Reinforced black odorous river microecological reconstruction/balance and water quality improvement method

Abstract

The invention relates to a reinforced black odorous river microecological reconstruction / balance and water quality improvement method. When the method is used for treatment, composite microbes are utilized. The composite microbes contain a composite microbial inoculant A, a composite microbial inoculant B and a composite microbial inoculant C in a weight ratio of (6-25):(5-10):(15-35). The composite microbial inoculant A comprises Rhodopseudomonas spheroides; the composite microbial inoculant B comprises lactic-acid-producing Bacillus; and the composite microbial inoculant C comprises low-temperature organic mineralization bacterium. The Rhodopseudomonas spheroides, lactic-acid-producing Bacillus and low-temperature organic mineralization bacterium can adapt to the growth environment of the river course, and have specific treatment capacity for the river course.

Description

Technical field [0001] The invention relates to a method for treating pollution, in particular to a method for strengthening the reconstruction and balance of the black and smelly river micro-ecological ecology and improving the water quality. Background technique [0002] Due to the rapid development of social economy, intensive human activities and irregular discharge of high-concentration pollutants, urban rivers are seriously polluted in water quality and sediments, water bodies have poor self-purification capacity, insufficient water power, and complete degradation of ecological functions. The black and odor pollution of urban rivers has become a global livelihood and environmental pollution problem, and has become one of the most important constraints on my country's economic and social development. In the context of the implementation of the major national science and technology project "Water Pollution Control Technology and Treatment Project", local governments have adop...

However, this method involves the gradual implementation of a series of macro-policies such as water basin planning, and the effective period is long, so it is difficult to take into account sporadic point and non-point source pollution in rural areas.

[0005] 2. Dredging method: It is a method commonly used at home and abroad to control bottom pollution, but its engineering operation volume is large, the cost is high, subsequent treatment cannot be carried out, and it is easy to cause damage to river embankments and river beds, and it is easy to cause secondary pollution;

[0006] 3. River dredging: Dredging can remove the pollutants in the river sediment in a short period of time, but it is easy to damage the ecological system of the river itself, and cannot decompose exogenous organic pollutants, which provides a place for storing dirt and dirt. conditions, the purpose of purifying water cannot be achieved;

The water quality in the river can be purified in a short period of time by means of dilution and transfer, but the conditions required for this method are quite special, and it is necessary to use a special river water level difference or a water pump lifting method to achieve water exchange. It just transfers the pollutants to other water bodies, cannot remove the pollutants, and treats the symptoms but not the root cause;

[0008] 5. Flocculant method: Although flocculation and coagulation can quickly eliminate suspended solids in water bodies, the effect of removing black and odor is not good, and the coagulation time is not long, easy to rebound, unable to remove organic pollutants, and easily cause secondary pollution. To achieve the purpose of river water purification and environmental protection;

[0009] 6. Stabilized pond method: It has the advantages of simple structure, low infrastructure operation cost, and high removal efficiency, but it has problems such as large area, complicated sewage collection, and serious sediment deposition;

[0010] 7. Planting aquatic plants and biological floating islands: the principle of purification is to use plant roots to absorb nutrients, but this method is only an auxiliary means in the process of pollution control and cannot be used as the main means. Single use cannot fundamentally solve the pollution problem
