Instructors: PHAM THI KIM CHI 1. Problem As already know most of the livestock industry in our country are using the system to process biogas feces of cattle and natural cam.Tuy biogas technology has exposed the downside is that after tunnel wastewater biogas remains many organic compounds causing unpleasant odors affecting the surrounding environment and if it is discharged into the environment would cause eutrophication of aquatic chemistry occurring anaerobic decomposition process in the country make up odors strong rotten degrade water quality reach and affect people's health. 2. The research objectives of the project: 2.1. The overall objective we desire to prove to the people if the country after biogas is processed in a simple way, it will make the school environment in livestock and the environment much better. 2.2. Specific objectives: product quality achieved the following: - content of organic matter suspended in the water no longer. - nitrogen and phosphorus levels in water dropped 95%. - Especially after the last water purifier tanks odors are standard type B (TCVN 5945-1995) 3. Overview According to the understanding of the group we were 100% of households and farms in local livestock wastewater treatment after treatment with biogas which discharged directly into the environment .In Why so? according to our understanding, the majority of their children that is treated with biogas fertilizer is clean and safe environment then. However wastewater treatment biogas is still the more polluting agents especially the organic matter, nitrogen, phosphorus and gases have odors. Now also has many solutions made to limit processing blemishes but high cost and demanding technology building area is quite large system is suitable only for those farms large scale. So that farming households and small and medium-sized farms in the provinces have yet to reach. So we look forward to building sewage treatment system after biogas cheaply, easy to do but bring high efficiency to help improve the environment on a better breeding. 4. Research Methodology 4.1. Study subjects: water after handling animal waste biogas 4.2. Time and place of study: 15/11 / 2015-15 / 12/2015 at household Vo Van Huu, the 9 villages Son Tung Quang Vinh commune, Quang Dien district, Thua Thien Hue province 4.3. Experimental design and systems: - Sampling and water after handling biogas analysis: After sampling and analyzing the water we discovered after the last pit is still hovering biogas and organic chemicals, specialty nitrogen and phosphorus is in the relatively high black water, gray unpleasant odors degrade water quality approach, which affect people's health. - Sampling reach sewage water after biogas and analyze: the biogas is mixed with water after the amount of microorganisms in water boosted by organic sources from waste water supply occur simultaneously through anaerobic decomposition by microorganisms cause makes stink The stronger rot. - Developing filtering system: With knowledge gained from the carbon chemistry 9 is capable of storing surface solvents and gases should we build systems with components mainly charcoal. The filter system consists of three pools: Pool 1: Preliminary Filter: from above a layer of golden sand large particles, a layer of charcoal, a small hotel class. Swimming 2: Filter Cleaning: from above a layer of fine sand, a layer wood charcoal, a large grain yellow sand layer, a layer of fine-grained golden sand, a layer of charcoal, a white sand granule layer, a layer of small hotels. Swimming 3: Swimming reserve: water through the tank after 1 and pool 2 is stored in tank 3 from 7- 10 days to deposit small amounts of natural mud in water. * Diagram System 4.4. Presentation of sampling: Random sampling in biogas pit of livestock units. 4.5. Present methods of data collection: interview or self-completed, observations, group discussions. 4.6. Variables studied: 4.7. Concepts, measurement, evaluation criteria (if any) of industrial wastewater standards (TCVN5945-1995) No. Parameter Unit Limit A Limit B hour limit C 1 Suspended solids g / ml 50 100 200 2 Phosphorus g / ml 0.2 0.5 1 3 Nitrogen g / ml 30 60 60 4.8. The method of data analysis: As a rule, liquid penetrant from places of high concentration to low concentration where. Water discharge is deposited in tunnel runs directly past biogas preliminary filter. At the preliminary filter tank water is filtered preliminary components and absorb suspended 1 part smelly gases. Then water is led directly through the filter clean, in clean filter, the components suspended and the remaining gases are filtered and absorbed over 95% .Then filtered water reserves in an 37- 10 day of natural settling small amounts of sludge in the water before they are put into the environment or reused for watering plants or cleaning cages. 5. Findings - concentrations of organic matter suspended in the water no longer. - nitrogen and phosphorus levels in water dropped 95% - Special water through the filter when no odors standard type B (TCVN 5945-1995) - Ambient improved completely. Before filtration After passing through the filter tank clarifier 2 After 3 6.Compact comment Through the project we see results quite successful considering the idea and wanted at first. 7.
