The invention relates to a fully-automatic intelligent combined environmentally friendly water treatment prizing device. A prizing base is provided with one or combination of two or more of an efficient composite ceramic particle/ceramsite filter, an efficient composite carborundum filter and a novel metal membrane filter, different filters are communicated through a sewage-in-out system, and sewage discharging systems are arranged at the bottoms of the filters respectively; a PLC automatic control system comprises a pneumatic butterfly valve, a pressure gage, a sampling valve and a sewage discharging valve which are connected with the filters, and the PLC automatic control system is used for controlling the sewage-in-out system and a back washing system; configuration of the variety, number and group count of the filters is determined according to the analysis result of ingredients, the content and the physico-chemical property of the quality of the treated water and the water quality pretreatment index requirement. By means of the fully-automatic intelligent combined environmentally friendly water treatment prizing device, hardening and leakage of filler of the filters are avoided, the water quality index requirements of formation water for flooding reservoir, outwards-discharged water and drinking water for residents can be reached stably, land for production is greatly saved, and labor intensity is lowered.
