Problems solved by technology
The existing coagulation technology is used in the water treatment process unit, and specific structures need to be set up. Because the application of this technology must ensure the necessary and sufficient mixing and flow of the water body, so that the added chemicals are evenly mixed. In addition, if the coagulation and phosphorus removal method is used, it will also It is necessary to meet the flow field conditions required by coagulation dynamics. Therefore, for natural large water deep water bodies such as water source reservoirs and lakes, it cannot be applied without effective mixing methods and flow field conditions required by coagulation dynamics.

Embodiment Construction
[0023]The idea of the present invention to solve the above-mentioned problems is to install an enhanced chemical phosphorus removal non-powered automatic quantitative water quality improvement device in the installation hole of the pumping aerator, the pumping aerator is at the bottom, and the non-powered automatic adding water quality improving device is at the top, using a horse According to the principle of the bottle, the constant pressure regulator tube is used to transmit the atmospheric pressure, and the liquid medicine stored in the upper liquid medicine storage tank is transported to the bottom liquid medicine storage chamber through the liquid medicine delivery pipe. When the pumping water aerator is running, when the air chamber is filled with air, the gas in the air chamber is released instantly, forming a large air bomb in the guide tube, and quickly floats up, driving the water body in the cylinder body to flow upward, and driving the propeller to rotate While r...

The invention discloses a water-lifting-aeration-based water quality improving device with enhanced chemical phosphorus removal and unpowered automatic quantified addition functions, which comprises an unpowered adding device that is vertically arranged on a water-lifting aerator sealing bin, and an automatic quantified adding device that is arranged in water-lifting aerator barrel by an installing hole, wherein the unpowered adding device comprises an upper liquid medicament storage box, a constant-voltage stabilivolt, a horizontal liquid medicament transmitting pipe, a vertical liquid medicament transmitting pipe and a liquid medicament transmitting pipe fixing frame, and the automatic quantified adding device comprises a push-type propeller, a liquid medicament releasing cone-shaped switch, a bottom liquid medicament storage cavity, a connecting sleeve, a liquid medicament leakage-preventing device and a limiting pin, so that passivation and stabilization of pollutants can be realized, and phosphorus and other pollutants in bottom sediment can be inhibited from releasing and spreading to water. The device has the advantages of being compact in structure, flexible in use, free from external power, convenient to install, easy to combine with a water-lifting and aeration technology, small in project investment, powerful in function and the like.
Description
technical field [0001] The invention belongs to the technical scope of water environment treatment, and relates to a water quality improvement device for inhibiting the release of phosphorus from lake and reservoir sediments and simultaneously short-term emergency removal of high-load phosphorus content in large water and deep reservoirs. Water quality improvement device with automatic quantitative dosing of power. Background technique [0002] At present, most cities in my country have or are gradually using surface water such as reservoirs and lakes as the main water supply sources for cities. Water sources such as lakes and reservoirs play a very important role in urban water supply in my country. Problems such as eutrophication in urban areas have become increasingly prominent, which not only directly affects the water quality safety of urban drinking water and the sustainable use of urban water sources, but also greatly increases the cost of water treatment. Reservoirs ...
