Ecological floating bed for water treatment

Abstract

The invention discloses an ecological floating bed for water treatment. The ecological floating bed comprises an outer floating ring, wherein load regulating centers are arranged on the upper side andthe lower side in the outer floating ring; an aeration device is arranged at the center in the outer floating ring; a cover plate is arranged at the upper part of the aeration device; a water outletpipe is arranged at the center in the aeration device; lift pumps are arranged on the left side and the right side of the water outlet pipe; a water-stop sheet is arranged at the lower part of each lift pump; water injection nozzles are arranged at the upper part of the aeration device in a surrounding manner; ecological floating bed units are arranged at the joint of the outside of the aeration device and the outer floating ring; an outer frame is arranged outside each ecological floating bed unit, hooks are arranged in the ecological floating bed units, emergent plant layers surround the outsides of the hooks, weight blocks are arranged on the left side and the right side of the adjacent ecological floating bed units, stabilizing coils are arranged between the adjacent ecological floating bed units, and a floating plant layer is arranged in the center of the adjacent ecological floating bed units. The ecological floating bed for water treatment is simple in structure and has practical functions.

Description

technical field [0001] The invention belongs to the technical field of water body purification, and in particular relates to an ecological floating bed for water treatment. Background technique [0002] With the continuous improvement of human life, the eutrophication of water bodies, ammonia nitrogen, phosphorus and other nutrient salts, and the step-by-step improvement of the National Environmental Protection Agency's sewage discharge standards, the traditional "primary treatment" and "secondary treatment" water treatment technology has been used for many years. And equipment, it has been difficult to adapt to the treatment requirements of today's high turbidity and high concentration sewage, and the treatment process is long, the system is huge, and it also emits a lot of odor. If operators want to meet the latest discharge standards, they need to invest a lot of money to expand the original sewage treatment system, increase the use of land area, high sewage treatment equ...

[0002] With the continuous improvement of human life, the eutrophication of water bodies, ammonia nitrogen, phosphorus and other nutrient salts, and the step-by-step improvement of the National Environmental Protection Agency's sewage discharge standards, the traditional "primary treatment" and "secondary treatment" water treatment technology has been used for many years. And equipment, it has been difficult to adapt to the treatment requirements of today's high turbidity and high concentration sewage, and the treatment process is long, the system is huge, and it also emits a lot of odor

If operators want to meet the latest discharge standards, they need to invest a lot of money to expand the original sewage treatment system, increase the use of land area, high sewage treatment equipment and high post-maintenance costs. However, the traditional sewage depth Treatment of regeneration and reuse technology systems (such as activated carbon filtration, microporous filtration, permeable membrane purification and other technical systems) has high investment and high post-maintenance and operation costs, which are unaffordable for too many operators

The aeration and filtration of the existing river water treatment equipment are treated separately, and the implementation process of the aeration and filtration process is complicated and expensive
