Description

technical field [0001] The invention relates to a water body purification system, more specifically, to a water discharge recyclable ecological pond purification system. Background technique [0002] my country has long faced the pressure of water pollution, water resource shortage, water ecological degradation, and flood disasters, and water pollution has exacerbated the deterioration of the other three water problems to a certain extent. Although measures have been taken in recent years Certain control measures have achieved some results, but overall, my country's water pollution will still be a key factor restricting the sustainable development of the economy and society for a long time to come. The Taihu Lake area has a superior geographical location and a pleasant climate. It is one of the areas with the most developed economy, the most densely populated and the highest degree of urbanization in China. However, we must see that the water environment problems in the Taih...
