Description

河湖泊涌污染底泥处理余土再生*** 技术领域  River lake rushing pollution sediment treatment residual soil regeneration system
[0001] 本发明属于水环境治理技术领域, 尤其涉及一种河湖泊涌污染底泥处理余土再 生***。  [0001] The present invention belongs to the technical field of water environment treatment, and in particular relates to a system for regenerating a residual soil in a river and lake.
背景技术  Background technique
[0002] 河涌是一种幵放式水域, 一般具有水面窄、 流程长、 沿海与近海河流多具有感 潮特征等特点, 湖泊是一种相对封闭的水域, 具有水面宽、 水深浅、 水流速度 缓、 水体交换慢等特点, 河湖泊涌一般容易受季节雨汛影响。 随着社会经济的 迅猛发展, 城市人口急剧增多, 面向城市河湖泊涌的排污量大幅度增加, 河湖 泊涌成了各种污染物的汇集场所, 使水体污染日趋严重, 水环境状况日益恶化 , 水质变黑发臭、 鱼虾生存环境急剧恶化或无法生存。 河湖泊涌床底底泥受污 染水体长期侵蚀、 多年沉积形成污染底泥且日益加重, 是影响水环境质量的内 在污染源。  [0002] The river is a kind of open water, generally characterized by narrow water surface, long process, and tidal characteristics of coastal and offshore rivers. The lake is a relatively closed water area with wide water surface, shallow water and water flow. The characteristics of slow speed and slow water exchange are generally affected by seasonal rain. With the rapid development of the social economy, the urban population has increased sharply, and the amount of sewage discharged into urban rivers and lakes has increased greatly. Rivers and lakes have become a gathering place for various pollutants, causing serious pollution of water bodies and deteriorating water environment. The water quality has become black and stinky, and the living environment of fish and shrimp has deteriorated drastically or cannot survive. The bottom sediment of the river and lake bed is polluted by the long-term erosion of the contaminated water body, and the sedimentation of the sediment is formed for many years, which is an intrinsic pollution source that affects the quality of the water environment.
[0003] 在河湖泊涌水环境治理的过程中, 业内逐渐形成需要截断外污染源、 清除内污 染源、 水质净化、 生态恢复四个步骤的共识。 其中, 内污染源就是污染底泥, 由于污染底泥成分复杂、 含水率高, 目前, 国内的底泥处理工艺均为自然或机 械脱水、 材料固化等, 例如, 一种是自然放置, 即将底泥存放于低洼地带进行 自然滤水和干化; 另一种是机械脱水, 底泥经材料调理后, 利用机械设备进行 脱水减量, 然后运输到指定的收纳场所; 又一种是材料固化, 利用稳定剂、 固 化剂等材料添加到污染底泥中, 采用各种搅拌设备拌合均匀、 堆放养护, 养护 完成后运输到指定场所; 再一种是机械脱水固化, 在机械脱水前的调理过程中 , 也同吋添加固化材料, 在脱水减量的过程中同步实现稳定固化。 然而, 经脱 水固化后的底泥只能用于堆放和填埋, 一方面是底泥量大则需要大量空间用来 堆放和填埋, 另一方面无法实现对底泥中泥土的再生利用。 因此, 如何实现污 染底泥处理过程中余土的再生已成为业内亟待解决的技术问题。  [0003] In the process of water and river environment control in rivers and lakes, the industry has gradually formed a consensus that it needs to cut off external pollution sources, remove internal pollution sources, water purification, and ecological restoration. Among them, the internal pollution source is the contaminated sediment. Due to the complex composition of the contaminated sediment and high water content, at present, the domestic sediment treatment process is natural or mechanical dehydration, material solidification, etc., for example, one is naturally placed, and the sediment is about to be sedimented. Stored in a low-lying area for natural water filtration and drying; the other is mechanical dewatering. After the material is conditioned, the sediment is dewatered and reduced by mechanical equipment, and then transported to a designated storage place.
