The promotion of biogas production in farm animals,
history
.The service unit of biogas. Institute of science and Technology University plans to work to promote. And released biogas production In farm animals, medium, and large.National Energy Policy Office (nepo)Since October 2009. 2538 with the goal of system construction of biogas. The total volume 50 000 cubic meters, within a period of 6 years (the project. Phase 1 and phase 2) by first year target system construction, the 3000 cubic meters. Two years 7 000 cubic meters, and then another year, 10 000 cubic meters until the period project 6 years
.At present, the unit of biogas. Is to focus on services for biogas production in the farm to planning system of biogas and components to suit the condition of the area within the farm.Alongside the biogas production To use renewable energy within the farm and at the same time, the system will help to deal with the waste. Occurring within the farm system. And produces the maximum benefit.And started walking system, each farm to take action. And manage it as soon as possible. To cause the ability. To take care of the system with the personnel of the farm itself sustainably.Based on the general principles of management environment. In the form of commercial. In order to comply with the system of business!
Biogas technology is a technology that was based on the principle of degrading organic matter. Biological anaerobic (Anaerobic Digestion) by the creation of conditions for the bacteria contained in nature. ย่อยสลาย organic matter.As a result of the fermentability was a mixture of the flammable gas, which is methane (Methane) is a core component of approximately 70% biogas has. Can be used in cooking or kg pigs, as well as applied to boiler hot water.As well, focusing on the use of Biogas The most direct heat production. In order to increase the thermal efficiency of the system uses and if there is plenty of more than enough.To produce electricity

biogas system in animal farm. A system with multiple components Working together as well. Which can be divided into stages of system is the main. 3 steps
.1) step 1 is decomposed organic matter. In the pond fermented rails (Channel Digester) in this process, the fermentation pond แบบราง also serves to separate the waste and thick. And the clear off from waste and concentrate, will be fermented in the pond bioreactor sub table atThe day that is in a state of stable (stabilized) and enters into the filter solid (Slow Sand Bed Filter:SSBF) by the filter, is connected to the pond fermented rails. And waste the concentrate through the fermentability. From fermented waste pond table obtained from the filter solid. Can be used as organic fertilizer.As well as used in planting grass in the business golf course. For the clear waste which were 80 - 90% of total waste will flow through to the pond fermented UASB (Upflow Anaerobic Sludge Blanket. Reactor) for therapy in step 2 next
.2) step 2 therapy and biodegradable happened in the pond fermented UASB (Upflow Anaerobic Sludge Blanket Reactor) organic mainly in wastewater. Which is in the shape of a solution is decomposed in the pond, and eventually become UASB biogas fermentationThe wells fermented rails per volume of the pond fermented UASB is about 2-3 per 1 depending on the style properties. Of wastewater from farm system therapy. The water treated by the pond fermented UASB then this is COD, about 800-1000 mg / L, which in the process of therapy without oxygen. Can reduce the contamination of organic matter. Contamination in the wastewater 95 percent of the dirt start
.3) step by step 3 said that the steps of the step after treatment (Post Treatment), which เป็นการบำบัด designed the system to be working at the imitation of nature. By using the function of aquatic plants, algae, and small, and bacteria.Work related to water treatment. The effluent without oxygen. It initially clean even more. To the point that can circulate. Reuse clean the stall and / or released to the outside at the end.Includes outdoor stay open. The wastewater treatment process 2 and released into the lake aquatic plants which grow set some plants for help in wastewater treatment by both direct and indirect.In the last part of the series and marsh plants. A fish pool. For the observation of water quality on living organisms. Water is treated and this will be the last COD expected no more than 200-400 mg / L, and the BOD.60 mg / L, respectively. The standard that PCD acceptable
.
Coagulant for these three steps. Can be recycled within the farm animals, such as is used for cleaning the stables. And / or can be discharged into natural water.
