Comprehensive treatment system of urban river water area ecological environment

Abstract

The invention relates to a comprehensive treatment system of a urban river water area ecological environment, which is an effective ecological environment control measure implemented on the basis of the support of a state environmental protection policy and the financial support. The invention is widely suitable for ecological environment treatment of surrounding rivers of mountainous and plain cities. Under the same treatment scale, the construction investment due to the adoption of the technology of the comprehensive treatment system of the urban river water area ecological environment is much lower than that due to the adoption of the environment control mode of the traditional large-scale sewage treatment plants, garbage power plants, and the like, and the comprehensive treatment system is an ecological circulation control measure which is more effective and economical than all traditional environment control methods and is also an only environment control method by which the control output is much larger than the construction investment at present. The construction investment can also be input stage by stage according to a mode demanding treating water firstly and treating solids later, the treatment scale can be adjusted according to demands, and the invention has strong regional adaptability.

Description

1.0 Technical field [0001] The invention relates to related schemes and technical implementation measures of environmental governance in urban construction and development 2.0 Background Technology [0002] Urban sewage and garbage treatment. [0003] As we all know, the current environmental governance adopts the separate treatment of sewage and solid waste. In economically developed large and medium-sized cities, the fecal sewage in residential quarters is subjected to simple pre-filtering and biochemical treatment in septic tanks or biochemical tanks. Generally, the sewage treated by biochemical tanks can reach the third-grade water quality standard, and then the sewage is treated by the city. The sewage pipe network is transported to the urban sewage treatment plant for centralized treatment and discharged to the river after meeting the secondary water quality standard. Urban solid waste is collected and transported to large waste disposal sites by means of garbage sta...

Problems solved by technology

1. The three methods all need to invest a lot of money to establish a sound Transshipment management system and building facilities; 2. The longer transshipment period causes a certain degree of secondary pollution, Landfilling will cause regional pollution to the landfill area, and incineration and power generation will The atmosphere causes serious clean pollution; The current three treatment methods all have serious interference Net pollution, landfill and incineration methods are not available Product, input and output cost of waste-to-energy The ratio is extremely low, and a large amount of Dioxin gas
