Description
Technical field
The present invention relates to sewage disposal technology, be specifically related to the device and method that natural organic high-molecular flocculant is handled sewage/wastewater.
Background technology
The sewage or waste water that produces in production and the life is serious day by day to the pollution of environment, has progressively caused people's great attention.In the socioeconomic while of fast development, must strengthen protection to environment, become people's common recognition.For a long time, many engineering technical personnel are devoted to the processing research work of sewage or waste water, have proposed the treatment process and the equipment of multiple sewage or waste water.Biological process is arranged, physico-chemical processes is also arranged.Special-purpose treatment process is arranged, as the treatment process of the treatment process of the integrated conduct method of paper waste, leather-making waste water, dyeing waste water, municipal sewage treatment method etc., but the deficiency that exists is that investment is big, occupation of land is many, the time is long, working cost is high, the water quality inferiority after the processing; General method of wastewater treatment is also arranged, as Patent Office of the People's Republic of China on November 4th, 1998 bulletin number of patent application be 98102170, name is called " common waste water treating method ".This method is with lime or contain CaO or Ca (OH)
2Material and acid effect form throw out, in forming the throw out process and throw out adsorb after forming and carry charged impurity particle and electric neutrality impurity particle in the waste water secretly, realize various wastewater such as papermaking, printing and dyeing, food-processing, brewage, the sewage in trade effluent such as chemical industry, pharmacy, dyestuff, metallurgy and city domestic sewage and rivers, lake etc. handles.Waste water though supernatant water can reach emission standard, needs to consume a large amount of lime after this method is handled, and the big inconvenience of settled sludge quantity directly utilizes.
The content of invention
The device that one of purpose of the present invention is to provide a kind of natural organic high-molecular flocculant to handle sewage/wastewater, it need equipment few, take up an area of less, working cost is low, stable, has the ability of strong anti-shock loading;
The method that another object of the present invention is to provide a kind of natural organic high-molecular flocculant to handle sewage/wastewater, its technology is simple, easy and simple to handle, not influenced by temperature, and soil removability is strong, can reach emission standard after the sewage disposal, and the mud of generation can be made fertilizers for potted flowers.
Natural organic high-molecular flocculant of the present invention is handled the device of sewage/wastewater, comprise grating tank, the water collecting basin that communicates with grating tank, the equalizing tank that communicates with water collecting basin, the reaction tank adjacent, the settling tank that communicates with reaction tank, the filter-sterilized pond that communicates with settling tank, the clean water basin that communicate with the filter-sterilized pond with equalizing tank, the other sump pump that is provided with of equalizing tank, the water-in of sump pump stretches in the equalizing tank, water outlet is located in the reaction tank, is provided with the arm that adds natural organic high-molecular flocculant on the sump pump outlet conduit; Be provided with stirrer at reaction tank.
Natural organic high-molecular flocculant of the present invention is handled the device of sewage/wastewater, also comprise sludge thickener, pressure filter, inlet pipe communicates with sludge thickener with the mud pump outlet that equalizing tank and settling tank bottom communicate, and inlet pipe is corresponding with pressure filter with another mud pump outlet that the sludge thickener bottom communicates.
The grating tank that is used to dispose of sewage, water collecting basin, equalizing tank, reaction tank, settling tank, filter-sterilized pond, clean water basin, sludge thickener are arranged compact, equipment such as sump pump, stirrer, sludge pump, pressure filter are installed in corresponding position, to reduce floor space.
Natural organic high-molecular flocculant of the present invention is handled the method for sewage/wastewater, and its step is as follows:
Sewage/wastewater is introduced grating tank, remove bigger foreign material and floating matter after, enter water collecting basin, the silt particle that proportion is bigger in the sewage is fallen at the bottom of the pond, enter equalizing tank again and compile, regulate water quality, the water yield, be that next procedure keeps the stable water quality and the water yield;
Start sump pump with in the sewage suction reaction tank in the equalizing tank, and press the natural organic high-molecular flocculant that sump pump discharge capacity hourly adds 0.15-1.5 ‰, start the stirrer that is contained on the reaction tank simultaneously and stir, the add-on of flocculation agent is determined with different trade effluent water quality according to sanitary sewage.Add the radically reform natural organic high-molecular QH flocculation agent of environment protection treating Engineering Co., Ltd development of Chongqing, this flocculation agent is to extract macromolecular compound from plant, by grafting, draw hydroxyl, amido, carboxymethyl etc., be mixed with inorganics is compound again, add the electrostatic double layer that can compress the pollutent colloidal particle in the sewage rapidly, the formation net of building bridge is simultaneously caught, and fast pollutants in sewage is condensed into the bigger flock of density, rely on the action of gravity natural subsidence, remove pollutants in sewage.
Sewage enters settling tank after flocculation treatment, rely on action of gravity to fall Yu Chidi naturally, realizes solid-liquid separation, removes pollutent;
Enter the filter-sterilized pond through the supernatant liquor of post precipitation from the top of settling tank, the fine suspension Filtration Adsorption with residual enters clean water basin again;
From clean water basin, take a sample and detect, reach emission standard, can discharge or recycle.
The method of described natural organic high-molecular flocculation treatment sewage/wastewater, further comprising the steps of:
Mud is got rid of: respectively the mud of equalizing tank, settling tank bottom is evacuated to sludge thickener with sludge pump.
Mud concentrates: in sludge thickener, carries out, and from mud natural subsidence the pond that extract out equalizing tank, settling tank bottom, supernatant liquor flow automatically back equalizing tank, processing once more.
Sludge press filtration: with dewatering on the mud suction pressure filter of sludge pump with the sludge thickener bottom, the water that removes returns in the equalizing tank, handles once more.
Adopt present method to handle sewage/wastewater, speed of response is fast, technology is simple, and the treatment time is short, phosphor-removing effect is remarkable especially, can reach emission standard after the sewage disposal, and the mud of generation do not expand, nontoxic, can make the plant fertilizers for potted flowers.Be applicable to and handle various trade effluents and city domestic sewage.
