Abstract: An integrated device and a method thereof are provided. The integrated device includes: a pyrolysis chamber, a high-temperature cracking chamber, a material drying chamber, a steam boiler, a cyclonic dust removal chamber, a spray chamber, an electrostatic dust removal chamber, a water bath purification chamber, a biomass gas treatment chamber, and a metal carbonization chamber. The pyrolysis chamber is connected to the high-temperature cracking chamber. The pyrolysis chamber is provided with the first biomass air inlet. The high-temperature cracking chamber is provided with a second biomass air inlet and is connected to the material drying chamber through a lower hot air pipe and an upper hot air pipe. An air-drying cylinder is arranged in the material drying chamber. The upper hot air pipe is in communication with an interior of the air-drying cylinder. The lower hot air pipe is in communication with a space outside the air-drying cylinder.

Abstract: Disclosed are a constructed wetland structure and methods for preparing and using a carbon source, which relate to the technical field of biological treatment of water pollutants, and solve the problems of poor uniformity, complexity, unsatisfactory effects and high operating costs in existing carbon source adding methods. The present disclosure includes a water inlet pond, a treatment unit, and a water storage pond, which communicate in sequence. In the treatment unit, plant straws and biochar are used to prepare a carbon source. By modifying the carbon source material, the carbon source is released stably. By arranging carbon source layers, under the action of a water flow, the uniformity of carbon source distribution is guaranteed. The carbon source is periodically cleaned and replaced. Carbon source material is a biomass material which features a wide source and low costs.

Abstract: Provided are an ecological slope anti-corrosion timber pile and a treatment device and method therefor, belonging to the field of ecological engineering. The device includes a gasification furnace, and first, second and third carbonization chambers, each internally provided with a main gas pipeline, and multiple rows of radially distributed branch gas pipes are vertically disposed thereon and provided with electronic igniters. Multiple rows of radially distributed timber piles are vertically inside the carbonization chambers and between the branch gas pipes. The gasification furnace is connected to the main gas pipeline of the first carbonization chamber through a gas booster pump. The first carbonization chamber is connected to an air blower, the first and second carbonization chambers are connected through a joint pipe, the second and third carbonization chambers are connected through a pipeline, and the third carbonization chamber is connected to the gasification furnace through a gas delivery pipe.

Abstract: The present invention discloses a BiOCl photocatalyst with a super degradation effect. BiOCl is prepared into a special micro-nano ellipsoid structure which significantly improves catalysis efficiency under visible light. With the present invention, degradation rates with gas phase formaldehyde, Congo red solution and hexavalent chromium solution can reach above 90%. Moreover, due to a stable structure, the BiOCl photocatalyst has desired reusability which enables a lower cost of the photocatalyst and wider use in the field of environmental pollution treatment.
