In-situ ecological restoration technology integration system for black and odorous rivers and lakes and control method thereof

Abstract

The invention discloses an in-situ ecological restoration technology integration system for black and odorous rivers and lakes. The system comprises a water purification microbial preparation, a micro-nano plug flow aerator, a stirrer, an ecological grass water purification unit, a nano-filtration water purification unit, a monitoring and controlling center, a sensor unit, a wireless network unit and a solar photovoltaic power station. The water purification microbial preparation is used for absorbing and mineralizing organic carbon and organic nitrogen, chelating heavy metal and immobilizing soluble phosphate. The micro-nano plug flow aerator is used for carrying out water body oxygenation, aeration and plug flow formation and putting the water purification microbial preparation to achieve nanocrystallization of bubbles. The monitoring and controlling center is used for monitoring water quality indexes on line and automatically correcting control commands according to water quality changes. By means of the system, the concept of only treating water in traditional pollution treatment is broken, a breakthrough is obtained, the self-purification capability of rivers, lakes and shallow seas can be rapidly recovered in a short time, a biologic chain system can be activated, a water ecological benign cycle can be formed, and the purpose of treating wastewater fundamentally can be achieved. The invention further discloses a control method based on the in-situ ecological restoration technology integration system for black and odorous rivers and lakes.

Description

technical field [0001] The invention relates to a treatment technology for black and odorous rivers and lakes, and is especially suitable for integrated equipment and control methods for ecological in-situ restoration and treatment of pollution in rivers, lakes, landscape water and shallow seas. Background technique [0002] Due to various comprehensive reasons in the process of rapid social and economic development, a large amount of industrial wastewater, freshwater industry, and domestic sewage without effective treatment are discharged into rivers, lakes, and shallow seas in cities and villages, causing water environmental pollution and eutrophication of rivers and lakes. Melting and black and smelly rivers are common phenomena in my country's urban and rural water environments. Discharge of reclaimed water from sewage plants, human activities, industrial waste water, and agricultural pollution have caused water quality deterioration in rivers, lakes, and shallow seas, an...
