Example Embodiment

[0033] Example 1

[0034] This embodiment is as figure 1 with figure 2 The simulated urban river course shown in the reactor, simulation A 2 / O process, the simulated urban river reactor includes reactor 1, which has an effective volume of 75L, and is equipped with water inlet zone 3, reaction zone, and water outlet zone 9. There is a first partition between the water inlet zone 3 and the reaction zone. The water baffle 2 is provided with a second water blocking baffle 8 between the reaction zone and the water outlet zone 3, and each section is connected. In order to simulate the light characteristics of natural rivers, the reactor 1 was treated with opaque light around the reactor 1 and operated at room temperature.

[0035] The reaction zone of the reactor 1 is mainly divided into a biofilm reaction section and a floating island section. The biofilm reaction section is equipped with elastic biological fillers, and the floating island section is planted with floating islands. T...

Example Embodiment

[0043] Example 2

[0044] This example is carried out in a simulated urban river course reactor. Compared with Example 1, the simulated urban river course reactor of this embodiment lacks an anoxic treatment unit 5. Others are the same as in Example 1, which simulates the A / O process. The effective volume of the device is 75L, with water inlet area, reaction area and water outlet area, and each section is connected. In order to simulate the light characteristics of natural rivers, the reactor is opaque and operated at room temperature.

[0045] The reactor reaction zone is mainly divided into a biofilm reaction section and a floating island section. The biofilm reaction section is equipped with elastic biological fillers, and the floating island section is planted with floating islands. The reaction zone is divided into 3 sections, namely sections A, B, and C. Each section is equipped with a separate isolation aeration screen head, which can carry out separate aeration. Among the...

Abstract

The invention discloses an in situ purification system for city channel water body, which comprises an ecology floating island in the city channel, wherein a biological membrane reaction section is arranged in the upstream of the ecology floating island, and is divided into a plurality of anaerobic treatment units and a plurality of aerobic treatment units in the flowing direction of water; each processing unit is filled with a biology filler; the aerobic treatment units are equipped with aerating apparatuses. The in situ purification system provided by the invention is flexible in design, treatment units can be configured, in quantity and sequence for example, according to the contaminant variations and contaminant levels of the actual water condition, wherein the biology contact oxidation unit can simulate the operation of A/O, A2/O, rear-mounted oxygen depletion and aerobic biology denitrogenation, and other technologies, so as to reinforce the application range of the system; the ecology floating island unit and the biology contact oxidation unit are used together to effectively remove nitrogen, phosphor, organic carbon, and other contaminants contained in water, so that the water quality is improved, and the effect of beautifying the channel scenery is achieved.

Description

technical field [0001] The invention relates to the technical field of urban river water quality purification and water environment biological ecological restoration, in particular to an in-situ purification system for urban river water bodies. Background technique [0002] Urban river water bodies, as an important part of the city, have a huge impact on the life and production of urban residents. Most of today's urban river water bodies have been polluted to varying degrees, making the construction of the urban ecological environment more difficult. At the same time, the deteriorating urban water environment and social development, as well as urban residents' demand for biomass improvement, have created great contradictions, which need to be resolved urgently. [0003] Water pollution in urban rivers in my country mainly includes organic carbon and nitrogen, phosphorus and other nutrients, and the sources of pollutants are relatively complex, including natural sources and ...
