Provided is a reaction apparatus for comprehensively measuring biodegradability of a material, comprising a device frame, an electrical control cabinet and a reaction chamber monomer. The upper side of the reaction chamber monomer is a reaction chamber body, and the lower part is a material receiving trolley. The top of the reaction chamber body is sealed by a chamber cover. A side wall is pasted with an electric heating plate and a thermal insulation cotton. A stirring paddle is arranged inside. An air inlet and an air outlet are respectively provided on a front and a rear wall. A discharging mechanism is located below. The electrical control cabinet separately controls the reaction conditions of each reaction chamber monomer. The present invention further relates to a use method thereof, which can realize the biodegradability evaluation in such three aspects as material degradation rate, disintegration rate and ecological non-toxicity test.

The invention discloses a spatial and temporal feature-based method for measuring domestic wastewater effluent loadings, comprising the following steps: establish a model for measuring regional domestic wastewater effluent loadings; calculate regional population distribution raster data; obtain per capita effluent loading coefficients with spatial and temporal differences; calculate regional domestic wastewater effluent loadings; and compare and analyze the temporal fluctuation features and spatial variation features of regional domestic wastewater effluent loadings and identify 'hotspot' periods and areas of effluent loadings. Compared with the prior art, the method for measuring domestic wastewater effluent loadings provided by the present invention is flexible, convenient and highly universal, which can significantly raise the temporal-spatial resolution of the pattern of regional domestic wastewater effluent loadings. The data needed are also publicly available. This invention can help identify key pollution areas and periods and lay a methodological foundation for precision pollution control.

The present application provides a method for fully recycling kitchen waste by usingL. and aerobic microorganisms. The method includes first performing solid-liquid separation on the kitchen waste; then using the filtrate obtained through separation to feed young larvae ofL. to convert salt in the filtrate into body fluid ofL. in a larval stage, and using the kitchen waste filter residue to feed 2-6-instar larvae ofL. respectively; separating insects and insect feces residue in a timely manner, so as to reduce a salt content of insect feces and improve transabdominal transformation efficiency ofL. and quality of the insect manure; and finally implementing full resource utilization through aerobic composting and insect drying and sterilization treatment.
