淤泥固化技术概述　　Overview of sludge solidification technology　　现有技术中，河道清淤技术主要包括以下几种：1、排干清淤：通过修建临时围堰，把待施工段的河道截封住，然后抽排水进行干挖作业或水力冲洗，以实现清淤的目的;2、水下清淤：通过借助清淤船作为施工平台，将一系列清淤装置放在船上，然后可直接在水面上进行淤泥开挖作业，再通过输送管道将开挖出来的淤泥运输到岸上堆放场;3、环保清淤：通过使用专业环保清淤设备，实现二次污染防治，保证有效的清淤深度和位置[1]。　　In the existing technology, the river dr

　　综合治理建设内容包括：河道内淤泥固化处理、截污、调蓄池、行洪能力的保持和提升、以及长期水质在线监测系统等。浦东河为黑臭河道，通过综合治理要求水体不黑臭，　　The construction contents of comprehensive treatment include: solidification treatment of sludge in the river, sewage interception, regulation and storage tank, maintenance and improvement of flood discharge capacity, long-term on-line water quality monitoring system, etc. Pudong river is a black and smelly river. Through comprehensive tr

　　河道淤泥固化处理工艺，包括以下步骤：　　The solidification treatment process of river sludge includes the following steps:　　预处理：采用泵水设备将河道内的表水抽排干净，直至露出河道底部的淤泥;　　Pretreatment: pump the surface water in the river channel with water pump equipment until the sludge at the bottom of the river channel is exposed;　　步骤一：对待固化处理的河道段的淤泥进行深度测量获得该河道段的淤泥深度，以及对该河道段的淤泥进行取样获得淤泥样本，对淤泥样本进行测试分析得出该河道段淤

　　目首先使固化剂与淤泥接触前就与水混合形成固化剂混合液，省去了常规工艺中洒干粉导致的配比不精确，固化剂干粉散布不均匀的问题，同时大大节约了固化剂的用量;　　Firstly, the curing agent is mixed with water before contacting with sludge to form the curing agent mixture, which eliminates the problems of inaccurate proportion and uneven distribution of curing agent dry powder caused by spraying dry powder in the conventional process, and greatly saves the amount of curing agent;　　其次，利用带旋喷的固

　　淤泥固化仍存在以下几方面问题　　The following problems still exist in sludge solidification　　(1)目前淤泥固化大多是在淤泥含水率较高、 呈流动状态下进行的， 这就意味着要加入较多的固化材料，因此不仅固化效果不佳，而且经济适用性差。　　(1) At present, sludge solidification is mostly carried out under the condition of high moisture content and flowing state of sludge, which means that more solidification materials should be added. Therefore, not only the solidification effect is poor, but also th

　　污泥处理就是对污泥进行浓缩、调治、脱水、稳定、干化或焚烧的加工过程。　　Sludge treatment is the process of thickening, conditioning, dehydration, stabilization, drying or incineration of sludge.　　随着我国经济的发展,城市废水排放量日益增多,污泥产生量也随之大幅度提高,污泥处理处置逐渐成为国内外关注的焦点。　　With the development of China's economy, the discharge of urban wastewater is increasing day by day, and the production of sludge is also greatly improved. Sludge treatment and dispos
