Description
Technical Field
The invention relates to the technical field of sewage treatment, in particular to a high-efficiency sewage treatment system and a high-efficiency sewage treatment method.
Background
With the continuous and rapid development of urbanization and industrialization, the water environment in China is seriously damaged and tends to be continuously deteriorated. The sewage discharge not only seriously affects the daily life of residents, but also destroys the ecological balance of the nature. In order to reduce the discharge amount of sewage, sewage treatment plants are established in various parts of the country, however, the problems of overlarge electric energy consumption, high operation cost, secondary pollution caused by byproducts and overproof effluent caused by improper operation control exist in the sewage treatment process for a long time, so that the significance of researching the optimization control of the operation process of the novel sewage treatment process to realize energy conservation and consumption reduction is great, and the method is a necessary development trend of the sewage treatment industry in the future.
Currently, the most common sewage treatment method is mainly an activated sludge process, which is a sewage treatment method for removing organic pollutants in sewage by utilizing the coagulation, adsorption, oxidation, decomposition, precipitation and other actions of activated sludge in sewage. The filler is added into the biochemical pool, the sewage is in wide contact with the microorganisms on the filler, and then the pollutants in the sewage are removed through the metabolism of the microorganisms, so that the sewage is purified. The method has low total decontamination efficiency and long time consumption for sewage treatment, so that the treatment period is integrally prolonged, and the method is not beneficial to the rapid treatment of sewage. In addition, the biological treatment system is only dependent on the decomposition action of microorganisms, has low speed and is not easy to take effect quickly, and has the common problems of easy sludge expansion, poor impact resistance on water quality and water quantity and the like; moreover, the treatment efficiency of the system is closely related to the microbial activity, so that a large amount of excess sludge is inevitably generated in the process of treating sewage by a biological method, and how to treat the excess sludge becomes a new problem.
For example, the activated sludge process has significant problems: the aerobic tank converts ammonia nitrogen into nitrate nitrogen to provide raw materials for the anoxic tank, and simultaneously removes more organic matters, and methanol is additionally added due to lack of carbon sources during denitrification reaction of the anoxic tank, so that COD (chemical oxygen demand) of effluent is easy to exceed the standard, and the medicament cost, sludge yield and sludge treatment cost are also easy to increase.
Generally, the operation cost of the sewage treatment process adopting the microorganisms is relatively low, and carbon circulation and nitrogen circulation of organic matters are really realized; however, the treatment process is complicated, and the operation parameters need to be adjusted according to various factors in different treatment stages to maintain the stability of the living environment of the microorganisms and remove the corresponding organic pollutants, and by-products such as: excess sludge, hydrogen sulfide, nitrous oxide and the like are easy to cause secondary pollution to the environment, and have certain defects.

However, those skilled in the art will readily recognize that some of the features may be omitted or replaced with other elements, materials, methods in different instances. In some instances, certain operations related to the present application have not been shown or described in detail in order to avoid obscuring the core of the present application from excessive description, and it is not necessary for those skilled in the art to describe these operations in detail, so that they may be fully understood from the description in the specification and the general knowledge in the art.
Furthermore, the features, operations, or characteristics described in the specification may be combined in any suitable manner to form various embodiments. Also, the various steps or actions in the method descriptions may be transposed or transposed in order, as will be apparent to one of ordinary skill in the art. Thus, the various sequences in the specification and drawings are for the purpose of describing certain embodiments only and are not intended to imply a required sequence unless otherwise indicated where such sequence must be followed.
The numbering of the components as such, e.g., "first", "second", etc., is used herein only to distinguish the objects as described, and does not have any sequential or technical meaning. The term "connected" and "coupled" when used in this application, unless otherwise indicated, includes both direct and indirect connections (couplings).
For clear and accurate understanding of the technical solutions of the present application, some technical terms are explained herein.
The COD parameter, Chemical Oxygen Demand (Chemical Oxygen Demand), is a Chemical method for measuring the amount of reducing substances to be oxidized in a water sample. Under a certain condition, the water sample takes the amount of an oxidant consumed by oxidizing reducing substances in 1 liter of water sample as an index, and the amount is converted into milligrams of oxygen required after each liter of water sample is completely oxidized and is expressed by mg/L. The COD level reflects the degree of contamination of water with reducing substances, and generally, the higher the COD level, the more serious the water contamination. Usually the COD parameter is measured by a COD sensor.
The TN parameter, Total Nitrogen (Total Nitrogen), is the Total amount of various forms of inorganic and organic Nitrogen in water, often including NO3-、NO2-and NH4+ and other inorganic nitrogen and protein, amino acid and organic amine and other organic nitrogen in mg nitrogen for each liter of water. The TN amount is often used to indicate the degree of nutrient contamination of the water, and the higher the value is, the more serious the water quality contamination is. Typically, the TN parameters are measured by TN sensors.
The TP parameter, Total Phosphorus (Total Phosphorus), is the sum of the Phosphorus present in the wastewater in both the inorganic and organic states. The TP amount is one of indexes for measuring the water pollution degree, and the larger the value is, the higher the water pollution degree is. Typically the TP parameters are measured by a TP sensor.
NH3the-N parameter, namely ammonia nitrogen concentration, the content of ammonia nitrogen is an important standard for measuring water quality, and the content of ammonia nitrogen is expressed in milligrams per liter, if the content of ammonia nitrogen is high, eutrophication of the water body can be caused. Usually NH3The N parameter is represented by NH3-N sensor measurements.
The pH parameter refers to the ratio of the total number of hydrogen ions in the wastewater to the total amount of substances, and is usually pH value. Typically the pH parameter is measured by a pH sensor.
The DO parameter, dissolved oxygen concentration (dissolved oxygen), is the amount of oxygen dissolved in water and is an indicator of the self-cleaning capacity of a body of water expressed in milligrams of oxygen per liter of water. The DO amount has a close relationship with the partial pressure of oxygen in the air and the temperature of water, and in a natural situation, the oxygen content in the air does not change greatly, so that the water temperature is a main factor, and the lower the water temperature is, the higher the content of dissolved oxygen in the water is. However, when the water body is polluted by organic matters, oxygen is consumed seriously, dissolved oxygen cannot be supplemented in time, anaerobic bacteria in the water body can be propagated quickly, and the water body becomes black and smelly due to the corruption of the organic matters, so that the water body is seriously polluted, the self-cleaning capacity is weak, and even the self-cleaning capacity is lost.
The ORP parameter, i.e., Oxidation-Reduction Potential (Oxidation-Reduction Potential), is used to reflect the macroscopic Oxidation-Reduction property of all substances in an aqueous solution by reaction, and the higher the Oxidation-Reduction Potential is, the stronger the Oxidation property is, and the lower the Potential is, the weaker the Oxidation property is. The ORP quantity is taken as a comprehensive index of the environmental condition of the medium, which represents the relative degree of the oxidability or reducibility of the medium, and can not independently reflect the quality of water quality, but can comprehensively reflect the ecological environment in the aquarium system by combining other water quality indexes. Usually, the ORP parameter and the DO parameter are measured by an integrated multi-parameter sensor.
H2The S parameter, i.e., the concentration of hydrogen sulfide, is used to reflect the content of the sulfider gas in the space. Generally, the anaerobic fermentation process can be divided into a hydrolysis stage, an acidification stage, an acid decline stage and a methanation stage, and hydrogen sulfide and methane gas are sequentially generated in the last two stages, so that the detection of the content of hydrogen sulfide gas at any time is helpful for judging the proceeding state of anaerobic fermentation, and the anaerobic fermentation is controlled to be maintained in the hydrolysis stage and the acidification stage.
The sludge level parameter is the height of the sludge at the bottom after the sludge is settled in the structure. Usually, the mud level parameters are measured by an ultrasonic mud level meter.
The application mainly relates to a high-efficiency sewage treatment system and a high-efficiency treatment method thereof, and the invention conception of the technical scheme is as follows: based on artificial intelligent accurate regulation and control, the stable reaction environment of each link in the sewage treatment process is maintained, and different types of biological enzymes are directly applied to participate in the biochemical reaction process of sewage treatment, so that a new sewage treatment process is formed, the controllability in the sewage treatment process is improved, the biochemical reaction efficiency and the denitrification effect in the sewage treatment process by the biological process are improved, byproducts generated in the sewage treatment process are reduced, the secondary pollution of the byproducts to the environment is avoided, and the pressure of solid waste treatment and atmosphere treatment is reduced.

The chemical adding device 16 is arranged at the inlet end of the aerobic tank 12 and is used for adding chemical at the inlet end and adjusting the alkalinity of the sewage. The chemical adding device 13 may have functions of preparing a chemical, controlling the amount of the chemical to be added, and the like, and may be configured to prepare and add a chemical such as a sodium carbonate solution or a caustic soda. Generally, the types of medicines which can be prepared comprise acid, alkali, oxidant, reducing agent, carbon source, disinfectant and the like, powdery, granular or blocky medicines generally need to be dissolved and then prepared into solution with a certain concentration and then quantitatively added by using a metering pump, gaseous medicines need to be mixed and compressed with water and then quantitatively added by using the metering pump, the medicines in a solution state can be diluted into solution with a certain concentration or directly added by using the metering pump, and the powdery medicines which are partially insoluble in water can be directly added by using a conveying screw, a pneumatic conveying pump or a hopper. In this embodiment, when the adding device 16 adds the sodium carbonate solution at the inlet end of the aerobic tank 12, it is not only beneficial to adjust the sewage entering the aerobic tank 12 to reach a slightly alkaline state (such as a pH value of 7-8), but also beneficial to provide a sufficient carbon source for the anoxic tank.

It is noted that the anaerobic fermentation process can be divided into four stages, namely a hydrolysis stage, an acidification stage, an acid decay stage and a methanation stage. And the reaction process is controlled in two stages of hydrolysis and acidification in the hydrolysis acidification tank. In the hydrolysis stage, the combined filler can degrade solid organic substances into soluble substances and degrade macromolecular organic substances into micromolecular substances; in the acidification stage, organic substances such as carbohydrates are degraded into organic acids, mainly acetic acid, butyric acid, propionic acid and the like. The hydrolysis and acidification reactions proceed relatively quickly and it is generally difficult to separate them, the main microorganism at this stage being the hydrolysis-acidification bacteria. The biodegradability of the sewage can be improved after the sewage passes through the hydrolytic acidification tank, the pH value of the sewage is reduced, and the sewage is reducedThe mud yield creates favorable conditions for subsequent aerobic biological treatment. As can be understood by those skilled in the art, after the sewage is treated by the hydrolysis acidification tank, on one hand, the biodegradability of the wastewater can be improved, and macromolecular organic matters can be converted into small molecules; on the other hand, COD in the sewage can be removed. In order to avoid anaerobic fermentation from entering the latter two stages (in which hydrogen sulfide and methane gas are generated successively), it is necessary to place a hydrogen sulfide sensor (i.e., H) below the heat-insulating sealing cover of the hydrolysis acidification tank and above the water surface2And the S sensor) is used for detecting the concentration change of the hydrogen sulfide in the gas, so that the water inflow, the sludge discharge, the intermittent small-amount aeration stirring time and the water temperature (30-35 ℃) of the hydrolysis acidification tank 21 are controlled by the processor 17 and the controller 18, and the optimal treatment effect of the hydrolysis acidification tank is ensured.
It should be noted that, since the sewage output from the hydrolysis acidification tank 21 is acidic, the reaction in the lime filter tank can occur: CaCO3+H+→Ca2++HCO3-，Ca2++PO4 3-→Ca3(PO4)2↓. Therefore, phosphate dissolved in the sewage can be removed, the pH value is increased and maintained at 7-8, and alkalinity is provided for nitrosation reaction in the aerobic tank 12. In addition, the lime filter 22 can absorb suspended matters and sludge in the sewage at the same time, and reduces the strain pollution to the aerobic tank 12 and the anoxic tank 13.

For example, after analyzing the wastewater to enter the acid decline stage, the controller 18 may adjust the following: such as increasing the flow of sewage into the hydrolysis-acidification tank 21, increasing the discharge of sludge from the hydrolysis-acidification tank 21, decreasing the aeration time of the hydrolysis-acidification tank 21, increasing the stirring time of the hydrolysis-acidification tank 21, increasing the flow of backwash wastewater in the backwash device 23, or increasing the dosage of alkaline chemicals (e.g., lime) in the lime filter 22. The aeration time influences the amount of oxygen, so that hydrolytic acidification is maintained in an aerobic and anaerobic intermediate stage, and acetogenic bacteria and methanogenic bacteria can be inhibited in an aerobic environment.
