Description

Wastewater Purification System

The present invention relates to a wastewater purification treatment apparatus which collects various moss or algae, etc. deposited in the flowing river water, and collects it to improve the water quality. The present invention relates to an apparatus for treating wastewater in a river runoff state which can increase the water quality improvement effect of effluent by allowing organic matter and sediment to be easily collected.

In general, wastewater and wastewater (hereinafter referred to as 'wastewater'), such as various kinds of domestic sewage and sewage, industrial wastewater, and livestock wastewater, are always purged because of environmental pollution, so that the biochemical oxygen demand (BOD) is discharged at the lowest level. To this end, water treatment facilities are mandatory in factories or apartment complexes that discharge various wastewater.

That is, livestock wastewater and industrial wastewater discharged from dyes and printing plants are discharged with a large amount of organic substances and colors that contaminate water. If the various wastewaters are discharged without purification, the natural environment is seriously polluted, such as the death of fish in the water, and the ecosystem is gradually destroyed.

And, once the ecosystem of the river is destroyed, it takes a considerable time to return to its original state, and there is a problem in that it takes a considerable cost to purify the polluted water.

Therefore, a lot of wastewater purification equipments are currently being developed. Looking at the structure of the wastewater purification equipment developed in the meantime, the structure of wastewater purification equipment developed in the meantime is mainly a pulverization tank for crushing suspended matter and contaminants (SS), an anaerobic digester and a rot tank for rotating wastewater, It consists of a filtration tank equipped with filtration stones, a sedimentation tank for sedimentation of sludge, and a disinfection discharge tank for discharging and discharging purified water.

When the wastewater purification process is carried out by the above configuration, the efficiency of the wastewater purification process enables to rapidly and continuously cultivate many aerobic microorganisms that lower the biological oxygen demand (BOD) of the wastewater in the contact oxidation tank. It can be said. In other words, it is possible to more efficiently remove suspended matter, contaminants, and chromaticity contained in the wastewater as it can increase the culture efficiency of aerobic microorganisms that lower the biochemical oxygen demand (BOD). It is.

In the wastewater hydrolysis purification process of anaerobic organic matter, the limiting rate step of anaerobic digestion is a methane fermentation step. It is a gaseous stage that transforms into a substance that is easy to ingest, which can vary depending on the device of anaerobic digestion.

The organic indicators used by researchers to assess the degree of anaerobicity in wastewater, depending on the type of substrate, are typically biochemical oxygen demand (BOD), chemical oxygen demand (COD), suspended solids (or sediment) mass (SS). ), But compared to total organic carbon (TOC), fatty acids, carbohydrates, it is almost impossible to compare all these types.

In particular, the activity of microorganisms is considered to be a very important item in the operation state and the initial operation state of digestion. In general, the activity of sludge can be measured by two methods. That is, the basic substrate degradation activity can be determined in the process state.

Such activity cannot be evaluated by representative microorganisms, and it should be based on measuring the effect state of influent toxicity according to the degree of activity, and there is a concern that the limit of methane decomposition step is exceeded due to lack of dissolved oxygen in the water quality. Therefore, the technology to supply dissolved oxygen to the waste water by using a fountain or air supply is mainly used.

However, in this case, the fermentation stage can be reduced, but there is a problem that green algae occurs due to the organic compound mixture, and especially a motor for driving a water fountain or blower installed in the water must be provided at all times to protect the motor from water. The device is essential, and when the diffuser is installed in the depth of water, its drainage pipe is not able to withstand the water pressure, and it is damaged very little. When the fountain is installed in the depth of water, it often breaks down. There was a problem that is difficult to use above the depth.

In addition, the continuous use of the water circulator without the filtration treatment is the same as the production plant of biochemical oxygen demand (BOD), chemical oxygen demand (COD), and mass of suspended solids (SS) as shown in the analysis table below. In this case, the state of nitrogen (TN) and phosphorus (TP) is maximized so that the water quality of the river becomes a river of death that can not live with the odor vibration.

Therefore, the present invention is to solve the conventional problems as described above, the object of the present invention is a purification treatment device of a simple configuration, it is possible to perform a good water purification, and can be used regardless of the depth of the river running water wastewater purification treatment To provide a device.

The purpose of the present invention as described above is the active seed culture (Bacteria bacteria) is cultured after the inflow of the river runoff and filled with quantitative; An active spawn quantitative injector and a precipitant quantitative injector installed in a line for discharging wastewater containing a large amount of spawn in the active spawn culture tank and operated as a sensor; A dilution tank installed to mix the influent with the active seed and the precipitant; A plurality of aeration tanks and settling tanks for aeration and sedimentation of the wastewater discharged from the dilution tank; A sludge treatment tank in which sludge is separated from the settling tank; This is achieved by addressing the discharge tanks in series and constructing a wastewater purification treatment device in a stream running state.

The present invention is to cultivate a large number of spawns in the soil culture apparatus in the active spawn culture tank into which the river runoff flows into the wastewater to decompose organic matter in the waste water quality into methane gas and carbon dioxide, and to grow aerobic bacteria If the suspended solids are removed by the organic filtration device after supplying oxygen, the waste water is effectively purified. The composition is simple, and the water quality of the stream can be well purified, and it can be used regardless of the depth of the river. It can be achieved.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings, which are attached to the accompanying drawings, as a preferred embodiment of the present invention.

1 is a schematic view showing a state in which the purification process by the present invention in order, the active seed culture culture tank 10 in which the active seed is cultured after the inflow of river water is filled in quantitatively; In the active spawn culture tank 10 is installed in a line for discharging the wastewater containing a large amount of spawn, and the active species is cultured to detect the flow of the river wastewater containing a large amount by a known sensor 13 to the converted signal An active spawn quantitative injector 11 and a precipitant quantitative injector 12 operated according to the method; A dilution tank 20 for mixing the influent with active seed and precipitant; A plurality of aeration tanks 30 and a settling tank 40 for aeration and sedimentation of the wastewater discharged from the dilution tank 20; A sludge treatment tank 50 for separating sludge from the settling tank 40; The sludge is separated and disinfected purified water to finally discharge the discharge tank (60) is characterized in that the wastewater purification treatment device in the stream running water configuration.

In the structure of the present invention, the active spawn culture tank 10 is a flow rate control valve (not shown in the drawing) is installed so that the flow of the river flows in an appropriate amount at all times, and the bioactive agent of 15% of the surfactant active Various species by the soil bacteria growth of 45% of ceramic (ocher) are multiplied by the genetic method to photosynthesize. The active spawn cultured in the active spawn culture tank 10 is a non-toxic, non-infectious special active bacterium, so that the biodegradability of 99.7 is saponified to decompose organic matters and even sodium salts.

Then, the active spawn is cultivated as described above, and while the river wastewater containing a large amount is introduced into the dilution tank 20 by a transfer means such as a pump, the active spawn amount is appropriate as a signal of the sensor 13 which detects the inflow of the waste water. The injector 11 and the precipitant injector 12 are operated to supply the active seed and the precipitant to be introduced into the dilution tank 20 together with the wastewater.

At this time, in the dilution tank 20, as shown in FIG. 2, the stirring blade 23 and the air injection pipe 24 rotated by the motor 21 are installed to be controlled by the control box 23, respectively. And when the precipitant is diluted when the air bubbles are mixed and burst, it can be said that the stirring power is increased and the culture of aerobic microorganism is promoted.

In addition, in the upper end of the front aeration tank 30 of the plurality of aeration tanks 30 installed in the lower dilution tank 20, the screen filter 31 is installed at a predetermined height as shown in Figure 3 to the control box 32 When the wastewater introduced from the dilution tank 20 is pumped to the screen filter 31 by the controlled pump 33, impurities in the stream wastewater are filtered and then installed to fall into the aeration tank 30.

Only then, large particles of impurities contained in the stream wastewater cannot be filtered out, and only a small number of particles pass therethrough, thereby improving the purification efficiency of the wastewater.The stream waste water is filtered by the screen filter 31 and then aerated at a predetermined height. Aeration is caused by a large amount of air bubbles naturally occurring when falling to the 30, the aeration tank 30 may be provided with a plurality of air diffusion pipe 34 for supplying air separately.

And, when installing a plurality of aeration tank 30 and the settling tank 40, as shown in Figure 4, the stream wastewater is passed through a plurality of aeration tank 30 in order to pass through the settling tank 40 again in a zigzag order to be discharged. This is preferred.

Here, the aeration tank 30 is aerobic dilution, decomposition, and stirring adjuvants and influent water is one physical property, that is, saponification is good biodegradation occurs as the deodorization is performed first, and the enzyme is generated second The fermentation is started in the third order, and the organic matter is decomposed and destroyed by methane gas and carbon dioxide, and the inorganic matter is aggregated.

In addition, it has the effect of improving the work efficiency of decomposing organic matter while passing through a plurality of aeration tanks 30 in turn, and in the case of installing the air diffusion pipe 34 in the aeration tank 30, the pipes of different diameters are installed in parallel in sequence At this time, it is preferable to install the air diffusion tube 34 to enter about 30cm from the water surface, so that it can be said that the decomposition of organic matter is optimally achieved.

Then, when the stream wastewater aerated in the aeration tank 30 flows into the sedimentation tank 40, sludges that are precipitates through the sediment recovery pipe connected to the float recovery pump while the waste water passes through the plurality of sedimentation tanks 40 are sludge treatment tanks 50. In the sedimentation tank 40 at the rear, only the purely purified water is discharged. At this time, the discharged water has a very low content of nitrogen (TN) or phosphorus (TP), but has a biological oxygen demand (BOD) of 4.0. It is discharged in the state purified to the following favorable water quality.

The present invention as described above in the configuration of the wastewater purification treatment device in the stream running water state, since the accompanying drawings show only one embodiment, the shape of the configuration may vary as necessary. The present invention is a simple and good configuration of the water can discharge the purified water quality, and can be used regardless of the depth of water, especially the flowing water is a very excellent effect to purify the stream running water, It is a very useful design with low maintenance cost because the process is quick and easy, which can significantly reduce the manpower and cost required to purify the waste water.
