Specific microorganism activating filler for treating black and odorous water bodies

Abstract

The invention provides a specific microorganism activating filler for treating black and odorous water bodies and belongs to the technical field of water treatment. The filler is prepared from the following raw materials in parts by weight: 3-5 parts of a microorganism inducer, 40-80 parts of an attachment carrier, 0-10 parts of an organic macromolecule polymer, 0-4 parts of an inorganic flocculate and 1-30 parts of an oxidization decoloring agent, wherein the microorganism inducer comprises nitrobacteria and / or denitrifying bacteria and a culture medium matter for the growth of the nitrobacteria and / or the denitrifying bacteria. The filler provided by the invention has the advantages that traditional water body purification is broken through; indigenous microorganisms of the water bodies are activated mainly and the water bodies per se serve as cultivating and breeding bases, so that the growth space of the microorganisms is greatly released, the effective biomass and the functionality of the microorganisms are increased, the microbial ecosystem of the water bodies is recombined, improved and optimized and the self-purification capacity of the water bodies is realized eventually.

Description

Technical field [0001] The invention belongs to the technical field of water treatment, and is used for a specific microbial activated filling material for treating water bodies. Background technique [0002] With the development of cities, environmental pollution continues to plague the lives of residents, air pollution, surface water pollution, soil pollution and so on. The development of mankind depends on water, but the water on which we live has changed, becoming black and smelly. [0003] Black and smelly water is an important manifestation of current water pollution, that is, a large amount of nutrient elements such as nitrogen and phosphorus are accumulated in the water body, the water body is severely hypoxic, the sediment historical sedimentation is serious, the water body transparency is poor, and the essential problem is the destruction of water body biodiversity. This causes the system to lose its self-sustaining and self-regulating ability, and the system balance bec...

AI Technical Summary

Problems solved by technology

Sediment dredging technology often involves a huge amount of work, and it is easy to cause secondary pollution problems; it is a common method to control water pollution by diverting and changing water and diluting the impurity concentration in water, but for isolated remote closed water bodies, It is often difficult to clear and release turbidity; aeration and oxygenation can increase the dissolved oxygen in the water body and improve the black and odorous water body, but it is difficult to fundamentally remove the pollutants, often treating the symptoms but not the root cause. Self-purification ability has not been effectively restored

[0006] Chemical methods: such as adding chemical agents to kill algae, adding iron salts to promote phosphorus precipitation, adding lime to denitrify, etc., but it is easy to cause secondary pollution, and the operating cost is extremely high, usually only as an emergency measure to deal with sudden water pollution

[0007] The traditional biological bypass water treatment process can effectively remove organic C, N, and P in wastewater, but its biological removal mechanism is completed in a closed microbial action unit, and phosphorus removal is mainly completed through sludge discharge. The generation of a large amount of sludge not only causes secondary pollution, but also has extremely high investment and operating costs. How to effectively treat and dispose of a large amount of excess activated sludge has become a bottleneck in the development of modern sewage treatment plants.

The traditional biological treatment process represented by the activated sludge method is difficult to apply to the restoration of river courses and landscape water bodies
