초록

The purpose of this study was to determine the effect of milking system type on milking center effluent production through the four seasons. Four different types of milking systems(Bucket, Pipeline, Tandem and Herringbone) were estimated, in duplicate, through the different seasons. The following conclusions can be drawn from this study.
1.The quantity of wastewater produced from Tandem and Herringbone milking systems were significantly larger than Bucket milking system(p<0.05).
2.The main wastewater production was from the washing of milking apparatus. Tandem and Herringbone milking systems produced 398.8 and 407.7ℓ/day of wastewater, respectively, for apparatus washing. These values were significantly higher than the other milking systems during the summer(p<0.05).
3.The average wastewater production from the various milking systems was 15.4ℓ/head/day. The quantity of wastewater production during summer(16.4ℓ/head/day) season was higher than of the other seasons.
4.The highest level of BOD5(906.4mg/ℓ) was produced from the washing of the parlor floor and the lowest level of BOD5(212.4mg/ℓ) was produced from the washing of the udders of the cows.
5.The pH of dairy wastewater was in the range of 7.3～8.2 and the average levels of BOD5, COD, SS, T-N, and T-P were 731.2, 479.0, 751.6, 79.1, 14.7mg/ℓ, respectively.
Following conclusions can be drawn from this experiment. The quantities of wastewater production from Bucket, Pipeline, Tandem and Herringbone milking system were 143.9, 487.9, 914.0, and 856.7ℓ, respectively. The average wastewater produced from the milking systems was 15.4ℓ/head per day.
In order to effectively manage on the wastewater from milking systems, dairy farms need to consider the milking system type and farm size when determining the optimum wastewater treatment system.
