Abstract

The present invention is the biggest problem in the wastewater treatment facilities. The treatment efficiency is reduced due to the death of microorganisms caused by the toxic substance in the initial inflow of wastewater and the inflow of excessive sludge and the discharge of excess sludge and nitrogen. In order to solve problems such as eutrophication due to no removal of phosphorus, a separate stabilization tank (1) is installed at the front of the wastewater treatment facility to block the inflow of hardly decomposable substances and toxic substances into the aerobic treatment tank. In the latter stage, a ciliary immersion filter is installed in water, and the treatment efficiency is generated by the hydraulic pressure and the metabolic action of aerobic microorganisms attached to the nylon fiber yarns installed on the filter surface, and by the anaerobic microorganisms formed inside the filter. Treatment efficiency is generated through metabolic reactions, so biological and physical treatments are performed in parallel. Liege use. In addition, due to the drastic changes in wastewater and wastewater for one day, which are emerging as the biggest problems, the treatment efficiency of wastewater and wastewater is lowered and adversely affects water quality. Therefore, it is possible to adjust the flow rate by simple device setting and additional effects. We have developed a device that has an active countermeasure against the supernatant separation effect in the event of sludge flotation caused by sedimentation tanks, and aims for unmanned management of wastewater and wastewater treatment facilities, and also eliminates unnecessary facilities and minimizes the need for economic satisfaction. Its purpose is to increase the profits of consumers through the efficient management of wastewater and to increase the treatment efficiency of wastewater.

Description

Unmanned management-oriented wastewater treatment facility {.}

Economical treatment of users of wastewater treatment facilities by installing wastewater treatment facilities that require little maintenance, repair and management by eliminating the possible electronic control of wastewater treatment facilities and researching and developing treatment methods using natural principles. It aims at unmanned management to resolve the absence of management of small-sized wastewater treatment facilities, which is emerging as a big problem, and is intended to achieve smooth management by checking once a month.

The present invention is a wastewater treatment facility using anaerobic and aerobic bioprocessing, which is the main treatment process in the field of sewage and wastewater treatment, and the treatment of biological treatment process by equalizing the extreme flow fluctuation of 1 day using the principle of nature It is a method for treating wastewater that maximizes its capacity.In the past, it is mainly used to improve the performance of anaerobic or aerobic processes and to improve the treated water by using pumps (water, land, air lift pumps) or removing various organic substances and suspended solids. The sewage and wastewater treatment method, which focuses on technical skills, aims to improve the treated water, but the main effect is not achieved. In this method, a separate stabilization tank is installed at the front of the aerobic process, which is the main treatment process of wastewater, to reduce the initial inflow load, flow into the aerobic treatment tank, and install the aerobic treatment tank more than two divisions, so that the shear tank is filled with contact media and draft Indirect aeration type is selected by constructing a tube or aeration wall, and ciliary sedimentation filter is installed in post forging, and it is used for advanced treatment of wastewater as it is treated by aerobic and anaerobic microorganisms and physical treatment by filtration and adsorption. .

In addition, it is a method of maximizing the quality of treated water by flexibly equalizing the amount of wastewater discharged into the sedimentation tank for 24 hours using the flow control and the supernatant separation active sedimentation tank. In addition, through this method, the difficulty in leveling the overflow stream of the sedimentation tank is easily improved through this method, regardless of the conventional installation method, and it can be expected to have a great effect on the separation of the supernatant when sludge flotation occurs.

In addition, it is a groundbreaking treatment device that can be free from the causes of power consumption and breakdown caused by the use of a natural flow type method when introducing waste water into the main treatment system.

Wastewater treatment facilities to which the present invention belongs are toxic and hardly decomposable substances, which are the biggest disadvantages of existing wastewater treatment facilities.Inhibition of the activity of microorganisms when high concentrations of pollutants are introduced and degradation of treatment efficiency due to the death of microorganisms, and 1 It has a disadvantage that it is not possible to reduce the impact load of microorganisms caused by extreme inflow flow inequality of 24 hours a day. Therefore, sewage flowing into the wastewater treatment facility is filtered for advanced treatment, which is economical and easy to operate in anaerobic or aerobic processes. Equipped with adsorption and inflow flow equalizer, wastewater treatment can be performed more effectively.

The present invention is designed to install a pretreatment tank to remove toxic substances in biological treatment process of wastewater treatment facilities, and to install a special filter to remove surplus sludge, residual organic matter and nitrogen in effluent and evenly distribute the flow rate. Apply together. By installing an appropriate stabilization tank (approximately 1/4 of the flow control tank) and an inflow load stabilizer tube, which is an internal component, on the initial inlet of the wastewater, the toxic and hardly decomposable substances contained in the initial influent are separated or removed. After stabilization, the aerobic treatment tank (contact aeration tank), which is the main treatment device, is introduced. The aerobic treatment tank consists of two or more chambers, and the shear tank is installed with an aeration wall to avoid direct aeration from microorganisms and indirect aeration. The post forging uses a ciliary deposition filter to remove various untreated organic matter and fine flocks. Inlet from the clarification and supernatant separation active settling tanks. At this time, the flow control and separation of the supernatant active sedimentation tank is a device that can expect the flow control effect evenly because it discharges only a certain amount through the overflowware equipped with buoyancy port that reciprocates the up and down water. By simply adjusting the height of the buoyancy sphere, it is possible to contribute to public water quality by improving the treated water through leveling of the overflow stream, adjusting the flow rate, and separating the supernatant.

BEST MODE Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings.

The sewage and wastewater generated at each site are separated through the primary top barrier plate (2), bottom barrier plate (3) and the secondary top barrier plate (4) in the separate stabilization tank. Proceeds through the separation and enters the aerobic treatment tank through the tunnel-type stable pipe (5) installed on the inlet side of the aerobic treatment tank,

At this time, the lower part of the tunnel-type stabilizer is aerated by the diffuser 6, and various residual hardly decomposable substances and toxic substances are adsorbed into the aerobic chamber at low concentrations, thereby preventing damage to toxic substances. After stabilization, the influent sewage is treated in a front aerobic treatment tank, which is composed of two or more chambers, and treated by a cilia sediment filter (7) in a post aerobic treatment tank. Sewage flows into the pores of the ciliary immersion filter outer cylinder (9) equipped with yarns (8), and residual organic matter and suspended solids, which are not processed by activated carbon or porous ceramics (10) filled therein, are almost removed. The filtrate flows into the pores of the maternal immersion filter and flows out to the filtrate outlet 12. At this time, a large amount of microorganisms are inhabited by nylon fiber yarns on the filter surface, thereby obtaining biological treatment efficiency by microorganisms.

After such a long time, a blockage is generated in the filter. In this case, the effluent valve 13 installed at the filtrate discharge port side 12 is blocked, the backwash valve 14 is opened, and the backwashing by the blower is performed. As it proceeds, the fillings do not need to be replaced.

The wastewater passing through the ciliary deposition filter flows into the rectifier 16 along the sedimentation tank inlet 15 so that the flow of water flows downward by gravity and is evenly spread by the diffusion tube 17 under the rectifier 16. It is filled with the upper overflow 18 of the settling tank. At this time, the buoyancy sphere (19) attached to the overflow current (18) is rising or sinking in proportion to the amount of sewage to be introduced. That is, if the amount of inflow is large, a certain amount of inflow water flows through the V-groove of the overflow current (18). If the inflow is small, it sinks and overflows through the V-groove. Through this process, the treated water flowing through the overflow stream 18 flows into the soft rubber tube 22 through the overflow stream collection vessel 20 formed at the bottom of the flow stream and flows out into the forging.

The up and down reciprocating motion of the overflow stream creates a great efficiency in the supernatant separation effect when the sludge and the clarification water are formed on the surface, and the separation of the clarification water is difficult. It plays a key role in wastewater treatment.

The wastewater treatment facility equipped with the flow control and supernatant separation active wall outlet equipped with the tunnel type impact load stabilizer tube and sedimentary filter active sedimentation tank, which is a component of the rear end aerobic treatment tank, is a small scale. It can be used and applied to sewage treatment facilities, general single septic tanks, simple sewage treatment facilities, and all sewage and wastewater treatment facilities. The idea of the present invention described above does not need to be limited to a certain form or standard, and can be used by various methods in consideration of the conditions and conditions of the site, and may be installed redundantly to improve processing efficiency.

Example

The example applied to the wastewater treatment is shown in [Table 1].

If the above-mentioned flow rate adjusting device is installed in the sedimentation tank, which is a post-treatment tank, it is not necessary to install the storage tank (hereinafter referred to as the flow rate adjusting tank) necessary to adjust the flow rate of the inflow in the early stage of inflow. It is possible to achieve economical satisfaction because it is possible to construct a part of the structure that caused a large cost. In addition, because of the natural flow method, almost no discharge water incompatibility due to failure or carelessness can occur, and the double-wall overflow leveling and sludge and supernatant separation effects can be expected. You can expect

By simply using the ciliary deposition filter, the biological treatment effect by microorganisms and the physical effects such as filtration and adsorption by the porous contact media filled inside can be combined. It can be used for advanced processing of. Therefore, the above devices can contribute to the conservation of water quality in public water by realizing economical and rational wastewater treatment process that can benefit and benefit in many ways.
