The present invention relates to a block type water purification device capable of purifying a large amount of leachate, sewage, and the like, and more particularly, the device is easy to move, and a plurality of bidirectional flow paths and filter assemblies are combined to increase water treatment capacity. A block type water purification device capable of treating a large amount of sewage in time and easily replacing the filter assembly.

As the demand for water increases rapidly due to rapid economic development and population growth, various methods for stable water supply have been recently considered.

As one of several measures, large-scale river development and groundwater development are being reviewed and promoted. Recently, river development causes water shortages due to the river's dryness every year, and groundwater contamination and depletion are caused by the development of groundwater. It is becoming increasingly difficult to secure stable water sources.

In particular, in coastal areas, due to unreasonable groundwater development, seawater penetrates into underground aquifers, which further contaminates groundwater itself, making it impossible to use groundwater.

Therefore, in order to prevent water shortage and groundwater contamination, methods of using wastewater such as leachate or sewage are being considered. Leachate or sewage is optimal to be used as an alternative source of water since a certain amount continuously occurs even during a drought or natural disaster.

In order to reuse it, a technology that can completely remove various contaminants contained in sewage or leachate is required.

The amount of domestic sewage, such as sewage, generated from all over the country is about 16,000 thousand tons per day, and is treated through a number of sewage treatment plants and sewage treatment facilities. However, conventionally, by using only simple filtration facilities such as sand filtration or activated carbon filtration facilities to treat the discharged water discharged from sewage treatment plants and sewage treatment facilities, the treated water filtered in the filtration facilities is low grade such as toilet water, sprinkling water, and landscape water. It could only be used as a general purpose water.

Other methods are biological treatment (anaerobic, aerobic, rotating discs, etc.) and chemical treatment (neutralization, flocculation, precipitation, fenton oxidation, etc.) and then discharged to nearby shores or rivers. It is affecting ecosystems such as river pollution and even sea pollution.

Therefore, to solve this problem, sewage or leachate has recently been treated using membrane separation technology. Membrane separation technology has been developed and developed around the reverse osmosis method for desalination of industrial water. Currently used technologies include microfiltration (MF), ultrafiltration (UF) and nanofiltration (NF). ), Reverse osmosis (RO), gas separation (GS) and electrodialysis (ED).

In order to treat a large amount of sewage or leachate, many filter devices using a backwashing method are used.

In this case, since the air inlet pipe 214b of the bidirectional flow pipe located at the top of the hollow fiber membrane module is located at the top of the membrane module, it is used as a passage through which water for cleaning the membrane module is supplied, rather than being used as an air supply pipe. It is not used.
