Abstract

The invention discloses a method for treating micro-polluted source water by using a biodegradation flocculation reaction tank, belonging to the technical field of water treatment. The method comprises the concrete steps of (1) enabling micro-polluted source water to enter a mixing tank, adding a coagulant, uniformly mixing, and reacting for 10-30s; (2) enabling effluent of the mixing tank to enter a biodegradation flocculation reaction tank so as to be treated, and reacting for 15-25min; (3) enabling effluent of the biodegradation flocculation reaction tank to enter a sedimentation tank so as to be subjected to solid-liquid separation; (4) enabling effluent of the sedimentation tank to sequentially enter a filter tank and a disinfecting tank and finally enter a water supply network after the water quality is casually inspected to be up to the standard. The method has the beneficial effects that a packing layer in the biodegradation flocculation reaction tank rotates along with a driving shaft to ensure that a biofilm formed by attached microorganisms is in repeated contact with micro-polluted source water, so that low-molecular weight organic matters and ammonia nitrogen in water are degraded, the flocculation efficiency is increased, and the water quality is further improved; in addition, the reaction tank is simple in inner structure, so that the water treatment cost is reduced.

Description

technical field [0001] The invention relates to a technology for treating slightly polluted source water, belonging to the technical field of water treatment, in particular to a method for treating slightly polluted source water in a biodegradation flocculation reaction tank. Background technique [0002] At present, the water quality of nearly 50% of key urban water sources does not meet the water quality standards for drinking water sources, mainly manifested in the state of slightly polluted water source water, that is, the content of organic pollutants in the water increases, and some water quality indicators exceed the "surface water environmental quality standards" Class III water bodies Standards, mainly ammonia nitrogen, permanganate index, chemical oxygen demand, volatile phenols, and biochemical oxygen requirements exceed health standards. In order to ensure that the water quality of the water supply meets the national drinking water quality standard, many advanced...
