Description

Smart farm interlocking livestock wastewater treatment facility using a micro bubble generator alternately}

The present invention relates to a smart farm linked livestock wastewater treatment system using alternating microbubble generating unit included in the liquid fertilizer treatment unit for livestock wastewater treatment.

Livestock wastewater is recyclable as compost or liquid manure after a given treatment, but is a source of serious odors and a high concentration of soil and water pollution. Livestock wastewater accounts for only 0.6% of the total wastewater generated, but the pollution load is 25.8%.

In addition, the livestock wastewater generated by one livestock is quite large. Under the Act on Sewage, Manure and Livestock Wastewater, more than 38 heads of cattle shall be subject to the regulation of livestock wastewater. In fact, in order to treat livestock wastewater in accordance with the regulations, land for livestock wastewater treatment facilities is needed in pigs and barns.

Livestock wastewater treatment also takes a lot of time. In general, about one month or more is required for the treatment of liquefaction of livestock wastewater.

1 is a view for explaining a general livestock wastewater treatment method. The livestock wastewater from the barn is transferred to the manure mixing tank and then to the solid-liquid separator. In some cases, only one of the manure mixing tank and the solid-liquid separator may be used. Meanwhile, when the livestock wastewater is transferred from the livestock house to the manure mixing tank and / or the solid-liquid separator, the livestock waste and urine are transported together with the help of a mechanical device such as a screw in consideration of the high viscosity, volume reduction, and transfer speed of the livestock wastewater In this process, large quantities of livestock are crushed and kneaded and transported in a mixed form with urination, which is a well-known form of livestock wastewater.

In the solid-liquid separator in which livestock wastewater is introduced, the livestock wastewater is separated into a solid phase and a liquid phase using gravity sedimentation or cyclone, and the separated solid phase livestock wastewater is transferred to the composting unit for composting. Livestock wastewater separated into solid phases averages about 15%. Stocks are generally included here.

As a separate liquid livestock wastewater, about 85% of the livestock wastewater is treated. Liquid livestock wastewater is a high concentration wastewater with a high load of pollution and is mixed in the form of bark, which requires many steps and processing time. It is usually handled in three stages of aeration tanks, which takes about 30 days. The main treatment and the post-treatment are collected in a liquid fertilizer storage tank and used in farmhouses as liquid fertilizer.

As described above, according to the general livestock wastewater treatment method, since a lot of time is required for the water treatment, odors are generated continuously around the treatment plant, and the livestock wastewater treatment plant is regarded as a hateful plant having a serious effect on the region.

In addition, there was a problem of soil contamination due to the nutrient solution waste discharged from the farms receiving the liquid cost of the treated livestock wastewater.

In particular, the exhaust gas emitted from the barn is a serious odor source and a high concentration of air pollutants, so in order to deal with this, a separate exhaust gas treatment facility must be provided, so that the area occupied by the hate facility is large.

In order to solve such a large number of environmental pollution problems, there was a need to develop a system for treating both livestock wastewater discharged from livestock houses and nutrient solution wastewater discharged from smart farms.
