Shipborne water area purifying system and water area purifying method

Abstract

A shipborne water area purifying system comprises an inflator, a water pump, a dosing device, an air floatation device, an electric flocculation device, a sand filter tank and a controller which are respectively arranged in a cabin, the inflator is communicated with the air floatation device and the electric flocculation device through gas conveying tubes respectively to supply compressed air to the air floatation device and the electric flocculation device, the water pump, the air floatation device, the electric flocculation device and the sand filter tank are sequentially communicated through a water conveying tube, the dosing device is connected with the air floatation device for adding a drug to sewage entering the air floatation device, the controller is electrically connected with the inflator, the dosing device, the air floatation device, the electric flocculation device and the sand filter tank respectively, and sewage sequentially enters the air floatation device, the electric flocculation device and the sand filter tank under the water pump, is purified, and returns to an original water area. When an abrupt water area pollution accident occurs, the shipborne water area purifying system can timely enter the polluted water area to purify sewage in order to emergently process the abrupt water area pollution accident. The invention further provides a water area purifying method.

Description

【Technical field】 [0001] The invention relates to the technical field of water area treatment, in particular to a ship-mounted water area purification system and a water area purification method using the ship-mounted water area purification system. 【Background technique】 [0002] Sudden chemical pollution poses a great threat to rivers, lakes and oceans. Most of these chemical pollutions form a relatively high-concentration pollution zone in the water area after a leak or explosion occurs. The traditional purification method of polluted waters is usually to set up corresponding sewage purification devices in the waters, such as aeration tanks, etc. to purify the waters. Generally, sewage purification devices are installed in waters that are more likely to be polluted, such as sewage water inlets. Sudden chemical pollution is often unpredictable, and the polluted waters may not be equipped with sewage purification devices, so that sudden chemical pollution cannot be treate...

Sudden chemical pollution is often unpredictable, and the polluted waters may not be equipped with sewage purification devices, so that sudden chemical pollution cannot be treated in time

However, it takes a long time from the formation of the pollution zone to its complete dilution. After chemical pollution occurs, the pollution zone often has a great impact on the ecology of rivers, lakes and oceans due to the lack of rapid emergency treatment measures.

For example, on July 16, 2010, two oil pipelines in Dalian exploded. This pipeline accident caused thousands of gallons of crude oil to leak. These leaked crude oil seriously polluted the nearby areas and the Yellow Sea. Due to the lack of purification measures to quickly pollute the waters, the The ecology of the Yellow Sea has been seriously affected
