Research On The Application Of Efficient Biological Agents In The Treatment Of Urban Black And Odorous Water

In recent years,due to the rapid development of China's urban economy and the development of industry and agriculture,the phenomenon of urban black and black water is becoming more and more serious.And the scope of water pollution is very extensive,sewage untreated directly into the river phenomenon is widespread.So the river's black and smelly pollution led to the destruction of the river ecosystem;seriously affect people's lives,shipping and industrial and agricultural production;intensify the water crisis;even endanger the health of the surrounding residents.Therefore,to increase the city black smelly water remediation efforts,not only related to the improvement of urban ecological environment,but also related to the sustainable development of economic society.With the improvement of environmental requirements and the continuous development of environmental biotechnology,bioremediation is a low investment,high efficiency,easy operation and flexible water pollution control technology developed and applied in the production,and in the world is gradually Get wide attention and application.The bioremediation repair technology is mainly through the addition of biological agents to the polluted water,regulating the composition and quantity of microbes in the water body,optimizing the community structure,improving the efficiency of the pollutants in the water with the self-purification ability,so that the river water to the greatest degree of recovery The original self-purification capacity,so that the degradation of pollutants in situ or into harmless substances.Firstly,through the laboratory static test experimental study on self purification capacity of water and impact on water after adding medicament,unable to meet in the water purification water purification based on the research of adding biological agents to strengthen water and improve water quality.It is proved by experiments that the initial water quality in static water will fluctuate slightly,and it will return to normal within a week,and enhance its self purification ability,which can rapidly degrade pollutants within a certain range.The simulated river experiment shows that biologics can effectively improve microbial activity and provide adequate nutrition,so that all kinds of pollutants in water can be rapidly degraded to meet the requirements of water quality,and the content of organic matter in sediment also decreased significantly.In order to verify the efficiency and economy of the agent,also chose the other two kinds of chemicals were tested,in the face of a different degree of pollution of water,different agents have different performance,but overall,regardless of the economy or efficiency,the agent has advantages.
