Ecological environment detection and environmental protection technology becomes an important means to ensure the sustainable development of human beings. Under the premise of the common development of the world’s environmental protection, environmental protection is becoming more and more important. Under the background of the development of science and technology, human beings should also fundamentally solve the ecological environmental protection problem. At the same time, multi-domain ecological environment monitoring data will be used to improve the data processing technology capacity to meet the government’s multi-source control needs and improve the government’s scientific decision-making effect. Starting from the significance of applying ecological environment detection and environmental protection technology, this paper explores and defines the problems existing in the ecological environment detection and environmental protection technology, and puts forward corresponding optimization strategies in combination with big data technology for reference.

Anaerobic digestion of sewage sludge produces large amounts of CO2 which contribute to global CO2 emissions. Capture and conversion of CO2 into valuable products is a novel way to reduce CO2 emissions and valorize it. Membrane contactors can be used for CO2 capture in liquid media, while bioelectrochemical systems (BES) can valorize dissolved CO2 converting it to CH4, through electromethanogenesis (EMG). At the same time, EMG process, which requires electricity to drive the conversion, can be utilized to store electrical energy (eventually coming from renewables surplus) as methane. The study aims integrating the two technologies at a laboratory scale, using for the first time real wastewater as CO2 capture medium. Five replicate EMG-BES cells were built and operated individually at 0.7 V. They were fed with both synthetic and real wastewater, saturated with CO2 by membrane contactors. In a subsequent experimental step, four EMG-BES cells were electrical stacked in series while one was kept as reference. CH4 production reached 4.6 L CH4 m−2 d−1, in line with available literature data, at a specific energy consumption of 16–18 kWh m−3 CH4 (65% energy efficiency). Organic matter was removed from wastewater at approximately 80% efficiency. CO2 conversion efficiency was limited (0.3–3.7%), depending on the amount of CO2 injected in wastewater. Even though achieved performances are not yet competitive with other mature methanation technologies, key knowledge was gained on the integrated operation of membrane contactors and EMG-BES cells, setting the base for upscaling and future implementation of the technology.
