Abstract
A purifying device for organic wastewater with high-concentration inorganic salt is mainly composed of the following components: an absorber, a multiple-effect evaporator and an aeration biological filter. The absorber is connected with the multi-effect evaporator. The multi-effect evaporator is connected with the aeration biological filter. The organic matter in the wastewater is removed through the absorber. The multi-effect evaporator recycles crystal salt from the salt in the wastewater through a multi-effect pressurized evaporation process. After condensation and cooling, the multi-effect evaporated steam and volatile organic compounds enter the aeration biological filter again. Through the function of microorganism, the organic matter is converted to carbon dioxide, water, inorganic salts, etc. for further reducing COD and BOD in the water and ensuring the purification of wastewater. The beneficial effect of the purifying device for organic wastewater with high-concentration inorganic salt is advantageous in that: the absorber is adopted for removing partial organic matters in the high-salinity organic wastewater; the BOD and COD in the wastewater is reduced through multi-effect evaporation desalination; the organic compounds are converted to carbon dioxide, water, inorganic salts, etc. through the function of microorganism in the aeration biological filter; the COD and BOD in the water is further reduced, and the purification of wastewater is ensured.
Description
Technical field
The utility model relates to a kind of organic wastewater purifying device that contains the high density inorganic salt, belongs to the sewage treatment equipment technical field.
Background technology
China is the country of a water resources poorness, is again a with serious pollution country of water, and industrial development causes a lot of social environment problems, and trade effluent is exactly one of them.Some paper-making industries, dyeing industry and pesticide industry are in process of production, produce the organic waste water of supersalinity, the high density inorganic salt mainly are cytolemma and endobacillary enzymes by the environment osmotic pressure destroy microorganisms that raises to the toxic action of wastewater treatment, thereby destroy microorganisms is to the purification of waste water.
Handle brine waste at present and mainly contain following several method: one, improvement fresh water microorganism: the microorganism of this method improvement is limited to the tolerance range of salinity, and to the variation sensitivity of environment, when the salinity environmental change, the adaptability of microorganism can disappear at once, Gai Liang microorganism feature does not have heredity simultaneously, needs repeatedly improvement; Two, dilution influent concentration: water inlet is diluted, make salinity be lower than malicious thresholding, biological treatment just can not be suppressed, but this method has increased running cost, waste water resource; Three, utilize halophile: it is a kind of effective ways that this method is handled high salinity waste water, but its shortcoming is that start time is long, in earlier stage the start-up cost height.
Summary of the invention
The purpose of this utility model is to overcome the deficiency of above-mentioned existence, provides a kind of with low cost, easy to use, handles the high refining plant of high salinity waste water efficient.
The purpose of this utility model is finished by following technical solution, a kind of organic wastewater purifying device that contains the high density inorganic salt, and it mainly is made of adsorber, multiple-effect evaporator and BAF, and described adsorber connects multiple-effect evaporator; Described multiple-effect evaporator connects BAF.Remove organism in the waste water by adsorber; Multiple-effect evaporator is with the evaporative process recovery xln salt of the salt in the waste water by the multiple-effect pressurization, the steam of multiple-effect evaporation and volatile organic matter are through condensation, enter BAF after the cooling again, pass through action of microorganisms, organism is converted to carbonic acid gas, water and inorganic salt etc., further reduce COD and BOD in the water, guaranteed the purification of waste water.
Described BAF adopts the U-shaped structure, and every section filler does not disturb mutually independently carrying out work in the element cell, and stable effluent quality is convenient for changing.
Described multiple-effect evaporator is a triple-effect evaporator, and the evaporative process of crossing the multiple-effect pressurization reclaims xln salt, can reduce the COD in the waste water simultaneously.
The beneficial effects of the utility model are to adopt adsorber a part of organism absorption in the organic high-salinity wastewater can be removed, by the multiple-effect evaporation desalination low BOD and COD in the waste water, by action of microorganisms in the BAF, organism is converted to carbonic acid gas, water and inorganic salt etc., further reduce COD and BOD in the water, guaranteed the purification of waste water.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is done detailed introduction: as shown in Figure 1: a kind of organic wastewater purifying device that contains the high density inorganic salt, it mainly is made of adsorber 1, multiple-effect evaporator 2 and BAF 3, and described adsorber 1 connects multiple-effect evaporator 2; Described multiple-effect evaporator 2 connects BAF 3.Waste water enters adsorber 1 by water-in 7, removes organism in the waste water by adsorber 1; Enter the inlet 9 of multiple-effect evaporator 2 then, multiple-effect evaporator 2 is with the evaporative process recovery xln salt of the salt in the waste water by the multiple-effect pressurization, discharge by salt outlet 6, the steam of multiple-effect evaporation and volatile organic matter are through condensation, enter BAF 3 after the cooling again, by action of microorganisms, organism is converted to carbonic acid gas, water and inorganic salt etc., further reduce COD and BOD in the water, guaranteed the purification of waste water.
Described BAF 3 adopts the U-shaped structure, and every section filler does not disturb mutually independently carrying out work in the element cell, is convenient for changing, and stable effluent quality is discharged from water outlet 8.
Described multiple-effect evaporator 2 is a triple-effect evaporator, and the evaporative process of crossing the multiple-effect pressurization reclaims xln salt, can reduce the COD in the waste water simultaneously.
