A nanophotonic scale inhibitor includes a silicon quantum dot core having a functionalized surface including a plurality of carboxyl groups, sulfonate groups, or phosphonate groups. A method for synthesizing a nanophotonic scale inhibitor material includes preparing silicon quantum dots for surface functionalization and functionalizing surfaces of the silicon quantum dots with one of a carboxyl group, sulfonate group, and phosphonate group. A method of inhibiting and monitoring scale formation in water systems includes providing the nanophotonic scale inhibitor to the water in the water system and visualizing scale formation by detecting fluorescence of the nanotphotonic scale inhibitor.

Disclosed herein is an intelligent wastewater purification and treatment device. The device comprises a drum, a plurality of protrusions arranged in an array are fixed to an inner surface of the drum, an oil scraping assembly is arranged in the drum, mixed oil adhering to the inner surface of the drum is scraped away by the oil scraping assembly, a bottom of the oil scraping assembly is provided with an oil conveying assembly, and the scraped mixed oil is discharged from the drum via the oil conveying assembly. One side of the oil conveying assembly is provided with a separation assembly, the separation assembly comprises a refrigeration tank and a separation portion, an oil outlet of the oil conveying assembly is fixedly communicated with the refrigeration tank via a discharge pipe, and the mixed oil entering the refrigeration tank is separated by the separation portion.

The invention discloses a device for in-situ sludge solidification and a comprehensive solidification method, which include a main control transmission chamber, an upward floating drive-curing device, a deep bi-directional cutting and curing device, a control end, external grouting pipe, a grouting source, and a slurry pump. The solidification device is characterized by high efficiency and the fact that it does not require additional equipment or methods. The solidification method enables various forms of deep, shallow, and combined deep-shallow in-situ solidification based on the field conditions of the sludge. This device and method address several issues with existing in-situ sludge solidification technologies, which are typically limited to shallow solidification, struggle to independently support deep and thick sludge areas after solidification, exhibit low efficiency, uneven solidification, and often require the use of additional equipment and processes. This invention allows for rapid and efficient large-area in-situ solidification of sludge.
