Abstract: Devices for controlling to remove food waste digestion foam are provided. The device includes a digestion tank. The digestion tank includes two hermetically sealed boxes. Each of the two boxes is opened with a liquid inlet connected to an interior of each of the two boxes. A conveying mechanism is connected between the two boxes. The conveying mechanism conveys a gas in the two boxes in a reciprocal manner. The gas in the two boxes is conveyed in the reciprocal manner through the conveying mechanism to generate a pressure difference between the two boxes distributed left and right to remove the foam, which adopts physical defoaming without adding any reagent, is cost-effective and efficient, and does not affect an anaerobic reaction process due to addition of a chemical defoaming agent. The entire device has a simple structure and is easy to operate, and the process is controllable.

Abstract: Embodiments of the present disclosure provide a device for kitchen waste digestion, including: a first treatment container, provided with a feed pipe and an exhaust pipe at a top, and internally configured with a plurality of pole plate pairs, the pole plate pairs including two pole plates, one of the pole plates being connected to a positive pole of a power source and another being connected to a negative pole of the power source, and a plurality of sieve holes being provided in each of the pole plates; and a second treatment container, a top of the second treatment container connecting to a bottom of the first treatment container, a middle part being configured with a plurality of filler layers spaced apart in a vertical direction, and a bottom being configured with an iron-carbon filler; and a filler in the filler layers including calcium peroxide and magnetite particles.

Abstract: The embodiments of the present disclosure provide a centralized treatment device for kitchen waste. The centralized treatment device includes an upper box, an outer cover, a pulverizer, an inner cover, a filter press, a drying granulator, a lower box, an electrolysis device, a hanging basket, a material box, an exhaust fan, and a linkage mechanism. Smashed kitchen waste is subjected to solid-liquid separation by the filter press. Filter residues enter the drying granulator to be partially carbonized, and partially carbonized filter residues and mixed powder treatment agent form solid residue particles. The solid residue particles degrade and adsorb pollutants in the water after being activated by an acidic solution. Meanwhile, accumulated water-absorbing solid residue particles help to degrade the pollutants in the water through the electrolysis device. A separation area is configured to separate oil and discharge the oil separately.

Abstract: The present invention relates to a ground double-hole combined water inrush prevention method for overlying strata movement monitoring and bed separation water drainage. By arranging a rock strata movement monitoring borehole and a bed separation water drainage borehole, interior movement information of an overlying stratum and bed separation generation timing fed back by strata movement monitoring performed inside are monitored; work on the bed separation water drainage borehole is guided by monitoring changes in arranged monitoring points; and through combination of the movement monitoring borehole and the bed separation water drainage borehole, the utilization rate of the bed separation water drainage borehole is effectively increased.
