Description
技术领域 technical field
本实用新型涉及一种废水处理系统，尤其是涉及造纸污水深度处理系统。 The utility model relates to a wastewater treatment system, in particular to an advanced treatment system for papermaking wastewater.
背景技术 Background technique
我国每年排放的污水量很大，经处理后排放的又不多，对环境造成很大破坏，我国各大水系都产生不同程度的污染，水环境严重恶化。长期以来，造纸废水一直是制约纸业快速发展的问题之一，造纸废水中污染物浓度高，成分较复杂，含有大量的造纸原料和化学药品，耗氧严重，致使造纸废水处理困难，成为严重污染环境的行业之一。如果造纸废水直接排出会严重污染环境，所以必须经过净化处理。而废纸造纸废水中的悬浮物SS及化学需氧量COD浓度较高，COD则由非溶解性COD和溶解性COD两部分组成，通常非溶解性COD占COD组成总量的大部分，当废水中SS被去除时，绝大部分非溶解性COD同时被去除。因此，废纸造纸废水处理要解决的主要问题是去除SS和COD，现有技术造纸废水系统中主要采用生物氧化脱色池内放置固定填料来降解废水中致色物质及悬浮物SS，这种处理池脱色效果不明显，不能有效降解水中致色物质，水中的有机物去除率低，处理后的废水泡沫现象严重，出水色度深，不能去除高浓度污水的色度，COD去除率低，污水的可生化性低,废水中的COD常常超标排放。 The amount of sewage discharged in our country is very large every year, and the amount discharged after treatment is not much, which has caused great damage to the environment. All major water systems in our country have produced varying degrees of pollution, and the water environment has seriously deteriorated. For a long time, papermaking wastewater has been one of the problems restricting the rapid development of the paper industry. The concentration of pollutants in papermaking wastewater is high, the composition is relatively complex, it contains a large amount of papermaking raw materials and chemicals, and the oxygen consumption is serious, which makes the treatment of papermaking wastewater difficult. One of the industries that pollute the environment. If the papermaking wastewater is directly discharged, it will seriously pollute the environment, so it must be purified. However, the concentration of suspended solids SS and chemical oxygen demand COD in waste paper and papermaking wastewater is relatively high, and COD is composed of insoluble COD and soluble COD. Usually, insoluble COD accounts for the majority of the total COD composition. When SS is removed from wastewater, most of the insoluble COD is removed at the same time. Therefore, the main problem to be solved in the treatment of waste paper and papermaking wastewater is to remove SS and COD. In the prior art papermaking wastewater system, fixed fillers are mainly placed in the biological oxidation decolorization tank to degrade the color-causing substances and suspended solids SS in the wastewater. This treatment tank The decolorization effect is not obvious, and the color-causing substances in the water cannot be effectively degraded. The removal rate of organic matter in the water is low. The biochemical property is low, and the COD in the wastewater is often discharged beyond the standard.
