Description
More particularly, the present invention relates to a sewage excellent comprehensive treatment method and a treatment system using the sewage excellent integrated treatment method and a sewage treatment method.
In general, water bodies (ie, water) such as stormwater, sewage, sewage, and wastewater are subjected to various water treatment processes such as filtration and sedimentation for the purpose of prevention of river pollution and use of high-grade water. In particular, as the industry diversifies and becomes more sophisticated, a large amount of pollutants are emitted in various fields. As population density increases, domestic wastewater also continues to increase.
Conventionally, the water treatment facility used in the water treatment facility is constructed and operated according to the substances to be treated and the use of the treated water.
Many treatment systems are currently being proposed for the treatment of sewage, wastewater (concentrated water). In most processing systems, biological treatment methods focused on removing organic matter were common. Now, many physicochemical treatment methods are being tried in parallel with membranes.
Biological treatment mainly uses organic biochemical metabolism of microorganisms to treat organic substances and suspended substances in the wastewater (concentrated water). For example, Korean Patent Publication No. 2003-84199 discloses a treatment method using a nitrifying microorganism cultured in anaerobic or aerobic digestive sludge.
However, the above-mentioned biological treatment occupies a large area and is vulnerable to fluctuations in the water quality and quantity of influent water, so maintenance is difficult, and unsanitary problems such as odor generation due to sludge treatment occur.
Physicochemical treatment uses physical phenomenon or chemical reaction, and there are methods such as pH control, filtration, oxidation / reduction, adsorption, ion exchange and the like. Physicochemical treatment is easy to maintain because it is possible to operate intermittently. However, the physico - chemical treatment method is mainly used as an auxiliary treatment means because the removal rate of organic substances, bacteria and fine particles is low.
In particular, as the industry diversifies and becomes more sophisticated, a large amount of pollutants are emitted in various fields. As population density increases, domestic wastewater also continues to increase.
Conventionally, the water treatment facility used in the water treatment facility is constructed and operated according to the substances to be treated and the use of the treated water.
In other words, there is a problem in that it can not achieve a complex effect while making a considerable investment because it builds facilities limited to specific hazardous substances.
Also, in the conventional water treatment facility, all the processes are performed uniformly irrespective of the required quantity of the treatment water corresponding to each process and whether or not the required water quality is met. Therefore, the water treatment process operation is not efficient and unnecessary cost is required.
Particularly, there is a problem that water treatment of a treated water in a state of high contamination takes a long time, and a driving load is increased and a treatment cost is increased.
In addition, when a single type of water in a specific place is treated with water, the cost of the water treatment process increases depending on the degree of contamination, the water treatment process takes a long time, the best water quality is difficult to obtain, and the water quantity is difficult to be secured.
A method for obtaining drinking water by treating surface water and ground water in such a water treatment facility is disclosed in Korean Patent No. 10-1109762 (water treatment method for obtaining water suitable for drinking or industrial water using river, river water, ground water, Processing apparatus).
In order to improve this, an improved surface water / groundwater water blending water treatment system and method for recovering water according to the use of the water by measuring the real time water quality and reducing the processing load for each process, as well as lowering and simultaneously treating the contamination degree by mixing multiple water sources Was developed by the present applicant.
However, wastewater treatment and stormwater are usually generated water sources, but systems such as surface water and groundwater treatment are not currently being developed and are inconvenient using separate treatment devices.
DISCLOSURE OF THE INVENTION The present invention has been made in order to solve the above-mentioned problems, and it is an object of the present invention to provide a sewage treatment system capable of simultaneously treating multiple sewage sludge, And a processing system using the same.
The sewage treatment water and the storm water are treated, and the sewage treated water having high pollution degree is mixed with the storm water to lower the pollution degree of the sewage water, thereby improving the water purification efficiency and improving the water purification efficiency.
The present invention relates to a
(S1) step of sewage treatment water and excellent water quality measurement to measure wastewater treatment water and storm water quality; (S2) a sewage-treated water blending tank into which the measured water-treated sewage water flows into the blending tank (200); If the water quality of the treated wastewater treatment water is worse than the reference value, if the water quality of the wastewater treatment water is poor, the rainwater may be introduced into the
The present invention can effectively treat sewage treatment water and stormwater in connection with a conventional water treatment system in which groundwater groundwater is treated by blending.
The pollution degree of the sewage-treated water can be lowered by blending the excellence, thereby reducing the water treatment efficiency and cost.

Flocs are called suspensions or suspensions in which solid particulates are dispersed, and when solid particulates in this state are aggregated with each other to form larger aggregates, they are called flocs. Usually aggregates of 0.1μ or more aggregates are called flocs. In some cases, colloidal particles smaller in size are aggregated aggregates.
Among the various flocculants, the most effective is the polymer flocculant. The flocculant used in the present invention is preferably a polymer flocculant, but other flocculants may be used.
The treated water that has passed through the
Since the colloidal material to be removed from the water purification plant is brown, it is difficult to precipitate. Therefore, as described above, when the flocculant is put into the
When the coagulant is added, the coagulant and the colloidal material are agglomerated by the rapid stirring to form micro flocs, and the micro flocs are agglomerated by the slow stirring to form large flocs. Therefore, sedimentation is removed by natural sedimentation.
The treated water of the
An Advanced Oxidation Process (AOP) is a process in which an OH radical (oxidation potential difference: 2.8 V) having a stronger oxidizing power than an oxidizing agent used in an ordinary oxidation process is produced in a reactor and the organic compound contained in the water is converted into CO2 It is decomposed into a harmless compound such as H 2 O or HCl. This makes it possible to treat better the degradable compounds contained in industrial wastewater.
In addition, the hydrogen peroxide ultraviolet
OH radicals are generated by photo-decomposing hydrogen peroxide in the simplest way in terms of OH radical generation, and ozone is 168 times more energy-absorbing than hydrogen peroxide, so that a relatively large amount of hydrogen peroxide Is required.
