基于风光互补发电的湖泊水质监测与治理综合利用系统研究OA

With the acceleration of industrialization and urbanization,the problem of lake pollution is becoming increasingly severe,and due to the difficulty of having electricity supply from the power grid around the lake,it poses serious constraints on water quality monitoring and remediation.This paper proposes a comprehensive utilization system for lake water quality monitoring and remediation based on wind-PV complementary power generation(hereinafter referred to as"comprehensive utilization system"),which mainly consists of three modules:wind-PV complementary power generation module,sewage comprehensive remediation module,and water quality monitoring and treatment module.Firstly,a brief introduction is given to this comprehensive utilization system.Then,the design schemes of the three major modules of this comprehensive utilization system are elaborated,and the chemical agent delivery rate and water pump head in the drainage system are calculated.Finally,the theoretical and physical models of this comprehensive utilization system are constructed,and its water quality monitoring and treatment effects are verified through tests in a local water area.The research results show that:1)The comprehensive utilization system solves the limitations and intermittency of single energy supply by complementing PV power generation with wind power generation,achieves day night complementary power supply and off-grid power supply,and improves the stability of power supply by configuring batteries.2)Real time dynamic monitoring and purification treatment of water quality parameters have been achieved.Significantly reduced the risk of secondary pollution and achieved intelligent linkage between chemical agents and ecological restoration technology.A full chain governance system of"monitoring-treatment-restoration-monitoring"has been formed,significantly improved the efficiency of lake remediation and the speed of ecological restoration.3)The local water area testing of the physical model confirmed that the wind-PV complementary power generation module can provide the electricity required by all loads of the comprehensive utilization system.The water quality monitoring and treatment module can achieve automatic monitoring of water quality parameters,and the effect of water purification treatment is relatively ideal.The comprehensive utilization system deeply integrates new energy generation technology,automation control technology,and ecological governance and restoration technology,which can reduce the use of traditional energy and lower labor costs,achieve more accurate water quality monitoring and remediation,and thus improve the efficiency of lake remediation.It can promote sustainable management of water resources and green transformation of regional economy,with significant ecological,economic,and social benefits.
