Flow guide wall device, water quality purification treatment system and method thereof

Abstract

The invention discloses a flow guide wall device, a water quality purification treatment system and a method thereof. The flow guide wall device comprises a framework assembly and a filling assembly.A gap is formed in the side wall of the framework assembly, the framework assembly is further provided with an accommodating groove communicated with the gap, and the filling assembly comprises a filter layer and a phosphorus removal filter material layer. The filter layer and the phosphorus removal filter material layer are both arranged in the accommodating groove, and the phosphorus removal filter material layer is positioned on the upper part. The water quality purification treatment system comprises a plurality of flow guide wall devices, and the flow guide wall devices are arranged on revetments on the two sides in the water flow direction of a to-be-treated water area at intervals so that water flows circuitously. According to the flow guide wall device, the water quality environment state does not need to be changed manually, the purification efficiency is high, and when sewage in a to-be-treated water area flows through the framework structure, the purpose of nitrogen and phosphorus removal is achieved in a biophysical combination mode. The flow guide wall device can achieve the purposes of no energy consumption, high purification rate, wide application range and multifunctional phosphorus element reduction measures.

Description

technical field [0001] The invention relates to the field of water ecology, in particular to a diversion wall device, a water purification treatment system and a method thereof. Background technique [0002] An appropriate amount of nitrogen and phosphorus plays an important role in promoting the growth of aquatic plants and microorganisms, and also plays a certain role in maintaining the balance of the water environment. However, excessive nitrogen and phosphorus and other nutrients entering the water body will cause eutrophication of the water body and make the water body The phytoplankton in the water proliferates in large numbers, even explosively, and produces the phenomenon of "water bloom". The content of nitrogen and phosphorus in water body is an important indicator to monitor the quality of water. Phosphorus seeps into the soil, mainly through fertilizers, and then leaks into water bodies in stormwater and snowmelt runoff. [0003] With the rapid economic develop...

AI Technical Summary

Problems solved by technology

In terms of phosphorus removal efficiency, the biological phosphorus removal method cannot treat phosphorus to a low concentration. The first reason is that the ability of microorganisms to decompose organic phosphorus is limited, and the second is that phosphorus residues in microorganisms will excrete phosphorus due to metabolism.

[0010] The existing technology mainly has the following problems: 1) The purification effect is unstable, and special personnel are required for on-site maintenance; 2) It is difficult to add chemicals manually and accurately in large lakes; 3) Adding chemical flocculants can improve the purification efficiency, but there are residual metal ions, The risk of secondary pollution; 4) The hydraulic flow direction cannot be controlled, and it is easy to form a dead angle of water flow
