The invention discloses a hydrophilic carrier for microbial biofilm formation. The hydrophilic carrier comprises a hollow short tube, and a first concentric ring and a second concentric ring which are sequentially concentrically arranged outside the hollow short tube, wherein the surface of the outermost second concentric ring is toothed; and the microbial filler is composed of the following components in parts by weight: high-density polyethylene, low-density polyethylene, white lime, Dow powder activated carbon, light calcium carbonate, maleic anhydride, dicumyl peroxide, gelatin, chitin, ferroferric oxide magnetic powder and manganese-zinc ferrite. The density of the microbial filler is 0.96-0.98 g / cm<3>. The hydrophilic carrier for microbial biofilm formation prolongs the contact time between microbes and organic matters, so that the organic matters are degraded quickly and thoroughly; and the biological oxidation can restore the surface adsorption capacity of the activated carbon.

The invention discloses a path planning method based on a mobile robot. The method comprises the steps that based on a polygonal barrier planar model, Q-IGA is utilized to collaboratively search for the most appropriate control point P which serves as a control point of a Bezier curve, and the control point is utilized to generate an optimal path; the difference between difference paths in a population in each iteration is calculated, a judgment criterion is added to a selection operator for optimization, and the diversity of feasible solutions in the population is guaranteed; and a fitness function considering a barrier distance, a turning angle and a robot volume is constructed with the optimization objective of a maximum fitness function value. Through the method, the situation that steps are tedious when the optimal path is obtained through direct fitting search by use of the Bezier curve in robot path planning is avoided, it is guaranteed that the path planning process is completed efficiently, consumed time is short, and path planning efficiency is higher.

The invention discloses an active encapsulation method which utilizes the spontaneous light of a chip to initiate photosensitive resin polymerization for the in-situ preparation of a lens with an LED single layer and multilayer structure. The method includes the following steps: photosensitive resin liquid wave band light which is sensitive to specific wave band light is prepared; an LED semi-finished product which is processed by electrode connection and die bond is presoaked in photosensitive resin for die bond; the LED semi-finished product is inverted to be soaked in the photosensitive resin liquid, low working current is led into and enables the LED chip to be luminous, photosensitive resin is triggered to generate preliminary polymerization, and a photosensitive resin core is formed on the luminous surface of the LED chip; the LED semi-finished product is separated from the surface of the photosensitive resin liquid, and the drops of the photosensitive resin liquid need to be attached to the photosensitive resin core and a chip base; the intermediate working current is led into and enables the LED chip to be luminous, and the drops of the photosensitive resin liquid are stimulated to be solidified; after the solidification of the drops of the photosensitive resin liquid, high working current is led into a sample so as to enable the LED chip to be luminous, and then the steps of solidification and decoloration are carried out, or the sample is irradiated by sunlight, purple light or ultraviolet light to be decolourized; and finally the sample processed by solidification and decoloration is cleaned.
