Abstract: The present invention discloses a heavy metal treatment composite microbial agent in water and a preparation method thereof, belonging to the field of heavy metal treatment. The microbial agent of the present invention is prepared from the following components in parts by weight: 20-30 parts of Pseudomonas, 15-30 parts of Bacillus, 5-15 parts of Staphylococcus, and 5-15 parts of Pichia pastoris. The microbial agent of the present invention can quickly and efficiently adsorb and remove heavy metal ions, and the removal efficiencies of the microbial agent of the present invention on the cadmium, copper, lead and chromium after 2 d reach 81.0%, 56.5%, 52.0% and 74.0% respectively, wherein the adsorption and removal effects on the cadmium and chromium are most obvious.

Abstract: The present invention provides a control method for a smart light, comprising: displaying control information of connected smart lights as a first kind of icon and/or a second kind of icon on a main interface, the first kind of icon corresponds to a single light and the second kind of icon corresponds to a group consisting of at least two single lights; when detecting at the position of the first kind of icon and the second kind of icon and identifying as selected operation, displaying a control interface corresponding to the single light or the group; the control interface comprises a light-adjusting tab, the light-adjusting tab comprises a parameter adjustment column, a switch button and an effect simulation diagram; when the light-adjusting tab is on active page, sending parameter configuration information to corresponding single light or group based on sliding position of detected slider in the parameter adjustment column, and sending switch light configuration information to corresponding single light
