“…Based on the nitrate removal theory, in the experiments, the glucose is regarded as carbon source, and the elemental sulfur as an electron donor into the reaction system to promote autotrophic denitrification. The impacts of the supplement to improve the biodegradability of nitrification and changing nitrification approach on denitrification are analyzed [5] [6].…”

Based on the biological purification technology combined with the engineering measures, the enhanced nitrogen purification biological experiment is implemented in Wenyu River in Beijing. The water in the river mainly is the outflow from the sewage treatment plant, in which the ammonium (NH4-N) has been effectively removed for the deeply nitrification, while treatment of the nitrate nitrogen (NO3-N) and total nitrogen (TN) is incomplete due to the denitrification. The water has low C/N value and has poor biodegradability. In this study, aiming at the water feature of low C/N and poor biodegradability, the effective way to strengthen denitrification by some enhanced techniques, such as increasing the microorganisms number and biodegradability (ie, improved nitrogen ratio), changing denitrification rates and so on, has been studied. The experimental results show that under the condition of water flow (Q) as 15 ~ 27L/hr, hydraulic detention time as (HRT) 10 ~ 18h, concentration of nitrate nitrogen (NO3-N) as 12.20 ~ 31.44mg / L, and total nitrogen (TN) as 14.50 ~ 34.71 mg / L, the removal rates of NO3-N and TN are over 30%.

“…Loose material, good air permeability and a large specific surface are conducive to make the oxygen enter the wetlands, which can promote nitrification. Porous material has higher moisture content and more contributes to forming anaerobic environment and promoting denitrification [15]. The soil and material with rich Ca, Fe and Al can effectively absorb P. Under the aerobic conditions, the soil is acid, so the soil and material with rich Fe and Al are better on the removal effect of P. However, under anaerobic or facultative anaerobic conditions, filler matrix with rich Ca can promote the removal of P. Chen et al [16]chose the new filter material as constructed wetlands material, in addition to the coventional sand, pine branches, activated sludge and the other active substances were added, in the same time, mixing with iron slag and limestone and so on.…”

Constructed wetland is a new type of water treatment technology which has been in great price for its characteristic including low cost, simplicity of operator and landscape value. Climatic environment and temperature has a strong influence to the wetlands which restricts the application of constructed wetlands in the northern cold areas. This paper elaborated the technical progress of constructed wetlands, analyzed the problems in the operational process of constructed wetlands located in low-temperate areas in winter, offered some solving measures which could make sure the wetlands running steadily including interior structure optimization and external insulation.

Every single Continent is facing water scarcity and is looking at all viable solutions for minimising overuse of scarce freshwater resources. Many of the water sources that keep ecosystem flourishing and feed a growing population have become stressed due to man-made and natural causes. These natural resources will take time to renew and revive to sustain current situation.Prudently use and wastewater treatment is the only sustainable way to minimise the loss. In order to meet man's enormous requirements, industrial, agricultural, and household activities rise in tandem with population growth. In terms of production, consumption, export, and growth projections, the food industries play a significant role in the economic growth of many countries. After the industrial revolution and rapid urbanization results in consumption of water and also generation of wastewaterwhich is significantly distinct in nature, toxicity, and treatability. Traditional wastewater treatment technologies have been successful in treating effluents for disposal to some extent throughout the years. However, in order to reuse treated wastewater for industrial, agricultural, and home applications, advances in wastewater treatment technologies areurgently required. Membrane technologyhas become a popular solution for recovering water from a variety of wastewater sources. This article investigates the most popular membrane methods for wastewater treatment, as well as its merits and demerits.in this paper, Membrane fouling, cleaning, and modules are also discussed with appropriate recommendations are suggested. Usually, some standard wastewater treatment procedures, such as chemical coagulation, adsorption, and activated sludge, have been used for effluent treatmentowing to its cheap operating and maintenance costs, aerobic waste water treatment as a reductive medium is gaining popularity. Some novel technologies like Membrane Process (MP) have key advantages over the other technologies. They can possibly support sustainable industrial growth by saving energy, minimize environment impact, declining capital cost and enhancing raw material exploitation.
