Multimedia filter is a kind of filter device that uses one or several kinds of filter media to remove suspended impurities and clarify water through granular or non-granular materials with a certain thickness under a certain pressure. The commonly used filter materials are quartz sand, anthracite, manganese sand and so on.

多介质过滤器系统设置一套加药系统，所加药剂为聚合硫酸铁，聚合硫酸铁有除浊、脱色、脱油、脱水、、除臭、除藻、去除水中COD、BOD及重金属离子等功效显著；加药点设置在多介质过滤器进水母管上设置管道混合器提果。

Multimedia filter system sets up a dosing system, the dosing agent is polyferric sulfate. Polyferric sulfate has remarkable effects on turbidity removal, decolorization, deoiling, dehydration, sterilization, deodorization, algae removal, COD, BOD and heavy metal ions removal, etc. The dosing point is set on the jellyfish tube of multi-media filter to set up a pipeline mixer for lifting. High effect.

针对运行中存在的问题，淄博多介质过滤器公司建议采取以下措施：

In view of the existing problems in operation, Zibo Multimedia Filter Company recommends the following measures:

对原系统进行改造升级。脱硫废水来水浑浊，则要检查脱硫废水系统的运行情况，对脱硫废水处理系统运行进行相应的调整及必要的改造；在设计参数范围内泽达多介质过滤器反洗流量，提高反洗强度，以避免沉淀物残留在滤层中，防止沉淀物和滤料结成硬块。同时考虑增加气洗，保证反洗效果；重新对滤料进行筛分，使粒径分布达到优化；运行时控制流量，压力；非运行时不要将过滤器内水放尽，保留一定高度的水垫层。通过一系列的运行方式的调整，我们找到了一个相对较理想的运行模式，水质改善，达到了回用水水质的标准。

Upgrade the original system. The operation of the desulfurization wastewater treatment system should be checked for the turbidity of the water coming from the desulfurization wastewater, and the operation of the desulfurization wastewater treatment system should be adjusted and revamped accordingly. In the range of design parameters, the backwashing flow rate of Zeda multi-medium filter should be increased, so as to avoid the residual sediment in the filter layer and prevent the sediment and filter material. Caking into lumps. At the same time, consider increasing air washing to ensure the effect of backwashing; re-screen the filter material to optimize the particle size distribution; control the flow rate and pressure during operation; do not drain the water in the filter during non-operation, and retain a certain height of water cushion. Through a series of adjustment of operation mode, we found a relatively ideal operation mode, the water quality improved, and reached the standard of reused water quality.

多介质过滤器设计时，能直接考虑采取无人值守操作方式，一般投运并反洗，方便运行人员操作。在电厂废水处理中，多介质过滤器能够对废水进行预处理，实现水资源的再利用，同时也能带来经济效益。

In the design of multi-media filter, the unattended operation mode can be directly considered. It is generally put into operation and backwashed, which is convenient for operators to operate. In wastewater treatment of power plants, multi-media filters can pretreat wastewater, realize the reuse of water resources, and also bring economic benefits.
