinking high-quality drinking water and supplementing the human body with essential trace minerals, so that the user can drink comfortably and healthily, the use is convenient, and the application is more comprehensive.
