Abstract: The present invention relates to a macro plastic and micro plastic detection method based on RGB and hyperspectral image fusion, which includes the following steps: obtaining macro plastics and micro plastics; mixing with solid wastes to obtain a solid-phase substrate; pretreating the obtained solid-phase substrate to obtain a material; drying to remove part of moisture and coating on a quartz window sheet, drying until the moisture is completely removed, and flattening by using another quartz window sheet to obtain a material to be detected; obtaining an RGB image and a hyperspectral image of the material to be detected respectively by using a high-resolution color image scanner and a hyperspectral camera; fusing the obtained RGB image and hyperspectral image; and automatically classifying and identifying the macro plastics and the micro plastics by using a supervised classification model.

Abstract: Provided are an anaerobic immobilized bacterial agent, a preparation method for same, and applications thereof. The preparation method for the bacterial agent is: selecting four different anaerobic functional bacterial strains, utilizing a pure bacteria culturing technique to produce corresponding culture broths, then mixing the four culture broths according to a certain volume ratio to acquire a compound functional broth, subsequently concentrating into a functional flora precipitation, then dissolving the functional flora precipitation into a polyvinyl alcohol aqueous solution, dripping the solution into a first buffer solution to produce polyvinyl alcohol gel beads, and placing the gel beads produced into a second sulfate-containing buffer solution to produce sulfate-modified polyvinyl alcohol gel beads, that is, the anaerobic immobilized bacterial agent.

Abstract: A method for removing calcium ions from high concentration organic wastewater is provided. The method comprises the steps of: (1) introducing high concentration organic wastewater containing Ca2+, inorganic carbon and a seed crystal into a reactor with a molar ratio of Ca2+ to inorganic carbon of 1:(3.2-6.2); (2) adjusting the hydrogen ion activity ?(H+) and ionic strength of the solution in the reactor; (3) sequentially stirring and precipitating in the reactor to convert Ca2+ in the high concentration organic wastewater into calcium carbonate which is then precipitated for calcium removal.

Abstract: The present invention relates to a self-deodorizing composting system, comprising an outer membrane, an inner membrane, an air-ribbed cage and a deodorizing base, wherein two deodorizing bases are provided; the outer membrane and the inner membrane are held by the air-ribbed cage, with both ends of the outer membrane and the inner membrane respectively fixed to the two deodorizing bases, whereby a closed space is formed between the outer membrane and the inner membrane; the inner side of the inner membrane is used for placing the composting piles, with the malodor and water vapor generated from the composting piles entering into the closed space formed between the outer membrane and the inner membrane through the inner membrane, so that the water vapor is condensed into the water in the closed space, and the malodor molecules are absorbed and dissolved into the condensed water, thus forming the waste water which falls along the inner side of the outer membrane and the outer side of the inner membrane to the b

Abstract: The present invention relates to a method for inhibiting the formation of dioxin-like compounds in solid waste incineration flue gases, belonging to the field of cleaning of solid waste incineration flue gases. In accordance with the present invention, when incineration flue gases cool down to 500˜450° C., the flue gases are introduced into an inhibition reactor where copper chlorides in flue gas particulates mix and react with inhibitors to convert into copper metaphosphate so as to inactivate the copper chlorides which can catalyze the formation of dioxin-like compounds and control dioxin-like compound pollutants in incineration flue gases at the source. Compared with the prior art, the invention can effectively control the main formation ways of dioxin-like compounds in solid waste incineration flue gases by optimizing inhibitors and reaction conditions.

Abstract: The present invention discloses a method and a system of treating biomass wastes by biochemistry-thermochemistry multi-point interconnection. The present invention applies solid, gas and liquid products of the thermochemical treatment subsystem to the biochemical treatment subsystem and applies heat produced by the biochemical treatment subsystem to the thermochemical treatment subsystem, forming multi-point and two-way interconnection between the biochemical treatment subsystem and the thermochemical treatment subsystem, thereby increasing the yield and stability of energy gas of the biochemical treatment subsystem and reducing pollution and energy consumption of the thermochemical treatment subsystem respectively. The present invention is suitable for treating biomass wastes with high and low water contents at the same time, producing soil amendment, liquid fuel and biogas, having properties of low secondary pollution and significant reduction of greenhouse gas emission and so on.
