Example Embodiment

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments. While the present invention will be described in conjunction with preferred embodiments, it should be understood that the invention is not intended to be limited to such embodiments. On the contrary, the invention is to cover alternatives, modifications and equivalents, which may be included within the scope of the invention as defined by the appended claims.

[0022] see Figure 1 to Figure 2 As shown, the present invention is based on the phenomenon of the enrichment of organic matter in the cold trap 1 (or the cold water water pool at the bottom of the water body 7 or the deep pool for short) found by the applicant in practice, especially the low temperature water body in the deep pool can be relatively The long-term stable existence makes this low-temperature water body an important system for enriching most of the substances that cause eutrophication ...

Abstract

The invention discloses a water eutrophication managing cold trap and managing method for shallow lakes. A cold trap keeping low temperature of the water is arranged at the bottom of the shallow water; and a water outlet of the cold trap is located below the water surface. The managing method comprises the following steps of: 1) setting a cold trap at the bottom of the shallow water; 2) keeping the water temperature in the cold trap at 3-10 DEG C through the ambient temperature or refrigeration equipment; and 3) enriching organic matters in the water at low temperature of the cold trap. The invention has the beneficial effects that: as multiple harmful substances of water are enriched in the water with a relatively low temperature due to relatively low solubility at a relatively low temperature or other reasons, the harmful substances in the water are cleared away or reduced. Harmful substances enriched in a deep pool or cold trap are disposed.

Description

technical field [0001] The invention relates to a cold trap and a method thereof, more specifically, to a cold trap and a method for treating eutrophication of water bodies such as shallow lakes. Background technique [0002] At present, the commonly used water pollution control methods at home and abroad are activated sludge and aeration, biofilm, and oxidation methods, while the treatment methods for large water bodies such as lakes and rivers generally include physical methods (water transfer dilution\silt cleaning\clay covering ), chemical methods (chemical reagent precipitation method \ chemical reagent algae removal method), and biological methods (aeration, microorganisms and animals and plants absorb harmful substances), but the disadvantage of these methods is that the scope of influence is small (such as sludge cleaning in physical methods and clay covering method), it is easy to cause secondary pollution (such as chemical methods, biological methods, etc.), and ev...
