Product Details
    污泥是污水处理后的产物,是一种由有机残片、细菌菌体、无机颗粒、胶体等组成的极其复杂的非均质体。污泥的主要特性是含水率高(可高达99%以上),有机物含量高,容易腐化发臭,并且颗粒较细,比重较小,呈胶状液态。它是介于液体和固体之间的浓稠物,可以用泵运输,但它很难通过沉降进行固液分离。

污泥脱水与干化

污泥脱水是整个污泥处理工艺的一个重要的环节,其目的是使固体富集,减少污泥体积,为污泥的最终处置创造条件。为使污泥液相和固相分离,必须克服它们之间的结合力,所以污泥脱水所遇到的主要问题是能量问题。针对结合力的不同形式,有目的采用不同的外界措施可以取得不同的脱水效果。污泥脱水与干化包括自然脱水、机械脱水和热处理干化。   污泥经浓缩、消化后,尚有95%~97%含水率,且易腐败发臭,需对污泥作干化与脱水处理。常用脱水方法有自然干燥和机械脱水两种。利用芦苇等沼生植物也可以进行较好的脱水。

     污泥中含水率的多少与污泥烘干、处理工艺、污泥状态及流动性能密切相关。通常浓缩可将含水率降到85%(含水状态),含水率在70~75%时,污泥呈柔软状态,不易流动;通常一般脱水只可降到60~65%,此时几乎成为固体,含水率低到35%~40%时,呈聚散状态(以上是半干化状态);进一步低到10%~15%则呈粉末状。 

污泥水分干燥

为了进一步降低脱水后污泥的含水率(75%),采用干燥工艺。经干燥后含水率可降至约20%左右。干燥工艺除了最简单的日晒外,常用的是热干燥技术。污泥热干燥开始于本世纪初的英国,此方法可以完全杀灭病原菌,使污泥处于稳定化状态。但干燥过程产生的大量的废气净化费用问题、运行费用,都是使用干燥工艺要考虑的问题。

检测污泥水分的测定原理

深圳市艾格瑞仪器有限公司通过与国外仪器厂商进行合作研发生产的高场能粮食快速水分仪,通过仪器发出的高场能磁场信号,在高场能磁场信号经过水分子后,仪器进行感应接收,然后对接收回来的信号进行分析,瞬间得出结果。有效解决了传统烘箱检测的时效性问题,测量样品几秒出结果,结果准确,可靠。通过高场能的原理,又能有效解决传统便携水分仪所带来的准确性不高,测量受温度等因素影响的问题。所以,艾格瑞SH-02高场能污泥水分仪具有:操作简单,测量速度快,准确性高,价格低廉等优点,是传统烘箱法和传统便携水分仪的替代产品。

污泥水分测定仪的主要特点

1、引进国外先进技术基础,采用高场能磁场发射器及高场能磁场接收器相结合,

2信号稳定,结果准确

3具有超强的穿透能力

4性能稳定,品质优良

5仪器设计精巧,结构紧凑

6可在现场快速测定被测物水分。

淤泥水分测定仪技术参数:

1. 测定水分范围: 0—99%

2. 档位:   6个修正档位

3. 显示:   LCD液晶数字显示

4. 使用环境:  -25-+60℃

5. 体积:    长205×65×50mm

6. 电源:    9V电池(6F22型)

7. 重量:    0.24KG

艾格瑞水分仪操作步骤:

1. 测定污泥水分前,手持仪器(探头勿与被测物接触),打开开关(将开关拨到ON)数字显示在±00.5以内,若不在其范围内,应缓慢旋动调零旋钮,使数字显示在±00.5以内即可。

2. 仪器零位调整好后,即可以测定水分了,将探针全部插进被测污泥中,此时的读数即为被测物品的实际含水率。
