Recycling type Livestock Wastewater Treating System

The present invention relates to an energy-saving livestock waste treatment and recycling device linked to an environmentally friendly wastewater treatment device.

More specifically, it is a high-concentration organic waste from livestock farms that treats livestock manure (swine manure) to continuously recover resources (biogas and liquor), and livestock manure (swine) that cannot be put into wastewater or recycling processes generated after resource recovery. Sediment accumulated in the environment-friendly wastewater treatment of manure) can be used as fertilizer (compost) and treated water to be treated as heavy water or industrial water to treat livestock manure to reduce environmental pollution and obtain energy sources. The present invention relates to a hybrid resource system having a hybrid function, and a livestock manure (swine manure) processing device is buried underground, and the generated biogas is a resourceization device connected to the livestock manure processing device of the present invention. , Combined with solar generators, cogeneration Energy).

The livestock industry is an important industry among agriculture that provides high protein food to our people. Our country has grown quantitatively and the number of livestock farmers has increased, and the number of heads has increased greatly. With the problems of wastewater treatment, various diseases, soil pollution and groundwater contamination due to excessive farmland spraying, problems with the treatment of livestock manure have emerged as an urgent problem to be solved.

Particularly, livestock wastewater contains manure in the urine even if the manure is efficiently separated into solid-liquid, which is a pollutant for the environment. It is high in organic matter and contains a lot of nitrogen and phosphorus. In this case, it is regarded as a harmful substance to the environment that has more water pollution effects than domestic sewage. Although it is difficult to treat by general wastewater treatment methods, the cost of constructing and maintaining livestock manure treatment facilities is too high and proper treatment technology is also used. Since it is not established, there is a demand for a method that can economically and effectively treat livestock manure and livestock wastewater from livestock farmers, which has been commercialized due to the fact that a considerable amount is unreasonably dumped at sea due to the fact that a reasonable treatment method has not been established.

In addition, the development of alternative energy is inevitable in the era of high oil prices, so the biogasification of livestock manure is the most active response to eliminate waste, reduce environmental pollution and obtain energy sources.

As a conventional recycling facility, the livestock waste treatment system is difficult to secure enough space for treatment, lack of know-how in digester operation, lack of technical system, frequent machine failure due to insufficient pretreatment of raw materials, lack of utilization of anaerobic digestion solution, utilization rate of production biogas Of course, problems such as low tide,

Waste water exceeding the amount that can be treated in the recycling facility is generated and discharged as it is.In addition, odor is also generated during the process of transportation, which causes secondary pollution. As a secondary treatment device that can be solved, development of an economical and environmentally friendly wastewater treatment device is actively required.

In general, the components of the digestive gas generated during livestock manure treatment differ depending on the properties, but in the crude state, 55-60% of methane gas is usable, 40-45% of inert gas carbon dioxide, and hydrogen sulfide. It is reported that about 2% of other harmful substances such as moisture, nitrogen, and the like are urgently needed to establish a gas purification system to improve its utilization.

In addition, the water to be treated in the wastewater treatment facility is discharged as it is, so it needs to be treated with water quality that meets the water quality standard so that it can be used as heavy water such as cleaning water or toilet washing water.

As described above, the conventional livestock waste treatment apparatus has various problems.

It is a high-concentration organic waste from livestock farms that treats livestock manure (swine manure) and continuously recovers resources (biogas and liquor) and collects livestock manure (swine manure) that cannot be put into wastewater or recycling processes. Sediment accumulated by environmentally friendly treatment of livestock wastewater is a technical alternative for fertilizer (compost) and effluent reuse.Treatment water can be treated as heavy water or industrial water to effectively treat livestock manure to reduce environmental pollution. There is a technical problem to be developed by linking the wastewater treatment system with the economical and environmentally friendly treatment and resource treatment of livestock manure from the barn, which also provides energy sources.

The present invention has been made to solve the above-mentioned problems of the prior art,

Recovery of nitrification activity by maintaining a rapid neutral state, anaerobic fermentation tank (anaerobic digestion process, biological treatment method that generates organic methane, CO ₂ gas or hydrogen as a final product by gradual decomposition of organic substances in waste water by using anaerobic microorganisms) Forming sequentially to generate biogas and liquid fertilizer, but forms a livestock waste treatment and recycling device to supply biogas purified and supplied with high purity using a desulfurization device and a purification device,

The low concentration wastewater generated after methane fermentation and the livestock wastewater separated after the solid-liquid separation are pretreatment devices (sedimentation + filtration) and the main treatment equipment (multi-stage equipment, air and chemicals while the wastewater flows), which commonly use the natural flow method at the rear of the resourceization device. , The purification efficiency is increased by aeration-type chemical injection with agitation), and the wastewater treatment system which is linked with the post-treatment device is re-treated to reprocess the treated water generated in the livestock waste treatment system. Stable treated water quality meets discharged water quality standards and can be used for heavy water.In the waste water treatment process, suspended solids are incinerated at incinerators, but air cleaners are released to release clean air to the atmosphere. Eco-friendly wastewater treatment system that can be reused as compost for proper treatment It is an object of the present invention to provide an energy-saving livestock waste treatment and recycling device.

The energy-saving livestock waste treatment and recycling device linked to the environmentally friendly wastewater treatment device of the present invention,

In particular, the wastewater treatment apparatus applied to the present invention is operated in a multi-step repeatable natural flow method, which greatly reduces the power cost, and mixes with the oxygen supply so that air and chemicals are introduced and stirred while the wastewater flows due to falling. As a system that automates the entire process such as chemical supply, compact and automatic unmanned operation of the device is possible, which reduces the environmental load and reduces the operation and maintenance costs by reducing various reactor capacity.

In addition, the present invention can be installed in the basement compactly in the source of livestock manure to block the source of environmental pollution, and can simultaneously supply useful energy and fertilizer for each application such as electricity, heat by solar and wind generators as well as biogas and liquid Only electricity generated at livestock manure processing sites can satisfy heat demands such as flower vinyl houses and livestock houses, as well as gain surplus power.

Therefore, the present invention collects and recycles unutilized energy that is discarded by powering the entire livestock waste treatment and recycling apparatus and simultaneously solves the environment and energy problems, and simultaneously has the environmental friendliness, energy saving and flexibility of energy supply.
