Problems solved by technology

Chlorine dioxide is difficult to solve the problem that a large number of algae die and deposit on the bottom of the water, and are decomposed by microorganisms to consume dissolved oxygen in the water, resulting in water deterioration.
The physical method is time-consuming and labor-intensive, and the efficiency is very low; although the chemical method is quick, if the dosage is not well controlled, it is easy to cause secondary pollution; the conventional biological method has large investment, difficult operation, low algae removal efficiency, and is not suitable for large-scale water governance

Abstract

Disclosed are an ozone pre-oxidation water treatment device and a water treatment method thereof. The device comprises an ozone pre-oxidation reaction portion (1), a mixing portion (2), a condensation portion (3), a precipitating portion (4) and a filtering portion (5), original water to be treated from a first water inlet (6) is oxidized by an ozone diffuser (9) in a fluid channel (11), the ozone diffuser (9) is provided with an embedded gas flow meter (14) capable of setting air intake flow, an electric control unit (10) controls rotating speeds of a second adjustable stirrer (22), a third adjustable stirrer (23) and a fourth adjustable stirrer (24) of the condensation portion (3) according to the water inlet quantity of a third water inlet (21), the water passing the condensation portion (3) is conveyed to the precipitating portion (4) from a third water outlet (39) through a fourth water inlet (27), and the precipitated water is conveyed to a filtering layer (34) of the filtering portion (5) from a fourth water outlet (28), filtered and then outputted 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 purification of slightly polluted drinking water sources, in particular to an ozone pre-oxidation water treatment equipment and a water treatment method thereof. 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...
