Abstract

Disclosed is an ozone pre-oxidation water treatment method. The water inlet quantity of a first water inlet (6) and the amount of ozone outputted by an ozone diffuser (9) are controlled by an electric control unit (10), so that water within a range with ozone concentration of 0.8-0.9 milligram per liter and the ozone within the range are oxidized for 5 minutes, the electric control unit (10) controls stirring of a first adjustable stirrer (19) and the vibration strength of an ultrasonic vibration array (20) to perform one-minute continuous stirring and vibration according to the water inlet quantity of a second water inlet (16), a second adjustable stirrer (22), a third adjustable stirrer (23) and a fourth adjustable stirrer (24) perform stirring for 15 minutes, reactants are conveyed to a precipitating portion (4) and precipitated for 35 minutes, and the water entering a filtering portion (5) passes a filtering layer (34) and then is drained from a fifth water outlet (33).

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to the technical field of purifying slightly polluted drinking water sources, in particular to an ozone pre-oxidation water treatment method. Background technique [0002] In recent years, due to the discharge of a large amount of domestic sewage, industrial wastewater, and agricultural, fishery and animal husbandry water, most water bodies have been polluted to varying degrees, which has seriously affected urban water supply. Due to the discharge of industrial sewage, the increase in the use of agricultural chemical fertilizers, especially the extensive application of fishery feeds, has caused a large loss of nitrogen and phosphorus nutrients. The degree of eutrophication of lakes is becoming more and more serious, which has become a prominent environmental pollution problem. The lake surface around the water intake of the city is surrounded by a large amount of algae, whi...
