Embodiment Construction

[0046] The inland river in a certain city is 15-40 meters wide and 2-5 meters deep. It is a black and smelly river, and it is inferior to the V-class water quality standard. Although sewage interception pipe network projects have been implemented on both sides of the river, there is still a small amount of domestic water and domestic garbage discharged into the inland river from time to time, causing total phosphorus and ammonia nitrogen to exceed the standard. Its main water quality indicators are shown in the table below.

[0047] The vertical immersion type water quality in-situ purification curtain shown in the present invention is used to treat the river course. In the narrowest part of the upstream and middle reaches of the river section, the interception type vertical immersion type water quality in-situ purification curtain screen equipment is used, which is formed by three sets of screen fans with a width of 5 meters across and in parallel. Floating objects such as...

Abstract

The invention provides a vertical immersed type in situ water quality purification curtain screen and belongs to the field of water treatment equipment. The vertical immersed type in situ water quality purification curtain screen is mainly characterized in that the curtain screen is mainly composed of a grid system, a curtain screen purification unit, a motor transmission system and a supporting system; the grid unit is composed of grids constituted by mesh holes, grid teeth, grid tooth front hooks and side end hinge hanging teeth; the curtain screen purification unit is composed of screen door purification modules constituted by water quality purification multifunctional curtain production screen cores, side end movable hinges and peripheral screen frames; the motor transmission screen can drive the grid unit to move vertically and can drive the curtain screen purification unit to move in the horizontal direction; the work mode of the curtain screen is that the curtain screen is vertically immersed in raw water to be treated; the curtain screen has the function of in situ water quality purification. The vertical immersed type in situ water quality purification curtain screen has the advantages of being wide in application range, good in water quality purification effect, easy to operate and maintain, stable in performance after long-term operation and environmentally friendly.

Description

technical field [0001] The invention relates to an upright submerged water quality in-situ purification curtain, which belongs to the field of water treatment equipment, and is especially suitable for water environment treatment, drinking water pretreatment, water treatment under the conditions of large flow, low pollutant concentration and slow flow velocity. Safety emergency treatment and advanced treatment of sewage / wastewater. Background technique [0002] The overall situation of the current water environment quality is not optimistic, and the problem of water pollution is still prominent. According to the "2014 Bulletin on the State of the Environment in China", 968 state-controlled surface water monitoring sections (points) in 423 major rivers and 62 key lakes (reservoirs) across the country have carried out water quality monitoring. Sections accounted for 20.9%, 6.8%, and 9.2% respectively, and the main pollution indicators were chemical oxygen demand, total phospho...
