Problems solved by technology

Especially in cities, in order to meet the needs of flood discharge, river reconstruction is only considered from an engineering point of view, the river is cut and straightened, and the three sides of the river are solidified with cement and steel. The environment in which organisms live disappears, and their ecological functions and net capacity also degrade accordingly, which directly leads to the disappearance of a large number of organisms in the river channel. High-load pollution discharge easily collapses and disintegrates the internal ecosystem of the river channel water body. Severe siltation also basically loses the flood discharge function.
There is currently no ideal treatment method for this kind of problem. Most of the methods involve dredging treatment, and the investment cost is relatively large, which cannot fundamentally solve practical problems.
[0003] How to restore the original ecological structure of the river and create a good living environment, people have carried out a lot of work. For such problems, most of the methods involve dredging and treatment, the investment cost is relatively large, and they cannot fundamentally solve practical problems. Based on This paper proposes an integrated technology for bioremediation of river water

Embodiment 1

[0063] A treatment system for river water pollution, which includes an integrated microbial activation device installed on the second bank of the river, equipment rooms, pump wells and pipelines for transporting water, of which:

[0064] The pump well is designed in the center of the river 1.5km downstream of the seriously polluted river section, and there are two lift pumps, grids, rams and lifting devices inside. The grid is placed in the pump well, the lift pump is placed in the grid, and the grid lifts To intercept debris in the river to avoid blocking the lift pump; there is a ram connected to the grid, and the lift pump will be lifted away from the pump well after the ram is opened, and the lifting device will lift the lift pump away from the pump well for easy maintenance;

[0065] The equipment room is located next to the pump well on both sides of the river bank, and has a lift pump power supply system and an automatic control system for the lift pump inside;

[0066]...

Embodiment 2

[0068] A treatment method for river water pollution, comprising:

[0069] (1) Digestion of river sediment:

[0070] Sprinkle the microbial composite preparation directly into the river water body, the microbial composite preparation naturally settles into the bottom mud, and performs bioremediation on the bottom mud of the river channel water body; the microbial composite preparation has a limited composition:

[0071] Microbial preparation content micro 1 × 10 6 / mL; dosage: 10g / m 3 sludge

[0072] The dosage of microbial growth promoter is: 0.2g / m 3 sludge

[0073] Auxiliary agent dosage: 5mg / m 3 sludge;

[0074] The microbial bacterial preparation refers to: a powdery bacterial preparation composed of Bacillus, Paracoccus, flocculating bacteria and photosynthetic bacteria; wherein the weight ratio of Bacillus: Paracoccus: flocculating bacteria and photosynthetic bacteria is 5:3:2:1; The microbial growth promoter is BE extracted from "weathered lignite" in the southwest...

Embodiment 3

[0082] A certain river in Tianjin has a total length of 5km, a river width of 20m, and a regular water level of 1m deep. GB3838-2002) in V class water quality standard, restore the self-purification ability and landscape function of the river section. The following measures have been taken to ensure that this type of water body meets the standards. The water quality and compliance indicators of the river course are shown in Table 1 below.

[0083] (1) Digestion of river sediment:

[0084] Since the river channel has already been dredged, there is no need for sediment digestion within three years, and the addition of microbial compound preparations for sediment digestion can be omitted. After three years, the addition of microbial compound preparations can be increased year by year, and then start. Sediment digestion.

[0085] (2) Oxygenation device:

[0086] A submersible pump (on the second bank of the river) is installed 2km away from the upstream of the river, and a subm...

Abstract

The invention provides a treatment method of riverway water body pollution, and a device and application thereof. The method comprises the steps of digestion of riverway bottom mud, an integrated microorganism activating device and riverway water body oxygenation and the like, wherein microorganism compound preparation which needs to be added in the digestion of riverway bottom mud is the mixture preparations prepared from a high-efficiency microbial flora preparation (microbial flora content is 1*106 / ml) (added amount is 10-20g / m<3> sludge), a microorganism stimulant (added amount is 0.2-0.5g / m<3> sludge) and an assistant medicament (added amount is 2-5mg / m<3> sludge). A damaged city riverway system is restored and perfected by a series of means. The creatures in the system coexist, biological diversity is increased, ability to resist external disturbance is enhanced, and the system can be kept in a good state through the restoration of the riverway ecological system. A beautiful living environment is created, a demand of ecological civilization construction is met.

Description

technical field [0001] The invention belongs to the technical field of environmental protection. The invention relates to physical, chemical and biological restoration technologies in the field of river course governance and wetland restoration, and a comprehensive treatment method for river course water bodies integrating multiple treatment technologies. Background technique [0002] With the rapid development of society and economy, the population has grown rapidly, the discharge of pollutants has increased significantly, environmental protection has lagged behind, and the level of governance has not kept up with the high economic development, resulting in a large number of pollutants entering the water body with sewage, garbage, precipitation and runoff, resulting in The quality of the environment has deteriorated. Runoff pollutants are directly discharged into rivers without treatment, causing serious pollution to water bodies. Especially in cities, in order to meet the...
