WATER PURIFICATION SYSTEM OF LAKE AND MARSH

摘要

The present invention relates to a water purifying system for a lake. More specifically, the system generates fine air bubbles in a low pressure dissolving tank with the lake water to generate dissolving water and floats the floating substances in the lake water by using a condensing agent and fine bubbles in a dual-floating tank to separate the floating substances. According to an embodiment of the present invention, the system includes: a hydraulic pump which pumps the raw water from a lake to supply the raw water to the dissolving tank in a dissolving apparatus; a chemical tank which stores and supplies a pH adjusting agent and a floating substance coagulant to the dissolving tank; the dissolving apparatus which injects gas into the dissolving tank with the raw water to generate fine air bubbles at a low temperature and dissolves the raw water to discharge the dissolving water; a floating tank which receives the dissolving water from a dissolving water tank in order to separate sludge and purified water by using the coagulant and fine bubbles to float the floating substances in the dissolving water in order to discharge the water to the sludge storage site and lake; and a dewatering apparatus which dewaters the sludge in the sludge storage site to solidify the sludge.
