实现垃圾分类处理，关系广大人民群众生活环境，关系节约使用资源，也是社会文明水平 的一个重要体现。今天，随着绿源志愿者，我们来到了宝安老虎坑垃圾发电厂，进行一上午的参观学习。垃圾分类新时尚，深圳生活新方式。今天学习的主要内容，是了解垃圾处理的主要方式。

Bao 'an tiger pit garbage power plant

The realization of garbage classification and treatment is related to the living environment of the masses and the economical use of resources. It is also an important manifestation of the level of social civilization. Today, with the volunteers of lvyuan, we came to Baoan tiger pit garbage power plant for a morning visit and study. Garbage classification new fashion, Shenzhen new way of life. The main content of today's study is to understand the main ways of garbage disposal.

2. 填埋处理，垃圾填埋需要占用大量的土地资源，一般只适合于人口稀少，土地资源丰富的地区，深圳全市目前有下坪固体废弃物填埋场，宝安区老虎坑垃圾填埋场，坪山鸭糊垃圾填埋厂三个垃圾填埋场。其中前两个已经处于超负荷运作状态。宝安老虎坑一期卫生填埋场于2001年3月动工，2002年12月投入使用，由政府投资1.7亿元建设。设计库容850万立方米，封场工程2013年底动工，目前填埋场一期已完成封场工程，封场面积为26.4万平方米，基本实现“防治污染、固土保水、节能环保、焕然一新”的要求。老虎坑二期卫生填埋场设计库容960万立方米，分为西、中、东三区分别建设，其中西区工程设计库容为320万立方米，于2013年底完工并于2014年3月投入使用，目前已基本填满并实施中间覆盖；中区工程设计库容约280万立方米，于2015年11月开工，2017年7月底投入使用至今。严格按照标准，确保垃圾无害化填埋处理，与焚烧坑一并解决深圳每年700t垃圾。但是占地面积大，人均圾量持续增加，目前，填埋场日均填埋垃圾约2300吨，另有飞灰及无法资源化利用的炉渣残余物约120吨/日，2400吨/日的填埋速率已严重超设计处理量（840吨/日），按照当前的填埋处理增长速度，中区剩余库容可填埋天数为一年左右。

2. Landfill treatment, landfill needs to occupy a large amount of land resources, generally only suitable for the sparsely populated areas with rich land resources. Currently, there are three landfill sites in shenzhen: xiaping solid waste landfill, hukeng landfill in baoan district, and pingshan duck paste landfill. The first two are already in overdrive. The first phase of baoan tiger pit sanitary landfill was started in March 2001 and put into use in December 2002, with a government investment of 170 million yuan. The designed storage capacity is 8.5 million cubic meters, and the sealing project started at the end of 2013. At present, the first phase of the landfill has completed the sealing project, covering an area of 264,000 square meters, basically fulfilling the requirements of "preventing pollution, retaining soil and water, saving energy and environmental protection, and taking on a new look". The designed reservoir capacity of the tikeng ii sanitary landfill is 9.6 million cubic meters, which is divided into the western, central and eastern three areas. The western project, with a designed reservoir capacity of 3.2 million cubic meters, was completed at the end of 2013 and put into use in March 2014. The designed reservoir in the central district, with a capacity of about 2.8 million cubic meters, was started in November 2015 and has been in use since the end of July 2017. Strictly in accordance with the standards, to ensure the garbage harmless landfill treatment, and incineration pit together to solve the shenzhen annual 700t garbage. But covers an area of big, there the amount per capita continues to increase, at present, landfill landfill disposal of about 2300 tons a day, fly ash and otherwise not resource-oriented utilization of slag residue of about 120 tons/day, 2400 tons/day rate of landfill has been seriously ultra design capacity (840 tons/day), according to the current landfill treatment rate, the central residual capacity can be filled days for a year or so.

相比之下，我们第三种方法-焚烧处理，占地少，有利于节约土地资源；垃圾无害化处理彻底，二次污染可控，对环境，人体影响小；减量化效果好，焚烧后减容90%，减重80%；产生蒸汽可用于发电，供热等多种用途，变废为宝。焚烧处理已经成为深圳最理想的垃圾处理方式。

In contrast, our third method - incineration treatment, less land, is conducive to saving land resources; Garbage harmless treatment thoroughly, secondary pollution control, little impact on the environment, human body; The reduction effect is good. After burning, the capacity is reduced by 90% and the weight is reduced by 80%. Steam generation can be used for power generation, heating and other purposes, turning waste into treasure. Incineration has become the most ideal waste disposal method in Shenzhen.

深圳市宝安能源生态园二期投产以来，累计处置生活垃圾约750万吨，产生清洁电能约27亿度，节约垃圾填埋土地超46万平方米，为国家节约标准煤达100万吨，减少二氧化碳及氮氧化物排放分别为260万顿。0.7万吨。每年所产生的清洁能源可满足20万户城镇居民用电需求，每年所节约的土地可新建一座万达广场。每年向周边企业提供热蒸汽15万吨，实现绿色循环经济规模约20亿元，增加社区收入8000万元，创造工作岗位5000个。

Since the second phase of Shenzhen baoan energy ecological park was put into operation, it has disposed of about 7.5 million tons of domestic garbage, generated about 2.7 billion kilowatt hours of clean electricity, saved more than 460,000 square meters of landfill land, saved 1 million tons of standard coal for the country, and reduced the emission of carbon dioxide and nitrogen oxides by 2.6 million tons. 07000 tons. The clean energy generated each year can meet the electricity demand of 200,000 urban households, and the land saved each year can be used to build a new wanda plaza. It provides 150,000 tons of hot steam to surrounding enterprises every year, realizing a green circular economy of about 2 billion yuan, increasing community income by 80 million yuan and creating 5,000 jobs.

如此一座高效的生态园，保安老虎坑垃圾发电场究竟有什么样的奥秘，跟随绿源志愿者，让我们一同揭晓。

Such an efficient ecological park, the security tiger pit garbage farm has what kind of mystery, follow the green source volunteers, let us reveal.

垃圾回收处理分为三部分，由居民到垃圾转运站最后到达处理厂。大多数到达处理厂的垃圾，都是经过分类后的其他垃圾。第一步，垃圾倾倒。老虎坑的焚烧场由四个主坑组成。先经过渗沥水池除去部分污水废水，还可达到去臭的效果。第二步，炉渣处理。紧接着成吨的垃圾进入焚烧车间，二期锅炉车间内布置有四台锅炉，锅炉地步0米主要布置一次风系统，炉底输渣系统和出渣机，看火平台位于8米，14米平台往下为焚烧炉，往上为余热炉。以及蒸汽发电系统。第三部到了我们的焚烧车间，整个车间位于室内，侧墙均安装了排风机使车间处于微负压状态，有效阻止臭味散发。运进焚烧炉的垃圾，会首先经过工作人员用机动铁钩翻到，除水分，静置4-5天，减少垃圾热值，加上优化设计的炉膛，才能确保垃圾稳定而充分的燃烧。烟气间布置有半干式反应塔，布袋除尘器，输灰气等设备。烟气净化处理采用半干法处理系统，及余热锅炉出口烟气进入旋转喷雾反应塔中，告诉旋转喷雾器将石灰浆雾化后喷入烟气，与烟气中的酸性气体发生反应，同时冷却过程中二恶英，呋喃和重金属产生凝结。反应生成物由反应塔底部排出，部分随烟气一起进入进入袋式除尘器，在袋式除尘器酸性气体与反应剂进一步反应，提高酸性气体的去除率。烟气中的各种颗粒附着于滤袋表面，经过压缩空气反吹排入除尘器灰斗。清洁烟气经过引风机，通告脱销系统后经过80m高的烟囱排入大气。经过该工艺处理，烟气排放指标远优于国家标准，既环保卫生，又高效清洁，不愧是一只“乖乖虎”。

Garbage collection is divided into three parts, from the residents to the garbage transfer station and finally to the treatment plant. Most of the waste that arrives at the plant is other waste that has been sorted. Step 1: dump. The tiger pit incinerator consists of four main pits. After the first infiltration of the pool to remove part of the wastewater, but also to achieve the effect of deodorization. The second step is slag treatment. Then tons of garbage into the incineration workshop, the second boiler workshop is arranged with four boilers, the boiler point of 0 meters is mainly arranged with a primary air system, furnace bottom slag system and slag machine, see the fire platform is located at 8 meters, 14 meters of the platform for the incinerator down, up for the waste heat furnace. And steam power systems. The third part came to our incineration workshop. The whole workshop was located indoors, and exhaust fans were installed on the side walls to make the workshop in a state of micro-negative pressure, effectively preventing odor emission. The garbage transported into the incinerator will first be turned over by the staff with a mobile iron hook to remove moisture and stand for 4-5 days to reduce the heat value of the garbage. In addition to the optimized design of the furnace, the stable and sufficient combustion of the garbage can be ensured. There are semi-dry reaction tower, bag filter, ash gas and other equipment arranged between the flue gas. The flue gas purification treatment adopts the semi-dry treatment system, and the flue gas from the waste heat boiler outlet enters the rotating spray reaction tower. The rotating sprayer is told to spray the lime slurry into the flue gas after atomization, and react with the acid gas in the flue gas. Meanwhile, during the cooling process, the dioxins, furans and heavy metals produce condensation. The reaction products are discharged from the bottom of the reaction tower, and some of them go into the bag filter along with the flue gas. The acid gas of the bag filter further reacts with the reactants to improve the removal rate of acid gas. All kinds of particles in the flue gas adhere to the surface of the filter bag, after the compressed air back into the dust collector hopper. Clean smoke passes through the induced draft fan, announces the out of stock system, and then drains into the atmosphere through an 80m-high chimney. After this process, the emission index of flue gas is far better than the national standard, which is not only environmentally friendly and hygienic, but also highly efficient and clean.

讲到最后，垃圾分类新时尚，深圳生活新方式。了解了垃圾处理方式，我们是不是应该加倍珍惜身边的环境呢，让我们一起携手走向更美好的未来！

In the end, garbage classification is a new fashion and a new way of life in Shenzhen. Understand the garbage disposal, we should value of the environment around it, let us work together for a better future!
