High efficiency combined restoration technology for urban river water bodies

A combined, river-based technology, applied in water/sewage multi-stage treatment, water/sludge/sewage treatment, energy wastewater treatment, etc., can solve the problem of providing sufficient oxygen, removal rate, and ammonia nitrogen degradation rate for the growth of microorganisms and aquatic animals The total nitrogen degradation rate is not high enough, and the organic matter and pollutants cannot be degraded quickly and comprehensively, so as to ensure the water flow of the river, optimize the landscape, and achieve the best water purification effect

Problems solved by technology

[0007] The publication number is CN102010071A, and the invention publication titled "a combined high-efficiency river water purification process" discloses a method of simultaneously using biological filter beds, biological bacterial agent methods, aquatic plant floating islands, and aquatic animal purification methods to filter and purify water bodies. technology, but it has the following defects in actual use: 1. It does not use solar energy for aeration, and cannot provide sufficient oxygen for the growth of microorganisms and aquatic animals in the water body; 2. It does not use microbial compound preparations, that is, it does not follow the three microorganisms It is compounded with the specific ratio of three enzymes, so it cannot quickly and comprehensively degrade the organic matter and pollutants in the water body, and the purification and treatment effect is not good enough; 3. The method of combining ecological base and filler cannot be used for microorganisms. Provide more sufficient growth and breeding places, and the cost of treatment is higher
At the same time, the process also has potassium permanganate index (COD Mn ) removal rate, ammonia nitrogen degradation rate, and total nitrogen degradation rate are not high enough

Embodiment 1

[0043] A section of a river course is 1200m long, with a water depth of 2-2.5m and an average width of 40m. Before the restoration of the water body, the water body was black and smelly, and the test results of the water quality indicators were as follows: DO was 0.80mg / L, COD Mn 15.07 mg / L, ammonia nitrogen 8.47 mg / L, and total nitrogen 12.14 mg / L. According to the results of water quality testing, the river course is determined to take the following measures to purify the water quality of the river course (for layout see figure 1 ):

[0044] Measure 1: Set 450m at the bottom of channel 1 2 Ecological base. The width of the ecological base is adapted to the width of the river. The ecological base is composed of multiple ecological base units 2 set at intervals of 100m. Each ecological base unit is composed of 3 rows of ecological base units 5. The adjacent two rows of ecological bases The distance between the monomers is 0.5 meters, and the eco-based monomers 5 are arrange...

Embodiment 2

[0052] A section of a certain river course is 1130m long, with a water depth of 2-2.5m and an average width of 60m. Before the restoration of the water body, the water body was black and smelly, and the test results of the water quality indicators were as follows: DO was 1.20mg / L, COD Mn 13.25 mg / L, ammonia nitrogen 9.33 mg / L, and total nitrogen 13.72 mg / L. According to the results of water quality testing, it is determined that the river course has taken the following measures to purify the water quality of the river course:

[0053] Measure 1: Set 412m at the bottom of the river 2 Ecological base. The width of the ecological base is adapted to the width of the river. The ecological base is composed of multiple ecological base units set at intervals of 100m. Each ecological base unit is composed of 3 rows of ecological base units. The adjacent two rows of ecological base units At an interval of 0.5 meters, the eco-based monomers are arranged vertically, and the bottom of ea...

Embodiment 3

[0061] A section of a river course is 1230m long, with a water depth of 2-2.5m and an average width of 44m. The test results of water quality indicators before water restoration are as follows: DO is 3.50mg / L, COD Mn 10.86 mg / L, ammonia nitrogen 6.79mg / L, total nitrogen 8.21mg / L.

[0062] According to the results of water quality testing, it is determined that the river course has taken the following measures to purify the water quality of the river course:

[0063] Measure 1: Set 318m at the bottom of the river 2 Ecological base. The width of the ecological base is adapted to the width of the river. The ecological base is composed of multiple ecological base units set at intervals of 100m. Each ecological base unit is composed of 3 rows of ecological base units. The adjacent two rows of ecological base units At an interval of 0.5 meters, the eco-based monomers are arranged vertically, and the bottom of each eco-based monomer is wound to form a sleeve, and the sleeve is fill...

Abstract

Relating to the field of water environment ecological restoration, the invention provides a high efficiency combined restoration technology for urban and rural river polluted river water bodies. The invention comprehensively utilizes a solar energy micropore aeration technology, an ecological base, a microorganism-enzyme composite reinforcement restoration technology, an ecological floating island, aquatic animal throwing and other methods to reduce nitrogen, phosphorus and other organic matters and pollutants in water bodies, thus purifying river water bodies, optimizing the aquatic ecosystem, and simultaneously achieving a landscape optimizing effect.

Description

technical field [0001] The invention relates to the field of water environment ecological restoration, in particular to an efficient combined restoration technology for urban and rural polluted river water bodies. Background technique [0002] With the rapid development of my country's economy, my country's water environment problems have become increasingly prominent, and urban and rural water environments have encountered unprecedented threats. Existing surveys have shown that more than 90% of the urban and rural water ecology in the Yangtze River Delta region has lost its basic functions, urban and rural rivers have been severely degraded due to pollution and ecosystems, and the water quality of the rivers is basically at V or worse. Most of the rivers are seriously polluted, rich Nutritization, blackening and odor, and pathogenic bacteria exceeding the standard have caused a severe environmental and ecological situation, seriously affecting the ecology, production and li...
