Abstract: A method, device, system, and storage medium for tracking a moving target are provided. The method uses three-dimensional radar observation data to construct a state vector and a motion model of the moving target, thereby to construct a state equation and an observation equation for achieving filtering and tracking within a linear Gaussian framework. The disclosure is also suitable for a moving target in a two-dimensional scene with a distance and an azimuth, and the disclosure use a two-dimensional observation vector to construct a dynamic system to achieving tracking of the moving target. The disclosure can be used in radar systems containing Doppler measurements, and tracking of moving targets can be implemented by performing dimension-expansion processing on observation equations.

Abstract: A method and apparatus for removing pollutants from organic solid waste by pyrolysis coupled with chemical looping combustion are provided. The apparatus includes: an air reactor, a fuel reactor, and a pyrolysis gasifier. The pyrolysis gasifier is sleeved outside the fuel reactor, and the air reactor is connected with the fuel reactor. A top end of the air reactor is connected with a top delivery pipe; the top delivery pipe is connected with a first cyclone separator; and the first cyclone separator is connected with an oxygen carrier refeeder provided at a top end of the fuel reactor. The apparatus forms a two-stage reaction unit of pyrolysis and chemical looping combustion by decoupling the pyrolysis process from the chemical looping combustion, which avoids the contact between the complex ash of organic solid waste and the oxygen carrier, thereby improving the service life of the oxygen carrier.

Abstract: A container-type apparatus for wastewater treatment with a suspended particle system, including one or multiple biological reaction zones. The biological reaction zones can be facultative, anaerobic, anoxic, and aerobic and at least one of the biological reaction zones is a suspended particle system. Particles in the suspended particle system act as the carrier of microbiota and offer better conditions for them to grow. The apparatus adopts a box structure, such as a container type, which is convenient to move, flexible to assemble, and can be used multiple times. Based on actual requirements, this apparatus can also be a structure type. The suspended particle system can increase the concentration of microorganisms significantly, improve the ability to bear impact load, produce less sludge, and without sludge expansion.

Abstract: The present disclosure discloses a slightly heavy particle system for wastewater treatment, comprising a contactor. Said contactor includes a gas-liquid-solid three-phase region, and said gas-liquid-solid three-phase region includes gas phase, liquid phase, and solid phase. Said liquid phase is the continuous phase and said solid phase is slightly heavy particles. Said slightly heavy particles are able to carry some microorganisms on their surfaces at least, and the density of said slightly heavy particles is higher than the density of said liquid. The slightly heavy particle system of the present disclosure applied in wastewater treatment can increase the concentration of microorganisms significantly, improve the ability to bear impact load, produce less sludge, and without sludge expansion. Meanwhile, the means to suspend slightly heavy particles with the combined effect of gas and liquid is able to reduce energy consumption to a larger extent.

Abstract: A method for purification and conditioning of crude syngas based on properties of molten salts, includes removing particles at a high-temperature by enabling the high-temperature crude syngas produced by a gasification device to firstly pass through a high-temperature particle removal device to remove solid particles in the gas; removing hydrocarbons in the presence of oxygen by introducing an oxidant into the crude syngas after treatment, selectively removing the hydrocarbons in the crude syngas and simultaneously utilizing high temperature produced by oxidation of the hydrocarbons to crack tar; and removing gas pollutants and conditioning by introducing the obtained crude syngas into molten salts medium, removing pollutants containing sulfur and chlorine in the crude syngas, and simultaneously adjusting the H2/CO ratio of the syngas to obtain purified syngas.
