Description

[0001] The present invention relates to an integrated discharge water filter

More particularly, the present invention relates to an integrated effluent filtration apparatus, and more particularly, to an integrated type effluent filtration apparatus which is formed as an integral type drum so as to be efficiently used in a small scale or a village sewage treatment plant, and the discharge water of factory wastewater, livestock wastewater, The filtration materials such as different gravel layers, sand layers, and activated carbon layers are continuously passed through to improve the filtration function capable of effectively removing turbidity substances and suspended substances and to improve the quality of the discharged water, And to a convenient integrated type effluent filtration apparatus.

In Korea, it is difficult to secure stable water resources due to a large change in rainfall depending on regions and seasons. In addition, as urbanization and industrialization rapidly progressed, increase of water consumption, decrease of green area, increase of impervious area such as concrete and asphalt, and groundwater decrease are increasing.

In order to prevent water pollution and to secure stable and economical water resources, it is necessary to economically reprocess sewage with low pollution to clean, landscaping, The water purification system that cleans and recycles water from the toilet has become the biggest concern. It is important that the water quality of the middle waterway is as clean as possible, but it is important to make water quality suitable for the application considering the treatment cost. The water quality goal is to protect the user's health, to ensure comfortable use and stability. To do this, the following basic matters should be reviewed and there should be no hygiene problems.

It must also be free of disruption to use, not to offend, and not to adversely affect facilities or equipment. And the stability of the treatment technology must be established and there should be appropriate indicators for ensuring and determining the level of maintenance.

The water pollution loads of rural rivers in Korea have been increased due to the increase of income, the increase of livestock facilities, the location of amusement facilities, and the development of agriculture and forestry districts. As a result, water quality in the drainage and small river in rural areas is deteriorating, which is causing difficulties in securing high quality water resources as well as agricultural water.

In order to solve these problems, we are also trying to contribute to the healthy development of rural villages and the improvement of public hygiene by installing water discharge facilities in villages to preserve the quality of public water and to create a pleasant living environment.

Most of the small-scale treatment facilities in rural areas in Korea are located in upstream areas of rivers, so it is important to treat them more efficiently. The area where small scale treatment facility is located is mostly rural village unit, and it is known that seasonal change is severe compared with urban water treatment facility as well as the change of occurrence load is large in one day.

In a place where there is a great deal of change in the water quality and the driving personnel do not reside like a small-scale processing facility, a method of operation that is linked to the change of the inflow load and is easy to maintain is needed. Especially, in terms of conservation of water resources in sewage treatment plants, it is required to remove not only organic matter but also nutrients such as nitrogen and phosphorus.

In order to prevent the water pollution in the rural areas in the early stage, small-scale public water treatment facilities installed in villages have increased by more than 50% since 2001. As of the end of 2005, there are about 1,200 facilities However, the operation and management technology due to the increase in facilities is not supported and there is a problem in the normal operation of the treatment facilities in various places.

At present, the method applied to small public water treatment facilities in Korea can be classified into five types according to processing principle. There is an adhesion biological method in which a biofilm formed on a surface of a filter material is oxidized and decomposed by attaching a microorganism to a filter material and agitating the filter material to oxidize and decompose the organic material and there is a floating biological method of oxidizing and decomposing organic matter by supplying oxygen while maintaining the activated sludge in an aeration tank.

In addition, the SBR method that treats organic matter and nitrogen phosphorus through the repetitive operation and the treatment operation (inflow, reaction, precipitation, discharge) by the activated sludge is performed in one reaction tank and the soil treated with aerobic state using the soil microorganism Treatment method, and a capillary infiltration trench method in which soil microorganisms within 1 m from the surface of the soil can survive and the effluent is infiltrated in an unsaturated state to purify the soil.

However, some of these methods have been used in the attachment biology method (contact oxidation method, etc.) using various types of carriers, and the capillary infiltration trench method has been adopted almost at present in newly installed facilities due to difficulties in operation and maintenance, clogging of soil pores, . The adhered biological method has a disadvantage in that the generation sludge is small and the quality of the effluent water is stable, but the treatment efficiency is deteriorated at the time of long operation. In addition, the SBR method has a problem in that there is a small risk of failure due to the mechanical treatment of the sludge, while the sludge has a small bulkiness.
