specific Embodiment approach 1

[0012] Specific embodiment one: the unpowered urban inland river pollution control system of the present embodiment, it comprises anaerobic biofilter type urban inland river embankment treatment system 1 and aerobic ecological river course treatment system 2 two parts, described anaerobic biofilter type The urban inland river embankment treatment system 1 is built along the river. The aerobic ecological river course treatment system 2 is composed of an aerobic ecological pebble riverbed 2-1 and a flap gate system 2-2. The aerobic ecological pebble riverbed 2-1 is set in At the bottom of the river, the flap gate system 2-2 is arranged downstream of the river and intercepts the river along the width direction of the river. The flap gate system 2-2 intercepts the river water, which can ensure the residence time of the river water in the inland river, and realize the functions of high-level oxygenation and aeration, and water pressure drop.

specific Embodiment approach 2

[0014] Specific embodiment 2: This embodiment is a further limitation to Embodiment 1. The anaerobic biofilter type urban inland river embankment treatment system 1 is mainly composed of the upstream surface 1-1, the backwater surface 1-2, and the source drainage inlet 1- 3. Anaerobic biological filter dam body 1-4, first retaining wall 1-5-1, second retaining wall 1-5-2, first retaining wall outlet 1-6, water storage chamber 1- 7 and the river channel outlet 1-8; the source drainage inlet 1-3 is arranged on the top of the backwater surface 1-2, and the first water retaining wall outlet 1-6 is arranged on the first water retaining wall 1-5- 1, the wall surface of the first water retaining wall 1-5-1 is set opposite to the wall surface of the second water retaining wall 1-5-2, and the first water retaining wall 1-5-1 and the second water retaining wall A water storage chamber 1-7 is formed between the walls 1-5-2, and the water-facing surface 1-1 seals the tops of the first wat...

specific Embodiment approach 3

[0016] Specific embodiment three: this embodiment is a further limitation of embodiment one or two, the anaerobic biological filter dam body 1-4 is formed by piled rubble and then bound and fixed by steel bars, there are gaps between the rubble , and there is a self-formed anaerobic biofilm on the surface of the rubble.

[0017] The anaerobic biofilm contains a large number of anaerobic bacteria, which can effectively degrade refractory organic pollutants in water bodies.

Abstract

The invention discloses an unpowered urban inland river pollution control system and an unpowered urban inland river pollution control method and relates to an urban inland river pollution control system and an urban inland river pollution control method. The unpowered urban inland river pollution control system and the unpowered urban inland river pollution control method can reduce the operation cost in an inland river control process. The unpowered urban inland river pollution control system consists of an anaerobic biological filter urban inland river dam treatment system and an aerobic ecological riverway treatment system, wherein the anaerobic biological filter urban inland river dam treatment system is built along a river; and the aerobic ecological riverway treatment system consists an aerobic ecological pebble river bed arranged at the bottom of the riverway and a drop flap gate system arranged on the downstream of the river and stopping river flow along the width direction of the river. The unpowered urban inland river pollution control method is as follows: sewage is treated in the dam anaerobic biological filter and controlled by an inland drop aerating aerobic ecological riverway alternately to be purified, and the appearance of the water is improved and the water is purified by the anaerobic and aerobic ecological treatment. The system and the method can be used in the field of urban inland river pollution control.

Description

technical field [0001] The invention relates to a system and method for controlling urban inland river pollution. Background technique [0002] In the initial stage of construction, each city has one or several urban rivers, whose main functions are flood discharge in rainy season and urban sewage discharge river. However, with the improvement of the degree of urbanization and the improvement of people's requirements for environmental quality, the water body function of urban inland rivers has changed from sewage discharge rivers to landscape and flood discharge rivers. However, due to the poor water quality of the first rain in the city, the rainwater after ground runoff is close to or exceeds the water quality pollution level of the urban sewage plant. Moreover, residents along the river dump domestic garbage into Hanoi, and businesses secretly discharge waste water into the inland river. Therefore, urban inland rivers are seriously polluted. The governments of various ...
