Description

4 STEP TREATMENT APPARATUS OF ORGANIC AND WASTEWATER FOR HIGH CONCENTRATION AND METHOD THEREOF}

According to the present invention, the organic and inorganic wastewater for co-treatment of various wastewaters in accordance with the co-integration of water environment treatment is to be combined with the sewage by combining the physical and biological methods in four stages. In the case of the first step treatment facility of the crude wood scrubber and flow control tank that physically removes sand, seeds and unsaturated substances, it is merged with sewage, and the first stage treatment when linking wastewater with 1% of sewage, and the fine solids and small molecules are dissolved. Fine solids remover with PH adjustment to remove solids and additional equipment to add polymer coagulant, two stages process to storage tank, digester to remove polymer oil and inorganic residues after treatment, microbial generation immersion tank, After the three-stage treatment of biological methods such as organic and inorganic recovery, chemical oxidation tank, filtration tank, etc., it should be linked to sewage treatment plant. In the case of single discharge in the absence of conditions, after the three-stage treatment, after the ozone contact and magnetic magnetization treatment, the four-stage advanced treatment through the organic / inorganic condensation separation tank and the filter is performed to treat the specific wastewater discharged water quality conditions. The present invention relates to a high-level organic and inorganic wastewater (sewage-related) four-stage treatment apparatus and method thereof.

Conventional high-concentration organic and inorganic wastewater treatment has a certain size of tank in the input tank to naturally settle the heavy collapsing solids and then remove them every fixed time, and the overflow water flows into the crude wood scrubber remover to remove the colloids of more than 8mm and then separates the separation liquid. After storing in the first reservoir, the fine stencil remover is removed by a pump, and the fine stencil of 2 mm or more is removed and then transferred to the primary treatment process. As described above, the conventional pretreatment process does not include high concentration of organic and inorganic wastewater which can be removed from pretreatment except phosphorus manure, and most of the fine particle solids and dissolved solids of 2 mm or less are not effective. As described above, when the pretreatment is introduced into the primary treatment process after the pretreatment, the fibrous and unsaturated substances, which have not been removed in the pretreatment step, rise to the upper part of each treatment tank to form scum and block degassing. Particle size solids such as mucus and small seeds, and food waste are deposited in each tank and digester to reduce the volume load, and the treatment efficiency does not increase even after long-term treatment due to the pre-treatment of microorganisms. In addition, the minerals deteriorate in the treatment plant environment, and deteriorate the environment of the treatment plant. Also, the organic and inorganic substances are not decomposed and remain in the colloidal state. Therefore, the treatment water quality tends to deteriorate in the primary treatment process. Dilution concept due to excessive sediment and scum and inability to grow microorganisms In the existing oxidative digestion treatment method, low molecular solids of minerals are settled, and polymer solids of organics remain undecomposed even after the first treatment for a long time and are transferred to the next process. Due to the high chemical costs and long-term treatment, the treatment of untreated water is unstable, the treatment period and facility costs are high, and the maintenance is difficult.

In the present invention, regardless of the properties and seasonal conditions of the high concentration of oil and inorganic wastewater, the first step of physically remove the particulate solids and low-molecule dissolved solids in the high concentration influent in the digestion tank and microbial generation immersion tank to fit the biological treatment water quality By decomposing digestion and microbial production in a short time, the suspended suspended particles and polymer dissolved organic and inorganic materials are decomposed reliably and then flowed into the advanced processing stage to stabilize and discharge. It has the advantage of maintaining a pleasant environment by completely enclosing operation of two-stage physical treatment equipment, and managing joint water treatment facilities under each treatment stage facility to meet the quality of merged water in sewage-related treatment, and by batch automatic process operation. Selective application of high concentration organic / inorganic wastewater with minimal maintenance The present invention provides a high-level organic and inorganic wastewater (sewage-linked) four-stage treatment apparatus and method for the treatment to ensure stable treatment plant operation.

Abandoned storage is obtained to obtain a third stage treatment process in which the amount of sewage treatment 1% is combined with sewage.

The third stage treatment shown in FIGS. 1 and 4 is carried out in a fixed quantity tank by transferring the digestion tank transfer pump 3-1 connected to the bottom of the second stage storage tank 2-6 to the improved facility tank 3-2. Magnetic constant temperature pump (3-3), which allows to stay in digestion tank (3-3) for a long time, gives up air volume suitable for microorganisms with three-stage broo (3-4) at the bottom of each tank, and sucks in tank bottom on the side of rectangular digester (3). -5) are installed and discharged from the surface of the tank to induce decomposing organic matter and polymer organic matter to induce bubbles, and the upper part of the closed digester is formed with a rectangular lid male hole protruding from the tank surface.
