[0002] In a water treatment system using an activated carbon filter, the main function of the activated carbon filter is to absorb organic matter and oil in the water, and at the same time filter and retain large particles of impurities such as other suspended solids. The surface of the activated carbon particles forms a layer of balanced surface concentration. The total surface area of ​​activated carbon particles has an impact on the adsorption capacity, and its adsorption capacity is proportional to the water contact area. The adsorption capacity of activated carbon will be weakened to varying degrees after a long time of filtration, and the adsorption effect will also decrease accordingly; Clean by methods such as stirring cleaning, water backwashing, but, existing cleaning method has the following defects: (1) stirring type cleaning method is easy to leak, energy consumption is high, wearing parts are many, and activated carbon filter material is easily damaged; ( 2) For the intercepted matter attached to the surface of the activated carbon filter material, water backwashing can only elute a large part of it but not all of it; (3) Water backwashing cannot remove various substances adsorbed in the micropores of activated carbon. Pollutants, so that in most cases, the activated carbon filter material that absorbs impurities such as organic matter and reaches saturation can only be discarded due to the loss of adsorption capacity; (4) The backwash time is long, the water consumption is large, the power consumption is large, and waste resource

[0003] Since there is no simple and reliable means to thoroughly clean the activated carbon at present, the intercepted substances that cannot be removed after long-term operation will accumulate in the activated carbon filter material. Once the accumulation of impurities causes the activated carbon to be saturated, the filter material can only be replaced with a new one.

However, the processing of activated carbon has a great impact on the environment, and the market price is relatively high. Frequent replacement of activated carbon filter materials will not only greatly increase the operating cost of the water treatment system, but also be detrimental to the environment; In the process of approaching adsorption saturation, the effluent quality of the water treatment system will also deteriorate
