Problems solved by technology

[0006] Urban domestic sewage is a kind of sewage with complex components, including organic matter, inorganic matter, water-soluble, insoluble or water-insoluble compounds, as well as hospital waste water and industrial waste water mixed in it, and the flow rate is unstable and the composition large fluctuations
A considerable number of industrial polluting enterprises in our country would rather be punished than invest in wastewater treatment. Even if there is a sewage treatment plant, the operation is extremely abnormal. The lack of funds is the main reason for the serious lag of sewage treatment in our country.

Embodiment 1

[0035] 1. The ratio of high-efficiency microbial compound agent:

[0036] 12 grams of nitrifying bacteria, 10 grams of denitrifying bacteria, 10 grams of phosphorus accumulating bacteria, 12 grams of bacillus, 8 grams of photosynthetic bacteria, and 15 grams of yeast. Each gram of culture medium for a single species of bacteria contains 200 to 300 million bacteria.

[0037] 2. The method of using high-efficiency microbial compound agent to treat sewage, including operation units such as grille, regulating pre-sedimentation tank, biochemical tank, flocculation sedimentation tank, sludge concentration tank, etc.

[0038] (1) System debugging stage: after the sewage passes through the grid to remove large suspended solids, it enters the regulating pre-sedimentation tank to remove most of the sediment in the sewage, adjusts the pH value of the sewage to 6-9, and the temperature is 5-35°C. Add slow-release hydrogen peroxide 1.0g / m at the inlet of the sewage overflow tank after the ...

Abstract

The invention discloses a microbe complexing agent with high efficiency and method using thereof for processing municipal wastewater. The microbe complexing agent contains 5-20 shares of nitrifying bacteria, 5-20 shares of denitrifying bacteria, 5-15 shares of bacillus brevis, 5-20 shares of photosynthetic bacteria, 1-20 shares of saccharomycete, each grame culture medium of single species bacteria contains 1.0-3.5 hundred million numbers of bacteria. The invention adopts improved bio-contact oxidation process with a microbe complexing agent with high efficiency as main body, adopting soft assembly complexing biology stuff as biology carrier, increaing anoxia step in a integral SBQ biochemistry treating pool to make hydrolysis and good oxygen oxidize as an integer, nitrifying and denitrifying finished in a pool, removing effectively ammonia, nitrogen and phosphor via aeration regulation and regulation of microbe reaction process. The microbe complexing agent is in characterized in high efficiency and no pollution, the waste water processing method with low cost, less invest, low operation cost, and the method has strong adaptability, less mud product, having better economy and social benefit.

Description

1. Technical field: [0001] The invention relates to a sewage treatment technology, in particular to a high-efficiency microbial compounding agent and a method for treating urban sewage by using the compounding agent. 2. Background technology: [0002] As society pays more and more attention to water environment protection, the government has also put forward higher water quality requirements for sewage treatment. In order to degrade BOD 5 The nitrogen and phosphorus that cause the eutrophication of the water body are removed while the pollutants are removed. In recent years, biological nitrogen and phosphorus removal treatment technologies - A / O method and A / A / O method have been widely used at home and abroad. These two processes can be applied not only to the traditional activated sludge process and staged water inflow process, but also to oxidation ditch, SBR process and AB process to further improve the quality of effluent water. However, since the operation process req...
