This invention relates to the field of polymer degradable materials technology, specifically to a biodegradable material, its preparation method, and its applications. The material is based on modified polylactic acid (PLA), supplemented by antioxidants, plasticizers, flame retardants, and inorganic fillers in specific weight proportions. Its unique feature lies in the polymerization of lactic acid and epicatechin imidazole ammonium chloride polymer under stannous octoate catalysis, using chemical bonding to introduce the bioactive groups of epicatechin into the PLA backbone, significantly improving the material's biodegradation rate, mechanical properties, and thermal stability. The bioactive substances and ionic groups in this material promote microbial degradation, achieving complete decomposition in a composting environment within a short time. Simultaneously, through molecular-level reinforcement and ionic cross-linking effects, the strength, toughness, and high-temperature processing performance of PLA are effectively improved. This material can be widely used in disposable tableware, food packaging films, and biodegradable agricultural mulch films.

The invention belongs to the field of oil and gas field environmental protection equipment, and relates to a petroleum-contaminated soil microbiological treatment self-ploughing system and method, which are suitable for performing petroleum-contaminated soil microbiological treatment by adopting a composting process. The soil above is pushed to displace through gradual expansion of the ploughing rubber air bag, automatic ploughing in the treatment process is achieved, the oxygen content in the soil is increased, the growth and reproduction environment of microorganisms is improved, and therefore the biodegradation process of petroleum hydrocarbon is accelerated.

This utility model relates to the field of sludge treatment technology, specifically a sludge treatment screening and filtration mechanism, including a screening and filtration box. An installation plate is mounted below the stirring assembly, and an aeration assembly is located below the installation plate. The aeration assembly includes an aerator, an air supply pipe, a fixed plate, and multiple aeration heads. The output end of the aerator is connected to one end of the air supply pipe, and one end of each aeration head is fixedly mounted on the side wall of the air supply pipe. A filter assembly is installed below the aeration assembly. This utility model mainly reduces the total volume of sludge by mixing a separating agent with the sludge, through water removal and particle aggregation. The aeration process not only accelerates the biodegradation process in the sludge but also suspends the solid particles in the sludge, allowing for more thorough contact and reaction with the agent, thereby enhancing the effect of reducing sludge volume.
