一般生活垃圾处理的工艺流程是怎样的?
Date﹕2020-10-29|Source:Eclear Environmental
       人们在日常生活中会产生很多的垃圾,这些垃圾掺杂在一起一般会产生很大的臭气,这些臭气不仅味道难闻,对人体有着极大的损害,对环境的影响也非常大。所以,这些垃圾一般都会放到垃圾站进行统一处理,而垃圾站处理垃圾并不是说随意就埋了或者烧了,他是一步步进行处理的,下面我们就看看一般生活垃圾处理的工艺流程是怎样的。

垃圾站除臭


       一、垃圾进场

       经垃圾车收运的生活垃圾进入处理厂的垃圾暂存间,垃圾暂存间为微负压的密封结构且车辆入口处设有风幕防止气味外泄,同时垃圾池上方的喷淋装置通过喷洒药剂进行除臭驱蝇作业,同时垃圾暂存池的渗滤液收集系统对渗滤液进行收集并输送到污水处理车间。

       二、综合分选

       生活垃圾经由行车抓斗上料至板式上料机,经由均匀布料器进行均匀连续给料至人工分选平台,通过人工分选出建筑垃圾做再生骨料和大件可燃物进行撕碎,剩余部分经破袋机破袋后通过滚筒筛分选出渣土有机物进行制肥,经磁选机除铁后剩余部分通过风选机分选出轻物质做木塑处理、可燃物热解气化、重物质做再生骨料。

       三、水解喷爆

       经综合分选分选出的有机物进入到高温高压的水解喷爆罐,加入催化剂、水蒸气和热空气,在150-200℃的温度下水解1h。水解后物料经1-2h的脱水后,在有机物含水量降低至45%左右时水解结束后喷爆至密闭的卸料间,由输送设备输送在制肥造粒车间。

       四、制肥造粒

       水解后的有机物进入堆肥车间的发酵槽,加入菌种后进行发酵,发酵后的有机物经粉碎后进行筛分,其中3mm左右小颗粒有机物进入配料仓,加入氮磷钾的微量元素后经混料机混料,并输送至造粒机进行造粒后并进行烘干,烘干后通过冷却机冷却至室温,然后有机肥颗粒通过三级筛分机筛分出成品料进行称重装袋,并入库待售,过大和过小的颗粒经粉碎后重新返回造粒。

       五、热解气化

       综合分选分选出的可燃物经撕碎后进入热解气化车间,在高温、缺氧的条件下将有机物进行充分的热解,将有机物大分子态裂解成小分子态可燃气体,剩余物为熔融炉渣。经热解气化产生的可燃气体可进行发电。在热解气化的过程中同时进行尾气处理。

       六、木塑处理

       经生活垃圾分选出的轻物质进入到木塑处理车间,轻物质主要为废旧塑料、纸张、树叶等物质,经粉碎后的轻物质和一定比例的木质粉料混合后经热挤压成型,制成木塑板材或型材。

       七、除臭及污水处理

            在生活垃圾综合处理过程中,通过管道将设备内的空气输送至除臭塔,使设备内部呈微负压,防止气味外泄。同时污水处理系统对生产过程中产生的污水进行处理,防止对周围环境造成污染。
