Latest issue As already know most livestock breeding in our country use bioga system to handle manure of cattle and poultry. However bioga technology has revealed the downside is the bioga tunnel follows the waste water still more organic substances that cause unpleasant odors affect the environment around the same time if the release would caused eutrophication of aquatic organisms occurring anaerobic decomposition processes in water creates a strong stench degrade water quality approach and affect the health of the people.2. The objective of the research project: 2.1. Overall objectiveOur desire is to prove to the people that know if water after bioga be processed simply will make the school environment in livestock and the environment around much better. 2.2. Specific objectives: achieving the following quality products: -The content of organic matter in the water no longer hovering. -Nito and phosphorus in water reduced 95%. -Special water after passing the hot filter no longer smell nasty type B standards (TCVN 5945-1995) 3. Overview According to learn of our group 100% of households and livestock farms in local sewage treatment after breeding by bioga which discharges directly into the environment. Why is it so? According to the understanding of the us, the majority of them to be processed by bioga is clean and safe to the environment. However the following sewage treatment bioga still the many polluting agents especially the organic substances, nitrogen, phôtpho and the gas smell unpleasant.Currently also had many solutions were given to limit the downside on however the cost of high technology and construction area requires considerable system just match the status of large scale ranches. So that farming households and small and medium sized farms in localities yet to forward weight. So we look forward to building sewage systems after the bioga with inexpensive, easy to do but bring high performance to help improve the breeding environment better.4. Research method 4.1. the object of the study: livestock waste water after treatment bioga4.2. time and place of the research: 15/11/2015-15/12/2015 in his Van Huu family households and sledgehammers, the team 9 Quang Vinh Tung, Son Hamlet, Quang Tin, Thua Thien Hue4.3. the lab design and system:-Sampling of water after bioga treatment and analysis: after sampling and analysis, then we discovered water after bioga tunnel still hovering organic substances, especially the amount of nitrogen and phosphorus in black water should be pretty high, odour-causing gray degrade water quality approach compromising to the health of people.-Water sampling approach of waste water after bioga and analysis: when was peace with water after bioga, the amount of micro-organisms in water sharply increased due to the organic waste water from the source provided to the country's marginalized occurs through the anaerobic decomposition by microorganisms cause makes the stench as potent.-Build the filter system: Using the knowledge learned from chemical program 9 is capable of storing carbon on the surface of the dissolved substances and gases we built the system with the composition mainly of charcoal. The filter system consists of 3 hot:Hot 1: preliminary Filter: from above a layer of golden sand, a layer of charcoal, a small class.Hot 2: Filter clean: top down a layer of fine sand, a layer of charcoal, a layer of golden sand, a fine-grained golden sand layer, a layer of charcoal, a small grain of sand layer, a layer of small hotels.Hot 3: reserve: water Tank after tank 1 and tank 2 cross are reserved in hot 3 from 7-10 days to settle small amounts of natural substances of mud in the water.* The system diagram4.4. sample selection method of presentation: Select random samples in bioga tunnel of the breeding facility.4.5. Presented data collection methods: interviews or filling, observation, discussion group.4.6. The research variables: 4.7. The concept, measure, standard reviews (if available) Industrial wastewater standards (TCVN5945-1995) STT parameters limited unit A B C term is the fastest limited1 g suspended solids/ml 50 100 2002 Phosphorus 0.2 0.5 1 ml/g3 nitrogen g/ml 30 60 604.8. data analysis methods: Liquid penetrant principle from where there is a high concentration to low concentration places.The waste water, after being deposited in the bioga tunnel runs through Butler hot preliminary filter. In hot water are preliminary filter the preliminary filter elements hovering and absorb part of gas odors. Then the water is led directly through the tank filter clean, clean filter tank, at the component and the acrid gas hovering rest is filter and absorb over 95%. Then the water has been filtered in the reserve tank 37-10 on to the small amounts of natural substances, sedimentation the sludge in water then into the environment for new or reuse for watering the plants or clean cages.5. The results of research-The content of organic matter in the water no longer hovering.-Nito and phosphorus in the water falling 95% -Special water after passing the hot filter no longer smell nasty type B standards (TCVN 5945-1995)-Improved surroundings perfectly. Before the filter after filter tank 2 after passing through sedimentation tank 36. conclusion Over the course of the project we found quite successful results achieved in comparison with the idea and desire at the beginning.7.
