A systemic water treatment device and method

Abstract

The invention provides a water body systemized treatment device and method. The device comprises a water inlet pipe, a pretreatment unit, a connecting pipe, a depth treatment unit and a water outlet pipe, which are sequentially connected. The pretreatment unit is used for separating liquid from solid in water for physical refined filtering. The depth treatment unit is used for degrading catalytic and oxidized organics in water and disinfecting and sterilizing for deep purification. The method uses the water body systemized treatment device to treat water. The water body systemized treatment device is scientific and reasonable in structure, good in purification effect and low in manufacturing and operation cost, and water treated by the device and method can be directly used for drinking.

Description

technical field [0001] The invention relates to water treatment equipment and technology, in particular to a systemic water treatment device and method suitable for water solid-liquid separation, removal of organic matter, disinfection and sterilization, and algae treatment. Background technique [0002] As we all know, for water system treatment, it mainly includes pretreatment and deep purification. Solid-liquid separation in water, removal of organic matter, disinfection and sterilization, and algae treatment are always a core technical issue in the industry. A large amount of chemical agents, ozone or ultraviolet radiation are used to achieve, and secondary pollution and side effects are common. In the process of water purification, the use of chlorine gas as an oxidant for disinfection and sterilization has its fatal weakness, that is, it will generate intermediate products such as chloroform, chloroethane, carbon tetrachloride and other chlorine-containing organic comp...

Problems solved by technology

It is difficult to recover the catalyst of the suspension system reactor and it is difficult to apply it on a large scale. The fixed structure mostly adopts carrier coating or smearing, which has the problems of small contact surface area and low efficiency.

Japanese Patent Ping 4-141294 uses porous sintered material or optical fiber as a catalyst carrier to increase the surface area, but a large part of the light cannot be irradiated, and the price is expensive and impractical

Chinese invention patent 95244568 discloses a fixed-film photocatalytic oxidation water quality deep purifier, Chinese invention patent 96251030 discloses a photocatalytic water quality processor, and invention patent CN1257838 discloses continuous photocatalytic purification of wastewater containing organic pollutants and drinking water method and equipment, which uses a suspension system to achieve continuous processing, but it is difficult to achieve high-capacity and high-efficiency processing

The water treatment equipment in the prior art has the following common disadvantages: (1) an additional stirrer is required to increase the pollution source, noise, and failure rate; (2) the reaction time is long, and it is difficult to achieve continuous treatment; (3) the catalyst carrier, It is difficult to seal the lamp protection tube and the upper and lower ends; (4) the processing capacity is small and the expansion is difficult; (5) the main consideration is to increase the overall efficiency by increasing the catalyst carrier area and improving the activity of the catalyst, which restricts the large-scale development of large capacity ; (6) Complex structure, inconvenient for installation and maintenance
