“…Diferente dos resultados obtidos por Lima (2011) e Oliveira et al (2015), não houve aumento da CE ao longo do experimento, devido, talvez ao tipo de substrato utilizado (britas) em maior proporção. Arunbabu et al (2015) obtiveram uma redução em torno de 20% desse parâmetro. O aumento ou diminuição da condutividade elétrica demonstra quantidade de íons dissolvidos no meio em questão, sendo assim, a condutividade elétrica é função da quantidade sais contidos no meio.…”

A crise hídrica tem levado a sociedade a mudar seus hábitos de uso dos recursos hídricos e o reúso de água torna-se uma alternativa para essa crise. Os sistemas de alagados construídos são de baixo custo de operação e manutenção e podem viabilizar o reúso d’água, além de contar com uma grande eficácia na remoção de impurezas da água. Objetivou-se com este trabalho avaliar a eficiência de um sistema de alagado construído vertical utilizando como substratos resíduos da construção civil e planta ornamental no tratamento de águas cinza escura provenientes de pias de cozinha, além de direcionar a água tratada para o reúso não potável adequado. A água cinza escura foi coletada na cantina da Universidade Federal de Campina Grande campus Pombal, de maio a junho de 2017, e inserida no sistema. O sistema foi construído em um garrafão plástico de 20 litros, formado por camadas de restos de materiais da construção civil. Foram analisados parâmetros físicos, químicos e microbiológicos da água cinza bruta e da água pós tratamento para verificar a eficiência do sistema. Alguns parâmetros tiveram redução maior que 80% que foi o caso da turbidez e coliformes totais, e acima de 90% sendo este para sólidos sedimentáveis. No reúso, foi verificado que a água tratada poderia ser reutilizada na lavagem de veículos e calçadas, rega de jardins, reúso em forragens e pastagem para gado. Espera-se que este estudo possibilite a utilização de sistemas de alagado construído em larga escala para uma maior disponibilidade hídrica.

Greywater reuse through decentralized and low-cost treatment systems emerges as an opportunity to tackle the existing demand for water. In recent years, constructed wetlands (CW) systems and microbial fuel cells (MFCs) have emerged as attractive technologies for sustainable wastewater treatment. In this study, constructed wetland microbial fuel cells (CW-MFCs) planted with Phragmites australis were tested to evaluate the potential of combining these two systems for synthetic greywater treatment and energy recovery. Open (CW) and closed circuit (CW-MFCs) reactors were operated for 152 days to evaluate the effect of energy recovery on the removal of soluble chemical oxygen demand (sCOD), nutrients and total suspended solids (TSS). Results indicate no significant differences for sCOD and phosphate removal efficiencies. CW-MFCs and CW reactors presented sCOD removal efficiency of 91.7 ± 5.1% and 90 ± 10% and phosphate removal efficiencies of 56.3 ± 4.4% and 61.5 ± 3.5%, respectively. Nitrate removal efficiencies were higher in CW: 99.5 ± 1% versus 86.5 ± 7.1% in CW-MFCs, respectively. Energy generation reached a maximum power density of 33.52 ± 7.87 mW m −3 and 719.57 ± 67.67 mW m −3 at a poised anode potential of −150 mV vs. Ag/AgCl. Thus, our results suggest that the incorporation of MFC systems into constructed wetlands does allow energy recovery while providing effective greywater treatment.

“…The number of nitrifying bacteria and denitrifying bacteria has a great impact on NH 3 eN removal efficiency; nitrification and denitrification are the major ways that wetland systems remove TP and TN, while the microorganismliving environment provided together by aquatic plants and substrates determines the conditions favorable to the growth of microorganisms. However, NH3eN removal efficiency is also affected by other factors, causing the NH3eN removal efficiency of constructed wetland substrate systems to become unstable (Arunbabu et al, 2015).…”

a b s t r a c tConstructed wetland systems have been used for treating a variety of household and industrial wastewater; they are a wastewater treatment technology that has high economic efficiency and environmental effectiveness, especially for sewage treatment in rural areas. Medium filler plays an important role in wetland sewage treatment processes. By carrying out a problem analysis of the ineffective operation and treatment of traditional wetlands, this paper designs different constructed wetland fillers to treat rural household sewage. Using the same plants, this paper chooses four different fillers, namely maifanite, steel slag, bamboo charcoal and limestone as substrates to build constructed wetland systems, and studies rural household sewage treatment in order to examine their effects on the degradation of pollutants. The results show the removal efficiencies obtain good effect. The theoretical maximum adsorption capacities of all these media are ordered as: maifanite > steel slag > bamboo charcoal > limestone. The effluent water quality meets the first class A standard of the "Discharge standard of pollutants for municipal wastewater treatment plant" (GB18918-2002). The selection of medium has an important significance for the operating results of constructed wetland sewage treatment systems.
