Treatment method for water with high sediment content for micro-irrigation

Abstract

The invention discloses a treatment method for water with high sediment content for micro-irrigation, and belongs to the water treatment field. A specific treatment method comprises the following steps of guiding water from Yellow river to an output channel, reaching an artificially-constructed settling channel through the channel for naturally settling sediment; entering settled water into a water storage tank for storage in an overflow form; naturally settling sediment by a V-shaped weir inside the water storage tank; then, slowly passing through a filter wall for filtering; taking clear water from a water source filtered by the filter wall by a floating barrel after a great deal of sediments and planktons are isolated; and finally, feeding the clear water obtained by the floating barrel into a gravel-laminate filter system for mechanically filtering. Water from Yellow River or similar sediment water treated by adopting the method disclosed by the invention can effectively separate sediment in the water, and can block various inorganic and organic impurities in water, so that the water quality finally reaches requirements of micro-irrigation water quality.

Description

technical field [0001] The invention belongs to the field of water treatment, in particular to the treatment of high-silt water. Background technique [0002] The current water-saving irrigation industry, especially the high-sediment water treatment method for micro-irrigation applications, is not well designed and systematic enough, and often fails to meet the requirements of users. The water quality requirements for agricultural saving irrigation are not met, resulting in blockage of drip irrigation pipe drippers, micro sprinklers, nozzles and other irrigators, shortening the service life of the field saving irrigation system; Relative to the cleanest water, the sediment at the bottom or the floating impurities in the upper part are often brought in, causing secondary pollution of the water quality and increasing the workload of the mechanical filtration equipment; 3. Some plankton in the water and colloids that are difficult to settle naturally Substances can still enter...

Problems solved by technology

[0002] The current water-saving irrigation industry, especially the high-sediment water treatment method for micro-irrigation applications, is not well designed and systematic enough, and often fails to meet the user's requirements. The main shortcomings are: 1. The filtration is not thorough, and the sediment filtration can The water quality requirements for agricultural irrigation are not met, resulting in blockage of drip irrigation pipe drippers, micro sprinklers, nozzles and other irrigators, which shortens the service life of the field irrigation system; Relative to the cleanest water, the sediment at the bottom or the floating impurities on the upper part are often brought in, causing secondary pollution of the water quality and increasing the workload of the mechanical filtration equipment; 3. Some plankton and colloids that are difficult to settle naturally in the water Substances can still enter the filter machinery, which often causes the mechanical filter equipment to be blocked and unable to work or the filter to be backwashed frequently. On the one hand, a large amount of water is wasted, and on the other hand, the amount of irrigation water in the field cannot be guaranteed; Fast, increased dredging investment
