Harmful substance removal method from pineapple irrigation water

Abstract

The invention belongs to the field of pineapple cultivation methods and relates to a method for getting rid of hazardous substances of pineapple irrigation water quality. The method is characterized in that a middle-high pressure membrane reverse osmosis water treatment system and the process flow are adopted, natural water is introduced and enters a high efficiency fiber filter for filtration and is then filtered by a stainless steel bag type filter, and then enters an ultrafilter for filtration after pH adjustment, is pumped by a high pressure pump and then enters a reverse ososis water purifier, the softened water after treatment enters a water tank. According to the process requirement, the effulent amount is 10M<3> / h; after the same continuous treatment for twice, the effulent quality reaches HBO2<-> less than 1 milligram / L. The softened water treated by the invention can reach HBO2<-> less than 1 milligram / L. By using the treated softened water to irrigate pineapples, the transplantation survival rate reaches 99 percent.

Description

technical field [0001] The invention belongs to the field of flower cultivation methods; in particular, the field of pineapple cultivation methods. Background technique [0002] Ornamental pineapples are monocotyledonous plants. Most species have extremely short stems, long and narrow leaves, sword-shaped or ribbon-shaped, and are arranged longitudinally at the base of the stems. The bases of the leaves are tightly embracing each other, and the apex of the leaves stretches around, like a blooming lotus flower, forming a small water cup-shaped groove at the bases. The flowers are pulled out from the center of the rosette, the buds are obvious and full, the colors are bright and rich, and the shapes are different, which is the main ornamental part. [0003] Bromeliaceae has a wide variety of plants, with 42 genera and more than 3,000 species, many of which are ornamental plants. The leaves or bracts of ornamental pineapple are colorful, including red, yellow, green, pink, br...
