技术领域technical field
本发明涉及污水处理技术领域,具体涉及一种叠加式污水处理设备。The invention relates to the technical field of sewage treatment, in particular to a stacked sewage treatment equipment.
背景技术Background technique
污水处理是指为使污水达到排水某一水体或再次使用的水质要求对其进行净化的过程。污水处理被广泛应用于建筑、农业,交通、能源、石化、环保、城市景观、医疗、餐饮等各个领域,也越来越多地走进寻常百姓的日常生活。现有的污水处理设备占用场地面积较大,土地成本较高,处理成本难以承受等,使一些城镇污水处理厂成为“污染集中排放源”,对当地的环境状况造成二次污染。随着时代和科技的发展,人民生活水平日益提高,人类对生存环境的要求也越来越高,水资源的污染已经成为社会最关注的问题之一,大量的污水排放,进一步破坏了水环境,特别是一些化工企业, 污水在不经过处理的情况下直接排放到河道中,严重破坏了环境,影响了人们的生产和生活。因此,对污水的处理工程迫在眉睫。在科技高速发展的今天, 各大中小污水处理厂林立, 各种污水处理设备层出不穷,如曝气机、污水处理池、净化设备等,而污水处理池是各个污水处理厂中最常见的污水处理设备,根据所要处理不同性质的污水,选择使用不同类型的污水处理池。在污水处理工程中,污水中的无机颗粒不仅会磨损设备和管道,降低活性污泥活性,而且会板积在反应池底部减小反应器有效容积,甚至在脱水时扎破滤带损坏脱水设备,而且污水处理效果也不太好,另外随着工业的发展,土地资源已经制约着城市的发展,而污水处理设备往往需要占用比较大的面积,这对土地资源来说是一种浪费。Sewage treatment refers to the process of purifying sewage to meet the water quality requirements of a certain water body for drainage or reuse. Sewage treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, medical treatment, catering, etc., and it is also increasingly entering the daily life of ordinary people. The existing sewage treatment equipment occupies a large area, the land cost is high, and the treatment cost is unbearable, etc., making some urban sewage treatment plants become "concentrated pollution discharge sources", causing secondary pollution to the local environmental conditions. With the development of the times and science and technology, people's living standards are improving day by day, and human beings have higher and higher requirements for the living environment. The pollution of water resources has become one of the most concerned issues of the society. A large amount of sewage discharge has further damaged the water environment. , especially some chemical companies, the sewage is directly discharged into the river without treatment, which seriously damages the environment and affects people's production and life. Therefore, the sewage treatment project is imminent. Today, with the rapid development of science and technology, there are many large, medium and small sewage treatment plants, and various sewage treatment equipment emerge in an endless stream, such as aerators, sewage treatment tanks, purification equipment, etc., and sewage treatment tanks are the most common sewage treatment in various sewage treatment plants. According to the different types of sewage to be treated, different types of sewage treatment tanks are selected. In sewage treatment projects, inorganic particles in sewage will not only wear equipment and pipelines, reduce the activity of activated sludge, but also accumulate at the bottom of the reaction tank to reduce the effective volume of the reactor, and even break the filter belt during dehydration and damage the dehydration equipment. , and the effect of sewage treatment is not very good. In addition, with the development of industry, land resources have restricted the development of cities, and sewage treatment equipment often needs to occupy a relatively large area, which is a waste of land resources.

本发明在使用时,污水通过排污管道进入一级沉淀腔内,设有的栅格能阻拦较大的杂物的通过,经过振动臂的振动,使得污水中的无机颗粒伴随着污水的震动加速沉淀,同时也将污水中的絮凝物加速上升并漂浮在污水表面上,沉砂污泥等落入收斗中;通过提升泵将一级沉淀腔上层的污水输送至厌氧处理腔中,所述厌氧处理腔中设有的弹性立体填料具有吸附作用,能形成丰富的厌氧及兼性菌群,不仅可以降解部分有机污染物,还可将复杂的大分子有机物水杰,转化为简单的小分子物质,同时将不易于好氧生物降解的物质转化为易于降解物;污水在厌氧处理腔中设有的潜流推进器的作用下,停留一段时间后进入好氧处理腔中,在好氧处理腔的滤料和所述曝气管道的曝气作用下,形成好氧微生物群,从而进一步分解水中有机污染物,在分解过程中,通过所述气提装置可将好氧处理腔底部的污水上下翻滚,将一部分污染物变为气泡,起到更容易分解污染物的作用;好氧处理腔中出来的污水通过输送管道进入二级沉淀腔中,污水源源不断进入斜管中,一些碎片和小絮体被沉淀分离出来,堆积至二级沉淀腔底部,而净化后的水则通过所述储水箱在所述上腔体外部设有的出水管排出设备外部,另外沉淀过程中通过配水管的分配下,多个所述斜管均得到等量的污水,因而二级沉淀腔底部堆积的污泥不会因为某个斜管污水量过大而将已经沉降的污泥再次冲起;二级沉淀腔沉淀后的污泥通过定期启动控制阀将污泥回流管道打开,将污泥再次进入厌氧处理腔继续进行分解。When the present invention is in use, the sewage enters the first-stage sedimentation chamber through the sewage pipe, and the grid provided can block the passage of larger debris, and the vibration of the vibrating arm makes the inorganic particles in the sewage accelerate with the vibration of the sewage At the same time, the flocs in the sewage are accelerated to rise and float on the surface of the sewage, and the grit sludge, etc. fall into the collection bucket; the sewage from the upper layer of the first-stage sedimentation chamber is transported to the anaerobic treatment chamber through the lift pump, so that The elastic three-dimensional packing in the anaerobic treatment chamber has adsorption effect and can form a rich anaerobic and facultative flora, which can not only degrade some organic pollutants, but also convert complex macromolecular organic substances into simple At the same time, the substances that are not easy to be degraded by aerobic biodegradation are converted into easily degradable substances; the sewage enters the aerobic treatment chamber after staying for a period of time under the action of the submerged propeller provided in the anaerobic treatment chamber. Under the action of the filter material of the aerobic treatment chamber and the aeration of the aeration pipeline, an aerobic microbial group is formed to further decompose the organic pollutants in the water. During the decomposition process, the aerobic treatment chamber can be The sewage at the bottom rolls up and down, turning part of the pollutants into air bubbles, which makes it easier to decompose the pollutants; the sewage from the aerobic treatment chamber enters the secondary sedimentation chamber through the conveying pipeline, and the sewage continuously enters the inclined pipe. Some debris and small flocs are separated by sedimentation and accumulated to the bottom of the secondary sedimentation chamber, while the purified water is discharged from the outside of the equipment through the water outlet pipe provided outside the upper chamber by the water storage tank. In addition, during the sedimentation process Under the distribution of water distribution pipes, the same amount of sewage can be obtained from multiple inclined pipes, so the sludge accumulated at the bottom of the secondary sedimentation chamber will not flush the settled sludge again due to the excessive amount of sewage in a certain inclined pipe. After the sedimentation in the secondary sedimentation chamber, the sludge return pipe is opened by periodically starting the control valve, and the sludge enters the anaerobic treatment chamber again for further decomposition.
