Micro-polluted water in-situ remediation system

Abstract

The invention discloses a micro-polluted water in-situ remediation system. The micro-polluted water in-situ remediation system comprises a water tank and a biological filler tank isolated from the water tank. The bottom of the water tank is provided with a biological gravel layer. The bottom of the biological gravel layer is provided with a tank bottom drain pipe for introducing water to the bottom of the biological filler tank. A biological filler as a water purification special-purpose microbial strain growth and propagation carrier having a high specific surface area is arranged in the biological filler tank. An upper part of the biological filler tank is provided with a submersible pump for conveying water back to the water tank. The micro-polluted water in-situ remediation system has the advantages that 1, a biology-ecology combined technology is used for high-efficiency purification of water; 2, low-cost low-energy consumption water remediation is realized so that a cost is reduced and a water treatment land occupation area is reduced; 3, a full-automatic process control technology is adopted so that operator supervision is avoided; 4, an oxygenation device is avoided and fountain self-oxygenation is formed; 5, in the whole process, odor is not produced; and 6, after one feeding process, a water change process is avoided forever.

Description

technical field [0001] The invention relates to a water quality circulation self-purification system. Background technique [0002] Artificial waterscapes such as urban landscape water, fountains, rural ponds, and household pools are widely used, but the water quality is easily polluted. Traditional micro-polluted water treatment technologies include manual water change, mechanical filtration, chemical coagulation treatment, external circulation purification treatment, etc., but all have disadvantages to varying degrees. Manual water change requires manual cleaning of the pool, which is labor-intensive and wastes a lot of fresh water resources. Mechanical filtration treatment is to use natural or synthetic media to filter micro-polluted water bodies to achieve the purpose of removing suspended solids in water and increasing turbidity, but mechanical filtration cannot separate soluble organic and inorganic pollutants in water, especially COD, Ammonia nitrogen, phosphorus, a...
