Description
所属技术领域Technical field
本实用新型涉及一种城市生活垃圾处理厂恶臭气体处理装置，用于城市生活垃圾综合分选、堆肥和填埋等垃圾处理过程中产生的恶臭气体处理，属于环境保护技术领域。The utility model relates to a malodorous gas treatment device of an urban domestic garbage treatment plant, which is used for the treatment of the malodorous gas generated in the comprehensive sorting of urban domestic garbage, composting, landfill and other garbage treatment processes, and belongs to the technical field of environmental protection.
背景技术Background technique
在城市生活垃圾综合分选、堆肥和填埋处理过程中，会产生主要成分为硫化氢、硫醇类、氨和挥发性有机化合物的恶臭气体。城市生活垃圾厂产生的恶臭气体阈值浓度低，对设备和管道有强烈腐蚀性，还会对正常工业生产和周边居民的日常生活造成干扰，产生严重的人体健康和生态环境危害。During the comprehensive sorting, composting and landfill treatment of municipal solid waste, malodorous gases mainly composed of hydrogen sulfide, mercaptans, ammonia and volatile organic compounds will be produced. The threshold concentration of malodorous gas produced by municipal solid waste plants is low, which is highly corrosive to equipment and pipelines, and will also interfere with normal industrial production and the daily life of surrounding residents, causing serious harm to human health and the ecological environment.
用于城市生活垃圾处理厂恶臭气体的常规处理技术主要包括吸收、吸附、催化、焚烧和等离子体技术等。近年来，生物处理技术特别是生物过滤技术由于设备简单、处理效率高、投资和运行费用低、无二次污染等优点，逐渐应用于含硫恶臭气体的处理。然而由于石油、化工和石化污水处理过程中产生的含硫恶臭气体浓度相对较高，除含有硫化氢、氨和挥发性有机化合物外，还可能含有甲硫醇、乙硫醇和乙硫醚物质，组成复杂。特别是含硫、氨气体生物降解过程中产生的酸性物质易导致系统pH降低，从而引起系统处理效率的降低。可见，常规生物处理装置在处理城市生活垃圾处理厂含硫恶臭气体时，存在着处理效率低、很难实现达标排放、系统运行不稳定等弊端。Conventional treatment technologies for malodorous gases in municipal solid waste treatment plants mainly include absorption, adsorption, catalysis, incineration and plasma technologies. In recent years, biological treatment technology, especially biological filtration technology, has been gradually applied to the treatment of sulfur-containing odorous gases due to the advantages of simple equipment, high treatment efficiency, low investment and operating costs, and no secondary pollution. However, due to the relatively high concentration of sulfur-containing malodorous gases produced in the process of petroleum, chemical and petrochemical sewage treatment, in addition to hydrogen sulfide, ammonia and volatile organic compounds, it may also contain methyl mercaptan, ethyl mercaptan and ethyl sulfide substances. The composition is complex. In particular, the acidic substances produced during the biodegradation of sulfur-containing and ammonia-containing gases can easily lead to a decrease in the pH of the system, resulting in a decrease in the treatment efficiency of the system. It can be seen that conventional biological treatment devices have disadvantages such as low treatment efficiency, difficulty in achieving standard discharge, and unstable system operation when dealing with sulfur-containing odorous gases from municipal solid waste treatment plants.
发明内容Contents of the invention
为了克服现有的城市生活垃圾处理厂恶臭气体处理装置处理效率低，很难实现达标排放、系统运行不稳定等不足，本实用新型提供一种城市生活垃圾处理厂恶臭气体处理装置，该处理装置结构简单、占地面积小，能够实现城市生活垃圾厂恶臭气体的达标排放。In order to overcome the shortcomings of the existing malodorous gas treatment devices in urban domestic waste treatment plants, such as low treatment efficiency, difficulty in achieving standard discharge, and unstable system operation, the utility model provides a malodorous gas treatment device in urban domestic waste treatment plants. The structure is simple and the floor area is small, and it can realize the standard discharge of odorous gas from municipal solid waste plants.
本实用新型解决其技术问题所采用的技术方案是：一种城市生活垃圾处理厂恶臭气体处理装置，由生物过滤单元和活性炭吸附单元组成。城市生活垃圾处理厂恶臭气体首先经过气体分布板均匀分布后进入填充陶粒、海绵双层高效活性生物填料的生物过滤单元中，发生生物吸收和生物降解反应。生物过滤单元内填充的双层活性生物填料为陶粒和聚氨酯海绵块，陶粒层和聚氨酯海绵层通过多孔隔板隔开，两层的体积比为1：1，其中陶粒的粒径为1.0-3.0mm，聚氨酯海绵块的粒径为3.0-5.0mm。生物过滤单元出气经气体输送管输送后进入活性炭吸附单元，恶臭气体经活性炭纤维和活性炭颗粒吸附后，尾气经设置在生物过滤单元底部的排气口排放。The technical scheme adopted by the utility model to solve the technical problem is: a treatment device for malodorous gas in a municipal solid waste treatment plant, which is composed of a biological filter unit and an activated carbon adsorption unit. The malodorous gas of the municipal solid waste treatment plant is first evenly distributed through the gas distribution plate, and then enters the biological filtration unit filled with ceramsite and sponge double-layer high-efficiency active biological fillers, where bioabsorption and biodegradation reactions occur. The double-layer active biological filler filled in the biological filtration unit is ceramsite and polyurethane sponge. The ceramsite layer and the polyurethane sponge layer are separated by a porous partition. The volume ratio of the two layers is 1:1, and the particle size of the ceramsite is 1.0-3.0mm, the particle size of the polyurethane sponge block is 3.0-5.0mm. The outlet gas of the biological filter unit is transported through the gas delivery pipe and enters the activated carbon adsorption unit. After the malodorous gas is absorbed by activated carbon fibers and activated carbon particles, the tail gas is discharged through the exhaust port at the bottom of the biological filter unit.
本实用新型的有益效果是，采用了先进的物化-高效生物组合处理技术，可高效、稳定、快速的处理城市生活垃圾处理厂恶臭气体。装置结构简单、紧凑，处理效果好，无二次污染物产生，投资和运行费用低。The beneficial effect of the utility model is that the advanced physicochemical-high-efficiency biological combined treatment technology can be used to efficiently, stably and quickly treat the malodorous gas of the municipal solid waste treatment plant. The structure of the device is simple and compact, the treatment effect is good, no secondary pollutants are produced, and the investment and operation costs are low.
