Description

The present invention relates to a facility for eradicating urine, septic tanks, sewers, sludge and food residues by microorganisms.

The treatment method of the conventional sewage treatment facility is the activated sludge method, and the method of activating the aerobic bacteria in the sewage by performing the aeration operation has a major drawback, and as a result, excess sludge is produced.

In order to expedite the separation of individual liquid wastewater, flocculants are used, and the settled sludge is drawn out and dewatered, and the incinerated ash is disposed of in landfills, or reduced by fertilization and methane fermentation. However, it is impossible to completely disappear.

As mentioned above, sludge cannot be completely extinguished, a large amount of oil is consumed for its treatment, CO2 is emitted to help warming, and waste that spends money on what should be discarded is solved. .

The purpose of this treatment facility is to realize the complete elimination of excess sludge, which could not be solved by conventional treatment methods.

Microorganisms to solve the above problems Wastewater and sludge extinguishing facility methods are: raw water (1) water storage tank (2) conditioning tank (3) decomposition tank (4) 4 tank, decomposition digestion tank (8) 4 This is a multi-stage multistage structure consisting of 19 tanks, consisting of 17 tanks, 2 tanks for digestion tank (12), 17 tanks for digestion extinction tank (14) and 2 tanks for muddle reaction extinction tank (18). The treatment process is performed by the process of individual liquid separation → fermentation → decomposition → digestion.

This system uses the function of soil fungi (intermediate fungi), is a treatment facility that compactly integrates the work of soil, has no bad odor or danger to human livestock, and is the final treatment that does not generate excess sludge, the most effective It is a simple processing method.

The raw material that becomes the fungus bed is cedar, and the portion that becomes the fungus bed of the cedar is crushed by a special method, and when the spoiled part is removed over time, a stable cellulose remains. This cellulose can be an excellent bio-cedar chip that is very comfortable for microorganisms to live in. The inherent characteristics of this chip are as follows: (a) It has an organic substance adsorption function due to the processing of making it porous. (B) Promote the growth of microorganisms. (C) Enable biodegradation. (D) Deodorizing effect. (E) Don't rot. (F) Adjust the humidity to 63%.

As a raw material for the fungus bed, a carrier having a unique shape in which an enzyme is kneaded with polypropylene is used as the fungus bed as in the case of cedar chips. By contacting this carrier packed in the tank, it is decomposed and digested by anaerobic, aerobic and amphoteric bacteria adsorbed on the carrier.

Effective use of cedar chips, a polypropylene carrier and intermediate fungi as a fungus bed, and operation of an enzyme active solution supply device, a cell membrane decomposition device, and a fermentation bacteria culture device to stabilize and propagate the decomposed bacteria. By adjusting these, digestion is performed and sludge disappears.

As mentioned above, since sludge disappears at the treatment facility using this system, it is not necessary to use oil for drying and incineration, so it is good for the environment without emitting CO2. It also saves money from wasting money.

This treatment facility can be installed according to the local circumstances and business form, has a low construction cost, is easy to maintain and is economical.
