Water-silt separation integrated equipment for Yellow River water

Abstract

The invention discloses water-silt separation integrated equipment for Yellow River water. The water-silt separation integrated equipment comprises a flocculant adder, a booster pump and a water-silt separator. The water-silt separator comprises a shell, a water inlet arranged in the shell, a filter material, a silt separator, a water outlet, a silt discharge port, a material pumping pipe, a material pumping pump connected with the material pumping pipe, a filter material washing pool arranged above the shell, a stirring tank, a flocculate discharge pipe and a silt discharge port, wherein the particle size of the filter material is larger than that of silt in the Yellow River water. Microbial colloids and floccules in the Yellow River water are filtered through the filter material, silt in the Yellow River water is separated through the arrangement of the silt separator, the Yellow River water is treated to meet the drip irrigation requirement, meanwhile, the filter material is recycled through the arrangement of the material pumping pipe, the material pumping pump, the filter material washing pool and the like, the Yellow River water treatment cost is reduced, meanwhile, the treatment efficiency and quality are improved, and guarantee is provided for drip irrigation of the Yellow River water.

Description

technical field [0001] The invention relates to the technical field of Yellow River water irrigation, in particular to an integrated equipment for water and sand separation of Yellow River water. Background technique [0002] The irrigation area of ​​the Yellow River consumes a huge amount of agricultural water. For many years, the extensive flood irrigation method has greatly wasted the precious water resources of the Yellow River. The irrigation water utilization coefficient is only 0.4. If the irrigation water utilization coefficient can reach 0.8, then the agricultural irrigation water will Project can save 2.8 billion m3 of water, which will produce huge social, economic and ecological benefits. In order to tap the potential of agricultural water saving, advanced irrigation methods such as sprinkler irrigation and drip irrigation have been introduced in various irrigation areas along the Yellow River. Drip irrigation is one of the most effective water-saving technologi...

AI Technical Summary

Problems solved by technology

However, the grit chamber combined with a combination of physical filters takes up a large area, with an average single grit chamber occupying an area of ​​20-50 mu. The investment is relatively high, and it is not suitable for large-scale promotion and use.

Secondly, the combined physical filter can only filter solid impurities, and the colloidal microorganisms in the Yellow River water are still difficult to remove, which can easily cause dripper clogging and affect the irrigation effect.
