JPS5929095A - Method and device for activating deep water layer of lake, pond, dam or the like - Google Patents

Abstract

PURPOSE:To activate a deep water layer in a lake, pond, dam, etc. without interferring the normal-ordered layer of the water temp. stored therein by floating a water tank of an open top type on the water surface and aerating the water in the deep layer part while circulating artificially the water. CONSTITUTION:A water tank 1 of an open top type is floated on the water surface in a lake, pond, dam or the like and the water is fed backward into the deep water layer through a water feed pipe 2 connected to a submersible pump 3. The water is gushed by a gushing water pipe 4 from the deep layer and is circulated by the level balancing effect in the water tank 1. A tubular stirrer 5 or the like is provided in the water tank and the air is mixed as fine particles with the water gushing out the pipe 4 by the air supplied from an underwater blower 6, whereby the water is aerated. Such water is circulated through the pipe 2 to the part apart from the inlet part for the gushing water. Dissolved oxygen is thus increased in the deep water layer and the activity thereof is improved.

As the temperature rises, the water stored in lakes and dams with depths exceeding 10 rn forms 111 layers from the surface, surface water layer, metamorphic layer, and deep water layer. The water temperature changes according to the atmospheric temperature, and the light reaches well (r), and there is also a lot of oxygen, which causes the communities of organisms to disperse and become active. In this layer, changes in water temperature, heat propagation, movement of nutrients, and mixing of oxygen 'νf1) are harmed, and the water temperature at the lower end of the variable layer is reduced to air temperature 2.
90 at 5°C. The deep water layer follows the F direction of the variable water layer C1. The temperature at the F end of this layer is approximately 40°C, and there is a severe lack of oxygen in the bath, so there is no photosynthesis and anaerobic microbial proboscis occurs. In recent years, the occurrence of these anaerobic microorganisms has become more common in lakes and dams located in relatively low-lying areas where there are many nutrients in the reservoir water.

上昇から来る悪影響を避けることができろ。In the above configuration, even if the submersible pump 3 is driven, the water level in the aquarium l is only half the water level due to the spring water flowing through the spring water pipe 4. Underwater blower 6
The air supplied from the tube swirls around the spring water in the tubular agitator 5 and mixes in the form of fine particles, completing the aeration action. Since the water is artificially circulated by being sent to the deep water layer via the water supply monument 2, dissolved oxygen increases in the deep water layer and the activity level improves. Submersible blower
The heat generated when 6 is driven 4 is absorbed by the water in the water 1P41, but if the degree of heat generated causes a large temperature rise in the water conveyed through the water pipe 2, the submersible blower 6 and By providing a partition wall (not shown) surrounding the air supply pipe 6b and communicating the partitioned portion with the surface water layers A to 13, it is possible to avoid the adverse effects resulting from the increase in t quality.
