Embodiment 1
[0092] A low-consumption and high-efficiency intelligent control type anti-clogging constructed wetland rain pollution enhanced treatment system, the steps are:
[0093] After the sewage enters the integrated artificial wetland coupling system from the left,
[0094] 1) Firstly, the SS and some pollutants are intercepted and degraded through the action of the floating leaf and submerged plant modules in the integrated filtration and heating system (the excess SS is deposited by gravity and collected near the valve of the emptying pipe);
[0095] 2) Then obtain a certain temperature through the heating of the heating plate system at low temperature, and then enter the integrated enhanced aeration treatment system, and further reduce pollutants through its aeration and bio-augmented filler system;
[0096] 3) Through the overflow into the integrated artificial wetland system (the temperature in the system is further raised by the action of the middle heating plate), the pollutan...

Abstract
The invention discloses an intelligent-control type antiblockage artificial wetland rain and sewage enhanced disposal system and method based on solar power. The system includes a solar power supply intelligent control system and a sewage disposal main system; the sewage disposal main system consists of an artificial wetland system, an aeration filler system and a filtering, sand settling and heating system which are arranged from inside to outside in sequence. The filtering, sand settling and heating system includes a first box body, a bidirectional water distribution pipeline used for waterdistribution in a filtering area and a heating component; the area between the first box body and the aeration filler system is separated into the filtering area on the upper portion and a preheatingsand settling area on the lower portion, and the preheating sand settling area is communicated with the interior of the aeration filler system. The heating component is used for heating sewage in theartificial wetland system in the preheating sand settling area, and the solar power supply intelligent control system supplies power to the heating component and controls the heating component. By means of the intelligent-control type antiblockage artificial wetland rain and sewage enhanced disposal system and method, energy consumption for running of artificial wetlands is reduced, blockage is prevented, the hydraulic retention time is shortened, the effect is enhanced at the same time, and a great running effect under low temperature is ensured.
Description
technical field [0001] The invention relates to the treatment technology of rainwater, sewage and rain-sewage mixed-flow wastewater, especially the ecological restoration technology of polluted surface water, domestic sewage treatment technology and the field of agricultural non-point source pollution control. Construction and operation of wetland rainwater treatment system. Background technique [0002] In recent years, constructed wetlands have gradually gained continuous research and relatively extensive engineering applications in sewage treatment, especially in domestic sewage treatment, restoration of polluted surface water such as rivers, lakes and other water environments, and treatment of non-point source pollution such as initial rainwater . [0003] However, there are also the following major problems in the operation of constructed wetlands, which affect their further promotion: [0004] 1) From the perspective of constructed wetlands operating at home and abro...
