EVALUATION OF TREATMENT AND EFFECT SYSTEM DAIRY WASTE GENERATED IN PHYSICAL AND CHEMICAL ATIBUTOS AN ULTISOL The effluents generated in dairy industries have high levels of organic matter, fats, nutrients and suspended solids, having to be treated properly. The improper disposal of these waters causes damage to the soil and salinity, sodicity, change in pH, among others. The milk was subjected to a tributary / secondary preliminary treatment consists of railing and grease trap followed by mixing aerated pond, and the effluent generated after treatment applied to the soil furrow irrigation This study aimed to evaluate the efficiency of dairy effluent treatment and reuse its effect in the physical-chemical properties of an argisoil red furrow irrigated. Analyzed for physico-chemical, determining TS, SD,SS, pH, Na+, K+, Cl-, CE, hardness, Ca+2, Mg+2, nitriti, nitrate, COD and BOD for the samples of effluent. Was evaluated the characteristics of N, P, K, Ca+2, Mg+2,Na+, E Cand pH from five depths of. It found removal efficiency of 72.14% for BOD and 56.52% for COD. There was an increase in the concentration of Na+, P, Clin the treated effluent, this fact possibly caused due to accumulation of logo in aerated lagoon. The highest concentration of (Na+) in the soil occurred at the 0-10 cm depth, with a value of 1373.6 cmolcdm-3, decreasing sequentially in the following layers. The higher concentration of magnesium (Mg+2) was 4.00 cmolcdm-3 in the layer of 40-50 cm depth, this occurred because of their high mobility in soil.
