The invention discloses a high-steep rocky hill vegetation recovering construct and a plantation recovering method thereof. The construct includes an earthwork standard room and a three-dimensional metal net, wherein the earthwork standard room is located on the upper layer of a rocky hill, and the three-dimensional metal net is located on the upper layer of the earthwork standard room; space formed by the earthwork standard room and the three-dimensional metal net is filled with manmade soil and three-dimensional multi-layer vegetation which is located on the upper layer of the manmade soil. According to the plantation recovering method, through the earthwork standard room, the three-dimensional metal net and the manmade soil forms an integral wholeand are both independent units, and the three-dimensional metal net and the manmade soil have not only relations but also differences. On the surface, the construct is a whole of which the structure is very firm and stable, but the bottom earthwork standard room divides the whole into cells. Cell rooms are communicated with one another, and through root growth of plants, a uniform and organic rock-soil-microorganism-vegetation system is formed.

By means of the system, the recovery of vapour discharging workingmediums and heat of the flash tank can be achieved, and the purpose of eliminating white smoke plume can be achieved.

The invention belongs to the technical field of preparation products for daily appliances, and particularly relates to an effective toilet-cleaning foam aerosol and a preparation method thereof. The foam aerosol comprises, by weight, 8-18% of a propellant, 5-10% of a foaming agent, 2-8% of a deodorizing agent, 0.1-0.6% of a thickener, 0.3-0.6% of natural bio-antimicrobial agents, 0.2-0.4% of preservatives, 0.2-0.4% of essences, and 62-84.2% of deionized water. The effective toilet-cleaning foam aerosol has the advantages of effectively removing and isolating foul smell, having fine and rich foams, keeping stable for a long time, resisting to water splashing, cleaning toilets with toilet paper saved, being environmental friendly and water saving and the like.

The invention relates to the technical field of medical containers for wards, in particular to a sputum container used in a ward to prevent the spread of germs. A guiding mechanism is arranged in connection, and the guiding mechanism is located below the corresponding opening; a transmission mechanism is arranged under the guiding mechanism, and a storage mechanism is arranged under the transmission mechanism; After converging in the middle, they are guided to the transmission mechanism by the guide mechanism, and enter into the storage mechanism by the transmission mechanism; a disinfection mechanism is arranged above the guide mechanism. The device can seal and store the sputum, preventing the spread of germs in the sputum.

The invention discloses a production method of super-imitation cotton fabric using waste polyester bottles. The method includes classifying the waste polyester bottles, and subjecting recycled polyester with intrinsic viscosity of less than 0.63g / dl to alcoholysis and esterification to obtain copolyester with a good hydrolytic function; subjecting recycled polyester with intrinsic viscosity of greater than 0.63g / dl and the copolyester to blending, fusion and spinning to obtain blend fibers; spinning the blend fibers to obtain fabric, performing treatment with dilute alkali solution to remove material C before drying, and subjecting the dried fabric in impregnating solution composed of polyethylene glycol monoester maleate and potassium persulfate to immersion treatment to obtain novel polyester fabric with super-imitation-cotton performance. According to the method, the waste plastic bottles are utilized to prepare the novel super-imitation cotton fabric, thus visual pollution can be avoided, resources can be recycled, pollution can be reduced, burden on municipal solid waste disposal can be relieved, land consumption can be saved , and good economic benefits can be achieved.

The invention relates to a parking management system for shared bicycles. The parking management system for shared bicycles includes a parking unit arranged on the ground and an identification unit installed on the vehicle body; the parking unit includes a group of matching emission posts and receiving posts , a light emitter is installed on the side wall of the emitting column, and a light receiver is installed on the side wall of the receiving column; the light emitter and the light receiver face each other and are powered by a power supply; The system is wirelessly connected; the identification unit includes an information converter for processing optical signals, and the level of the information converter is the same as that of the light transmitter and light receiver; the system can effectively simplify the structure of the parking area , reduce operating costs, standardize the parking arrangement, beautify the street environment, improve the car return experience, and facilitate parking for users; at the same time, provide larger storage space to facilitate the use of peak traffic.

The invention proposes a method for comprehensive utilization of heat energy in a multi-hearth furnace sludge pyrolysis system, which includes the following steps: the tail gas of the pyrolysis process is mixed with the secondary air sent by the blower in the secondary furnace and fully burned, and finally produces a small amount of dust The high-temperature flue gas with similar pollutants and trace acidic gas components enters the waste heat steam boiler, and then produces medium-pressure superheated steam, which is sent to the mud cake delivery pump group at the front end of the pyrolysis process and the main induced draft fan at the end of the pyrolysis process for Directly drives the mud cake conveying pump set and the steam turbine in the main induced draft fan at the end of the process. The invention adopts the waste heat steam boiler to recover and utilize the thermal energy of pyrolysis process tail gas and high-temperature flue gas, and the superheated medium-pressure steam produced is cascadedly applied to the steam turbine driving medium of high-power electrical appliances and the heat source medium of the sludge supplementary drying device , The thermal insulation / heating medium of the raw sludge storage bin, the liquid preparation / washing water (hot water) of the scrubber, improve the comprehensive utilization efficiency of flue gas heat energy.
