Phosphorous and turbidity removal system and method for tidal river black and odorous water bodies

Abstract

The invention discloses a phosphorous and turbidity removal system for tidal river black and odorous water bodies. The system comprises an upstream water quality monitoring system, a pretreatment system, a precipitate treatment system, a water quality conservation area, a downstream water quality monitoring system and a control and command center from the river upstream to the river downstream sequentially. The control and command center is respectively connected with the upstream water quality monitoring system, the pretreatment system and the downstream water quality monitoring system. The invention further provides a phosphorous and turbidity removal method for tidal river black and odorous water bodies; the method includes the steps of monitoring water quality of the upstream and the downstream, determining feed quantity through the control and command center automatically, feeding phosphorous separating and algae controlling agents, treating precipitates and the like. The phosphorous and turbidity removal system and method for tidal river black and odorous water bodies has the advantages of low investment cost for building, low cost for operation management and operational simplicity, is economical and adaptable to treatment of tidal river black and odorous water bodies, can remove phosphorous in the water bodies effectively, can reduce turbidity of the water bodies to improve transparency of the water bodies.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a phosphorus and turbidity removal system and method for black and odorous water bodies in tidal rivers. Background technique [0002] On November 24, 2016, it was proposed to vigorously remediate black and odorous water bodies in cities, and to implement basin and regional total control of total phosphorus and total nitrogen in water areas exceeding the standard. It is required to adapt measures to local conditions, one policy for one river, control sources and intercept pollution, and control endogenous pollution in a multi-pronged manner to scientifically remediate black and odorous water bodies in cities. This project thoroughly implements the scientific concept of development, strives to improve ecological civilization, and effectively solves the outstanding water problems that harm the public's health. [0003] In November 2015, Shenzhen issued the "Shenzhen Water...

AI Technical Summary

Problems solved by technology

[0005] The methods for removing phosphorus from river water include 1) chemical method: spraying coagulant or adsorbent, the effect is obvious; 2) physical method: such as dredging the bottom mud, the cost is high, and it may also lead to the destruction of the nitrogen and phosphorus balance of the water body and the deterioration of the water quality; ③Biological methods: For example, water hyacinth and other aquatic weeds are stocked in waters, but their vicious reproduction is easy to cause secondary pollution

[0006] At present, in many river water phosphorus removal methods, there are disadvantages such as ineffective phosphorus removal and high phosphorus removal cost.
