Reinforced black odorous river microecological reconstruction/balance and water quality improvement method
A technology for black and odorous rivers and water quality improvement, applied in the field of pollution control, can solve problems such as inability to achieve river water purification and environmental protection, inability to remove pollutants, and cure the symptoms rather than the root causes, and achieve rich biodiversity, self-purification ability and ecological The effect of adjustment function improvement

Embodiment 1
[0054] Example 1: Ecological management and ecological restoration of a moat in an old city
[0055] The river is about 2,600 meters long, with an average width of about 15 meters, and a water depth of 1.5 to 3.0 meters. The bottom silt thickness is 0.9 to 1.5 meters. Due to the long-term direct discharge of a large amount of domestic sewage and a small amount of industrial sewage in the surrounding area, the corresponding Over time, the river gushing water body becomes black and smelly, with a transparency of 5 cm, which is a severely polluted water body.
[0056] The entire treatment cycle of this river course is 14 months, and the specific preparation method is as follows:
[0057] (1) Formulating the composite microorganism; the matching weight ratio between the composite microbial inocula is: composite microbial inoculum A: composite microbial inoculum B: composite microbial inoculum C=12kg:6.5kg:20kg.
[0058] The weight ratio of the various strains of the compound microbial age...
Embodiment 2
[0091] Example 2: Ecological management and ecological restoration of a river
[0092] The creek is about 4,200 meters long, with an average width of about 12 meters, and the water depth is 1.5-2.0 meters. The thickness of the black and smelly silt at the bottom of the creek is 1.0 to 1.5 meters. Due to the direct discharge of sewage from residential areas, shops, restaurants, etc. along the river, the flood becomes a sewage channel integrating sewage, flood control and drainage functions, causing the water body to be odorous, with almost zero transparency, and a lot of scum and animal oil floating on the surface With garbage, the color of the water body is shiny and black, the ecological function and balance have been completely destroyed, and the rivers have lost their ability to purify themselves.
[0093] The entire treatment cycle of this river course is 14 months, and the specific treatment process is as follows:
[0094] (1) Preparation of composite microorganisms; composite ...
Embodiment 3
[0121] Example 3: Ecological management and ecological restoration of rivers in a city
[0122] This creek has a total length of 2.4km, the maximum width of the river is 30m, the minimum width is 10m, and the average water depth is 2.8m. The underground river branch connected to the creek is about 4km long. According to on-site survey statistics, the bank includes domestic sewage, restaurant sewage, animal breeding wastewater, industrial wastewater and septic tank direct sewage, etc. Every day, about 15,000 tons of sewage passes through the sewage outlet and dozens of small undercurrents and small branches. Influx into the main river (calculated according to the daily drainage (sunny) scale of the sluice gate), and the amount of sewage discharged in rainy days is more than 150,000 to 200,000 tons (calculated according to the river bank scale data), and all sewage is collected after the main gush , Discharged into the Pearl River through the sluice. Due to year-round accumulation...
