Embodiment example 1

[0016] Firstly, sampling and analyzing the sewage of Meishu Village, Jinning County, Kunming City, the sewage water quality is as follows: TN 35.36mg / L, TP 4.067mg / L, CODcr 216.22mg / L, BOD 5 150.39mg / L, SS 108mg / L. Put Lite-on biological compound bacteria preparation at the sewage inlet, add dosage according to 30ppm, use the water flow law of the original pond system, prolong the water flow and make Lite-on biological compound bacteria preparation evenly distributed in the water, install the composite carrier at the appropriate position The bacteria bed can increase the rate of bacteria reproduction and decomposition of nutrients, promote the symbiosis of algae and bacteria, accelerate the purification of water quality, and establish a preliminary water ecosystem in the water body. After staying for 72-100 hours, the water quality of the outlet is: TN 6.14mg / L, TP 0.4-0.6mg / L, CODcr42.38mg / L, BOD 5 9.34mg / L, SS 7mg / L. The degradation rates are 82.28%, 82.32%, 80.40%, 93.79%...

Embodiment example 2

[0018] During the period from October 2003 to December 2005, the Caohai Lake in Dianchi, which has many organic pollution load points, a wide area, and a large amount, was treated with biological ecological water treatment technology. First, the water body is sampled and analyzed, and the water quality is as follows: TN 7.48mg / L, TP 1.18mg / L, CODcr 96.9mg / L, BOD 5 8.49mg / L. According to the actual investigation and test data, LITE-ON's multi-functional strains and filter-feeding fish were scientifically configured and put into polluted water bodies. Add bacteria according to the example of 8ppm, 5ppm, 3ppm, one month is a cycle; after the dissolved oxygen in the water body meets the living conditions of aquatic animals, put filter-feeding fish, according to the standard of 5-15 fish per square meter of water surface (7g / tail). Strengthen the decomposition and transformation of beneficial microorganisms, improve the utilization of nutrient elements, restore the food chain of ...

Abstract

The invention discloses a method for controlling a polluted water body, which comprises the following steps of: throwing specific photosynthetic bacteria (Guangbaopai biological composite bacteria) into the water body by adopting a manual method so as to decompose organic pollutants in the water body by microbes and convert the organic pollutants into the substances such as carbon diode, water, gaseous ammonia nitrogen and the like; and reasonably collocating filter feeding aquatic animals (such as fish, bell, clam and the like) and aquatic plants so as to rebuild a food chain in the polluted water body and finish recycle of the pollutants by energy transfer of the food chain. The method realizes degradation and utilization of the pollutants, recovers the self-cleaning capability of the water body and builds and repairs the ecological system of the water body at the same time. The Guangbaopai biological composite bacteria are safe and reliable and have no secondary pollution, so the method has the advantages of saving of use and investment, moderate running expense and strong operability, and is particularly suitable for control of the open large-sized eutrophicated water body and repair of the aquatic ecological system.

Description

technical field [0001] The invention relates to a method for treating polluted water, in particular to a method for treating polluted water by injecting beneficial microorganisms and rebuilding a food chain in the water. This method is mainly used in the treatment, ecological restoration and long-term maintenance of polluted water bodies such as lakes, rivers, ponds, landscapes, and rural villages. Background technique [0002] At present, the problem of water pollution has become a basic reality that restricts the sustainable development of society and economy. Many countries have developed many mature technologies for water pollution control technology for practice, such as: traditional activated sludge technology, SBR reactor, oxidation ditch, Biological aerated filter, hydrolysis-aerobic biological treatment technology, etc. However, the traditional process has high investment and complicated process. Contents of the invention [0003] The invention discloses a treat...
