Important Medicinal Plant

Neptunia oleracea is an important medicinal plant used in treating various ailments in different countries. The plant contains chlorophyll-related compounds, amino acids, vitamins, etc. The presence of pheophorbide a and its related compounds make this plant a promising antitumor plant. The plant is used for sewage water treatment and is also utilized in nitrogen fixation in a wetland ecosystem. The present review emphasizes the traditional uses, biological activites and phytochemistry of N. oleracea.

Sewage Water Treatment

Activated sludge method is mainly used to sewage water treatment of water injection system in oil field, dissolved oxygen of sewage pond plays a important role in the sewage water treatment process. The proportional control algorithm of dissolved oxygen concentration is developed based on a first time delay model, and the parameter values of the controller is determined by using stability margins design approach. Simulation results are provided to illustrate the design procedure and the effectiveness of the proposed methods. When applying to the wastewater treatment system based on activated sludge, this method can achieve a satisfied treating performance with robustness. Simulation results are given to demonstrate the design procedure and the effectiveness of the proposed methods.

Sewage Water Treatment

The usage of natural sorbents in sewage water treatment technologies, in particular agro-industrial complex, has a number of environmental and economic advantages. Non-traditional sorbents, which are concentrated in many parts of Ukraine, are cheap raw materials for sewage water treatment. The sorption properties of the upland and lowland peat species of the Gamaliivka-Grybovychi deposit, which were studied early, indicate their high sorption capacity for ammonium ions, which, if they enter water bodies, cause a number of environmental problems. According to the results of the ecological assessment of sewage water of meat processing facility, the chicken processing facility and milk processing plant, it was found out the exceedance of the acceptable limits for the content of ammoniacal nitrogen, respectively: 1.3–3 MPC; 3.8 MPC and 2.5 MPC. This component is a water pollutant and a “crop” of yield in agriculture, since nitrogen is an important element of plant nutrition. The rational usage of natural resources involves the complex usage of natural resources. The nitrogen absorbed by ammonium peat, as well as the peat itself is a sufficient fertilizing land, so the use of used peat complex in agriculture allows to solve not only problems of fertilizers, but also to achieve greening in sewage water treatment technologies. Greening as a whole is a result of waste minimization, and today there are two main areas: new technological non-waste technology together with low-waste technology and waste regeneration. This paper presents a comparison of the physiological indices of plants, depending on the application of the species and form of Gamaliivka-Grybovychi peat deposit, Yavoriv district, when fertilizing the substrate (sand as a background) of the study areas. The influence on the quality of ascent and growth of vegetative culture – watercress, natural form of the top and lowland peat species, as well as their waste forms obtained as a result of the process of purification of ammonium ions, modeling the sewage water of the agro-industrial complex, was investigated. The mass of the harvest from the experimental fields was determined and compared. The differences of lowland and upland peat species are due to its origin, which significantly affects their chemical composition. The plants fuelled with peat are much higher in the mass than those crops that were grown with adding of peat substrate into the lowland. However, the used form of lowland peat provided a 1.57 times higher harvested crop yield than the used upland sample of the studied sorbent.
