Embodiment Construction

[0017] The present invention will be further elaborated and illustrated below in conjunction with the drawings and specific embodiments. The technical features of the various embodiments of the present invention can be combined accordingly without conflict with each other.

[0018] Such as figure 1 , 2 As shown, the flow-limiting variable phosphorus removal reactor body is divided into water inlet zone I, reaction zone II and sedimentation zone III sequentially from bottom to top. The bottom of water inlet zone I is a funnel-shaped sludge bucket 2, and sludge bucket 2 There is a slag discharge port 1 at the bottom, and an aeration pipe 3, a water inlet pipe 4 and a medicine pipe 5 are arranged above the slag discharge port 1, and the outlets of the three pipelines pass through the outer wall of the reactor and enter the inner cavity of the water inlet zone I; Zone II is in a straight cylindrical shape, and there are several mud outlets 8 on the outer wall; the bottom of the react...

Abstract

The invention discloses a current-limiting variable phosphate-removing reactor and a method for removing phosphate in waste water. A reactor body comprises a water inlet zone, a variable reaction zone and a settling zone respectively from down to up, a slag removal opening and a sludge bucket are arranged at the lower part of the water inlet zone, an inlet pipe, an aeration pipe and a drug inlet pipe are arranged in the water inlet zone, a control flange, a support separation net, a sludge removal port, and a backflow port are arranged in the variable reaction zone; and an overflow port, an outlet pipe and a back flow pipe are arranged in the settling zone. The method combines flocculation, adsorption, filtering, crystallization for phosphate removing, and combines phosphate removing and phosphate storage; the functions of each unit is complementary, the structure is compact, the land occupation area is little; the reaction zone is adjustable, the operation is flexible; the biological sludge is taken as a medium, waste can be used for treating waste, and the method has large reutilization potential.

Description

Technical field [0001] The invention relates to a reactor for treating phosphorus-containing wastewater, in particular to a flow-limiting variable phosphorus removal reactor and its wastewater phosphorus removal method. Background technique [0002] Phosphorus is the main limiting factor for the eutrophication of water bodies, but it is also an essential nutrient element for the growth and reproduction of organisms. Excessive discharge of phosphorus-containing wastewater generated in the production process of human life to water bodies can easily cause eutrophication of the water body, destroy the ecological balance, and adversely affect human life activities. Therefore, the removal of phosphorus from wastewater can control the eutrophication of water bodies from the source. On the other hand, with economic growth and intensified production, people's demand for phosphorus is increasing. According to reports, the world's known phosphate rock resources can only be maintained for a...
