In the present study, a horizontal subsurface flow constructed wetland (HSF-CW) with a surface area of 240 m2 and HRT of 2 days, was used in the post treatment of a facultative aerated pond. Application rates of 175 kg BOD5 ha? 1 day? 1 and 408 kg COD ha? 1 day? 1 can be considered admissible for HSF-CW operation following a facultative aerated pond. The system presented values for COD, BOD5 and TSS removal of 88%, 98.8% and 99.3%, respectively. The system supported operation at a solids application rate of 23.3 g TSS m? 2 day? 1 for two years without clogging. The species grown in the CW (Brachiaria ruziziensis) presented a biomass produtivity of between 1.86 and 2.55 kg m? 2 y? 1 , providing CO2 biofixation of between 3.10 and 3.98 kg m? 2 y? 1 . The present study, conducted over two years, indicates that the HSF-CW model employed, and the operational parameters proposed, can be used in post treatment for a pond system that is not operating satisfactorily. |

Conteúdo: |
The objective of this work was to evaluate the concentrations and accumulation of macronutrients in conilon coffee (Coffea canephora) fruit, and their concentrations in leaves, over two years, in irrigated and nonirrigated coffee plants. Three-year-old conilon coffee plants of the cultivar Emcapa 8111 genotype 02 were used. An experimental design was carried out in randomized complete blocks, in a split-plot arrangement, with 14 replicates. The main plot factor was irrigation versus nonirrigation of coffee plants, and the split-plot factor was different fruit and leaf collection times. Collections began 10 days after the beginning of flowering and were performed on average every 28 days, until full fruit ripening. At each sampling date, five plants per treatment were picked out, by collecting one plagiotropic branch by plant, separated into fruit and leaves. Each part was dried, weighed, and subjected to the chemical analysis. Macronutrient accumulations and their accumulation rates were determined. According to the regression analysis of the data, fruit macronutrient accumulation curves fit best to sigmoidal equations. Irrigation affects the macronutrient dynamics in fruit and leaves during the fruiting phase of conilon coffee, and increases the accumulation of nutrients in the plant tissues. The macronutrients found in greater quantities are N, K, and Ca, in fruit and leaves, regardless of the irrigation treatment. |
