厨余废水特征:
餐厨垃圾在堆放和处理过程中由于压实、发酵等生物化学降解作用产生了一种高浓度的有机或无机成份的污水。污水成分复杂,污染物浓度高,散发极其难闻的恶臭,并具有污水水质极不稳定的特点,与城市管网污水水质相比,其主要污染物指标超过很多,若直接排入城市管网会对污水处理厂造成冲击负荷,影响污水处理厂的稳定运行。
厨余废水产生:
厨余污水是餐饮行业产生的污水,餐饮业的发展带来了大量的厨余污水,为了食品安全,厨余垃圾不能直接做饲料用,因此要经过无害化处理来避免污染环境和影响人类健康。处理厨余污水要兼顾处理效果和经济、易操作。
叠螺式污泥脱水机用在厨余废水的哪一个阶段?
厨余污水中含有大量的残渣剩饭,常用的处理方式是先采用粉碎机将里边的大颗粒物粉碎,然后进入调节池,经过调节之后进入气浮机,经过气浮机处理过后的水进入厌氧、好氧环节,通过厌氧、好氧处理,污水中的有机物分解,污水进入沉淀池,然后用过叠螺机实现污泥的固液分离,将污水中的污泥挤压出来。
叠螺机作为厨余污水处理中污泥处理的环节是非常重要的。经过叠螺机处理之后,污水基本变清,污泥被挤压成泥饼。为厨余污水处理做好了收尾工作。
叠螺机的优势:
1、产品规格多样,系列齐全,针对不同的处理规模,可选择合适的机型,避免大材小用。
2、机体设计紧凑,浓缩脱水一体化,本身带有电控柜和污泥絮凝混合槽等辅助装置,对配套设备兼容性强,便于设计。
3、小型设计,便于因地制宜,可减少脱水机本身的占地空间和建设成本。
4、具备污泥浓缩功能,故不需要浓缩及贮存单元,减少污水处理设施整体的占地空间和建设成本。
5、叠螺机主体具有自我清洗功能,故不必为防止污泥堵塞而大量用水清洗。
6、采用低速螺旋挤压技术,耗电低。
7、电控柜设自控装置,从输送污泥、注入药液、浓缩脱水、至排出泥饼,实现24小时全自动连续无人运行,降低工人费。
