New microbial water treatment technology

2009-02-06View Original

Thread Content

A new microbial water treatment technology: The principle of natural purification involves spraying wastewater onto soil to trigger a corrosive reaction; this method, on the other hand, involves adding humus in dissolved form to the wastewater to induce the same corrosive reaction. This approach is the most significant feature of making full use of soil microorganisms in water treatment processes; it is what distinguishes it from the standard activated sludge method. Excessive aeration to enhance corrosion reactions is undesirable, and an anaerobic environment is also necessary. The basic principle of this method is to carry out intermittent aeration to promote corrosion reactions. Under anaerobic-anoxic-aerobic conditions, the contact of such mixtures causes organic wastewater to undergo processes of coagulation, combination, recondensation, and oxidation-reduction reactions, thereby removing unpleasant odors as well as nitrogen and phosphorus. Once the sludge is stabilized in a humified state, it no longer emits any unpleasant odors. Soil microorganisms Generally, soil microorganisms refer to the “Bacillus” genus. It is a type of saprophytic bacterium that actively participates in the decomposition of soil organic matter and the synthesis of humus. They are facultative or nearly facultative anaerobes. Its biological cycle involves widespread spread in nature, and it also propagates and reproduces in wood and forest soil, as well as in riverbeds and other areas. These microorganisms break down fallen leaves and dead wood, converting them into organic matter and minerals that are useful in nature, thereby nourishing new plants. Its nutrients flow into the ocean via rivers, nourishing marine life as well as seaweed and fish. Soil microorganisms are beneficial microbes that support the life cycle cycles in nature. Soil microorganisms in wastewater treatment: The metabolic products of soil microorganisms facilitate the recondensation reactions of organic substances in wastewater through bonding, coagulation, and polymerization, resulting in the formation of large molecules that aid in solid-liquid separation. Organic nitrogen, found in substances such as proteins and urea, as well as in ammonia and nitrogen in its inorganic form, produces an unpleasant odor during microbial decomposition. Its main components, NH3 and H2S, are used in the synthesis of proteins for cell reproduction, thereby being converted into acetic acid and amino acid polymer compounds. Stable polymer compounds are formed through the corrosive reactions between the metabolic products of active soil microbial communities and organic pollutants; these humic substances resulting from such corrosive reactions further enhance the metabolic activity of microorganisms. Through such metabolic activities, not only are organic matter and nutrients such as nitrogen, nitrogen, phosphorus, and phosphorus removed along with malodorous substances, but the sludge is also stabilized in a humus state, thereby improving concentration and dewatering efficiency, and preventing secondary decay of the dewatered sludge. In this way, the foul-smelling substances in the treatment plant are eliminated at their source, and an earthy scent is produced under the action of actinomycetes. Properties of soil microorganisms: 1. They can grow in alkaline wastewater (with a pH of 5.7 and 10% Nac1). 2. Heat resistance (7°C~45°C). 3. Spore formation allows the microbial community to maintain its activity even in harsh environments. ; Secretions are released during reproduction, improving water treatment efficiency. 4. Hydrogen sulfide and ammonia can be removed by reducing them to nitrous acid and inorganic sulfides. Principle of removing bad odors: Bad odors are by-products generated during the decomposition of proteins, amino acids, nucleic acids, and other substances found in organic materials. NH3, produced during the ammonification of proteins under the influence of ammonia, and H2S, generated during the inorganicization process, are the main substances responsible for bad odors.

It’s good, but isn’t the capacity to treat wastewater too low! How much soil is needed if there is a large amount of wastewater? And land resources are also valuable; isn’t it not enough to grow food? We still need to build houses, factories, schools, hospitals... I have an idea: could some wastewater be purified by being taken to the desert?

Is there a fundamental difference from traditional biochemistry?

I believe in this technology for the following reasons: 1. Microorganisms have a more favorable living environment in soil than in water; 2. Soil possesses adsorption properties that can prolong the time it takes for microorganisms to break down organic matter. There are also doubts regarding the widespread adoption of this technology: the selectivity and stability of microbial populations are key factors in its success. Additionally, it remains to be seen whether land resources are sufficient to meet the requirements of this technology

The traditional biological methods also originated from the self-purification processes in soil. I’m not sure what LZ means by \"soil corrosion reaction\" – isn’t soil treatment simply wetland treatment technology? Such technologies are mainly used for treating wastewater with low concentrations; they require large amounts of available land, along with various plants, and rely on the interactions among microorganisms, plants, and animals to purify the wastewater. Many such systems exist, especially in Europe and Australia, where there are successful examples of their use on a large scale – handling hundreds of thousands of tons of wastewater per day.

It has a nice name, but it’s actually an old thing. New things are not necessarily good; only those that are mature are good!

Many years ago, I used white-rot fungi to treat wastewater; I’m curious to know what everyone’s thoughts are on using white-rot fungi for wastewater treatment.

Hehe, if it really is a new technology, then the poster’s description is really poor. Anyway, I didn’t believe it at all after reading it.

Hehe, the limitations are too great; it’s very difficult to operate it considering our country’s conditions
