The invention relates to the technical field of
water treatment equipment, and concretely relates to a multi-stage
water treatment device. The device comprises a three-way
pipe body, a water inlet formed in the upper side of the three-way
pipe body, a first water outlet and a second water outlet, and the first water outlet and the second water outlet are formed in the lower sides of the two ends of the three-way
pipe body respectively and communicate with the water inlet. Two L-shaped
sewage storage pipes are detachably installed on the lower side of the three-way pipe body, two multi-stage filtering pieces are arranged between the first water outlet and the second water outlet of the three-way pipe body and used for conducting multi-stage filtering on a
water source, the filtering effect is good, the two L-shaped
sewage storage pipes are connected to the lower side of the three-way pipe body through flanges, the two L-shaped
sewage storage pipes are arranged between the two multi-stage filtering pieces respectively, and are respectively used for precipitating impurities and sewage filtered by the
multiple stages of filtering parts, the
water source can be effectively shunted, the two multi-stage filtering parts are arranged between the first water outlet and the second water outlet and used for multi-stage filtering of the
water source, the filtering effect is good, and the impurities and the sewage can be directly precipitated in the L-shaped sewage storage pipes and discharged conveniently.
