The micro-pollution of water source caused by the natural or artificial activities is the one which can not be treated by the traditional tap water treatment process. The filtering material filtered in the traditional treatment process is mainly filtered by sea sand, when the water quality and organic matters are excessive and the mud in the water body is excessive in flood season, in addition, if a large amount of eucalyptus drainage liquid flows into the raw water and the manganese ions in the water body exceed the standard, the sea sand filtering material in the traditional process is hardened for 2 days at most, and the filtering effect is lost. Even if the sea sand in the valveless sand filtration under the condition of the pretreatment flocculation process is hardened in less than one week, the sea sand cannot be backwashed after being hardened, so that the filtration effect is lost, sand change and labor cost are increased for a water works, the cost in operation is increased, and the effluent quality cannot be ensured.

Detailed Description
The present invention is described in further detail with reference to fig. 1-2.
The source water sequentially passes through a microbial ecological pool 1, a multi-medium filter tank 2, a precision filter 3, a water molecule cutter 4 and a sterilizer 5 to obtain purified water meeting the drinking water standard; the microbial ecological pool 1 is provided with a porous floating bed consisting of PVC pipes and a porous net, and aquatic weeds are planted in holes of the porous floating bed. 2-3 aquatic weeds are planted in each hole; a hanging curtain and an aeration system which are composed of a plurality of nanofiber carriers are arranged in the microbial ecological pool 1; the nanofiber carrier is in a strip shape, and two ends of the nanofiber carrier are respectively fixed at the bottom of the porous floating bed and the bottom of the microbial ecological pool 1; the multi-medium filter tank 2 is a three-stage filter tank, and sequentially comprises a first-stage filter tank, a second-stage filter tank and a third-stage filter tank; the medium in the first-stage filter tank is zeolite mineralized sintered balls, the medium in the second-stage filter tank is volcanic mineralized sintered balls, and the medium in the third-stage filter tank is medical stone mineralized sintered balls. The sterilizer 5 is a nano electro-optical sterilizer.
The water passing through the disinfector 5 flows into a clean water tank and then is supplied to a water tower for blending.
The working principle of the invention is as follows: 1. the aquatic weeds can release a large amount of oxygen in the water body through photosynthesis, increase dissolved oxygen in the water, inhibit the growth of harmful algae, and quickly construct an implantation bed of microorganisms on root systems to accelerate the growth and the propagation of indigenous strains. Much ammonia and nitrous acid are produced by the metabolism of fishes in river water and reservoirs, the decomposition of baits and rotten plants. Ammonia and nitrous acid form nitrates through the action of nitrifying bacteria, and the nitrates cannot be re-decomposed and can only accumulate in water to cause deterioration of water quality. The waterweed can absorb the nitrate, thereby slowing down the accumulation of the nitrate and maintaining the water quality. The aquatic weeds can absorb water, mineral substances and carbon dioxide from water, and can also absorb and treat a plurality of organic matters in the surrounding environment, wherein the organic matters comprise a plurality of toxic substances and pollutants, so that the aquatic weeds can eliminate certain harmful substances and heavy metals in the water.
2. The microbial ecological pool 1 forms a microenvironment with an aerobic-facultative-anaerobic composite structure, realizes nitrification and denitrification through a biological contact purification principle, constructs a strong biological purification system in a water body, largely cultures indigenous microbes in water by providing a mode of suspending nanofiber carriers in all pools, and a large amount of microbes carry out aerobic decomposition on organic pollutants in water under the environment of sufficient dissolved oxygen and flowing water, thereby realizing water body purification. Therefore, the river water and reservoir water have extremely high self-cleaning capability, and can decompose and digest foreign organic pollutants in time, so that the water body is kept in a clean state. The nano fiber carrier is usually formed by fixedly hanging the upper end and the lower end to form a row of hanging curtains, and pollutants in the nano fiber carrier are fully contacted with a biological film growing on the hanging curtains and subjected to biodegradation and assimilation through the stirring and mixing action of an aeration system in the flowing process of water in a pool. Meanwhile, the nanofiber carrier has a large surface area, can absorb, adsorb and intercept dissolved and suspended pollutants in water, provides good growing, attaching or hole-dwelling conditions for the growth and propagation of various microorganisms, and finally forms a thin biological film with a strong purification activity function on the nanofiber carrier, and the nanofiber carrier can excite the activity of microorganisms and promote the degradation and conversion of the pollutants. On one section of the biological membrane, three reaction zones of aerobic, facultative anaerobic and anaerobic are formed from outside to inside. In the aerobic zone, aerobicBacteria convert ammonia nitrogen into nitro nitrogen and convert small molecular organic matters into carbon dioxide and water (inorganic phosphorus is converted into ATP in cells); in the anaerobic zone, the anaerobic bacteria convert nitro nitrogen into nitrogen and oxygen (to decompose the undegradable macromolecular organic matters into degradable micromolecular organic matters). Finally, the pollution groups are decomposed and converted into N of the escaping water body2、CO2And H2O。
3. The sea sand valveless sand filter tank in the traditional process is replaced by a multi-medium filter tank 2 containing zeolite mineralized sintered spheres, volcanic mineralized sintered spheres and medical stone mineralized sintered spheres. The medium in each stage of the multi-stage filter tank can be freely combined according to the requirement. For example, the medium in each stage of the filter tank is a mixture of a large amount of single medium and a small amount of other medium, or 100% of single-kind medium. Nitrogen is one of important pollution factors, ammonia nitrogen not only causes water eutrophication, but also causes water to lack of oxygen, microorganisms are easy to breed in a water supply pipe network due to the existence of ammonia nitrogen in factory water, a biological film is formed to corrode a pipeline, and the oxidized intermediate product, namely nitrite nitrogen, is harmful to health. Therefore, the effective removal of ammonia nitrogen becomes one of the important contents of water treatment. The adoption of zeolite to remove ammonia utilizes the selective exchange capacity of zeolite to cation and the characteristic of regeneration (so that the zeolite has super-strong adsorption property). It is reported in domestic and foreign literature that clinoptilolite pairs NH due to the difference of hydration radii of various cations4+Has strong selective adsorption capacity and has cation exchange sequence of Cs+>Rb+>K+>NH4+>Sr2+＝Ba2+>Ca2+>Na+>Fe3+>Al3+>Mg2+>Li+. From the sequence, the natural clinoptilolite has stronger selective adsorption capacity to ammonium ions, which is mainly NH4+Has an ionic radius of 2.86-and easily enters a pore passage of 4.00-clinoptilolite. Therefore, in the solution in which the above cations coexist, Cs is removed+、Rb+、K+In addition, NH is preferentially adsorbed4+. Laboratory test results: the ammonia nitrogen removal rate after the common sand filtration is 85 percent, and the ammonia nitrogen removal rate after the zeolite is used for treating reaches more than 94 percent. Organic compoundsContaminants are a major class of contaminants in contaminated water sources. The adsorption capacity of the zeolite to organic pollutants mainly depends on the polarity and the size of organic molecules, polar molecules are easier to adsorb than nonpolar molecules, and the chances of being adsorbed into holes are gradually reduced along with the increase of the diameter of the molecules. Containing polar groups such as-OH,>C＝O、-NH2Or containing polarizable groups such as>C＝<,C6H5And organic molecules of the zeolite can have strong adsorption with the surface of the zeolite. Methylene dichloride, trichloromethane, trichloroethane, tetrachloroethane and tribromomethane belong to the easily adsorbed substances of zeolite. The carbon tetrachloride molecules are nonpolar, but the diameter of the carbon tetrachloride molecules is 0.68-0.69 nm, and the carbon tetrachloride molecules can enter zeolite holes. The chloroform precursor humic acid or fulvic acid in natural water is a high-molecular organic acid with an aromatic ring basic structure, but the molecules of the humic acid or fulvic acid are often-COOH,>C＝O、-NH2The strongly polar functional groups may be adsorbed on the outer surface of the zeolite and partially removed. Other common organic pollutants such as phenols, aniline, benzoquinone, amino acids and the like have polarity and moderate molecular diameter, and are expected to be adsorbed by zeolite. The zeolite can make up the defect that sea sand has poor adsorption capacity on large organic micromolecules, basically remove the coloring organic matters in the tap water, and has good removal effects on phenol and aniline (namely, the zeolite is very good for the drainage of pesticides, fertilizers and eucalyptus). The imbalance between the lattice structure characteristics of the zeolite itself and the coordination bonds determines the ability of the zeolite to function as a cation exchanger. The natural zeolite can be completely used as ion exchanger for softening hard water after being modified by salt water. Ca in zeolites by volume effect2 +、Mg2+Aliovalent of divalent ions by Na+After reductive replacement, due to small ions of Na+When the zeolite passes through the internal channels and the window holes of the zeolite, the steric hindrance is small, the zeolite can easily enter the channels and can be diffused into the channels, and the internal diffusion speed is high, so that the zeolite has a larger ion exchange capacity and a water softening function. It can remove turbidity, chroma and heavy metal ions in water simultaneously in the ion exchange process. Thereby solving the problem of karst landform waterThe problems of excessive calcium and magnesium ions caused by quality and excessive heavy metal caused by trace leakage of heavy metal in a tailing pond due to geological influence.
4. The volcanic mineralized sintered ball filter material has the characteristics that: the volcanic filter material has the advantages of inertia, corrosion resistance, strong surface hydrophilicity, roughness, porosity, fast speed and large amount of attached biomembranes, positive charge, contribution to the growth of the biomembranes, good carrier of the biomembranes, no inhibitory effect on fixed microorganism elements, no influence on the activity of microorganisms, natural honeycomb porosity of the volcanic filter material and excellent growth environment of zoogloea. No sharp particles, small resistance to water flow, difficult blockage and uniform water and gas distribution; the surface is rough, the film hanging speed is high, and the microbial film is not easy to fall off during backwashing. Is a high-quality water treatment material capable of filtering and film-forming. The removal rate of phosphorus in the water body can reach more than 90 percent, the phosphorus is easy to suspend and does not run when the density is moderate and the back washing is carried out, thereby saving energy and reducing consumption. No sharp particles, small resistance to water flow, difficult blockage and uniform water and gas distribution; the microbial film is not easy to fall off during back flushing. Volcanic rock can make ions in water active (mainly increasing the content of oxygen ions) and slightly release a-rays and infrared rays, and trace elements released by volcanic rock, which are beneficial to organisms including human beings, can promote the metabolism of animal cells and carry harmful halides out of the body to clean the dirt in the cells. The volcanic mineralized sintered ball filter material has the characteristics of small porosity, right average internal and external pores, small resistance to water, and low required filter material amount compared with similar filter materials, and can also achieve the expected filtering target. The biological filter material has strong hydrophilicity, a large amount of attached biological membranes and high speed, is used as a biological membrane carrier, is harmless to fixed microorganisms, has no inhibitory effect, and does not influence the activity of the microorganisms proved by practice. The specific surface area is large, the aperture ratio is high, the inertia is realized, the film contact and growth are facilitated, more microbial biomass is kept, and the mass transfer process of oxygen, nutrient substances and waste generated by metabolism in the microbial metabolism process is facilitated, so that the removal of organic matters in the water body is enhanced, and the turbidity and the peculiar smell of the water body are effectively solved. The shape of the filter material and the flow state of water, because the volcanic biological filter material is non-sharp granular and the aperture is mostly larger than that of ceramsite, the filter material has small resistance to water flow when in use, and saves energy consumption.
5. The function of the medical stone mineralized sintered ball is as follows: the medical stone has obvious adsorption performance on various heavy metal ions, bacteria, nitrite, phenol, water vapor and the like, and kaolin, montmorillonite, chlorite and biotite in the medical stone form clay minerals with a layered structure through corrosion and weathering. In the layered structure of these clay minerals, tetrahedra and octahedra are alternately arranged, and Al in the crystal lattice3+In place of Si4+The excessive negative charges are generated, additional cations are needed between layers to balance the negative charges, the combination of the cations and crystal lattices is relaxed, and ions in water can generate ion exchange effect, which is expressed as dissolution and adsorption performance. The adsorption of Maifanitum is characterized by porous and spongy structure, large specific surface area, and high polarity of molecules such as C02、NH4+The medical stone has strong adsorption capacity and biological implantation property, can adsorb ammonia, hydrogen sulfide, organic chlorine, cyanide, fusel oil and other substances harmful to animal health, thereby solving the pesticide residue in water, and has Sio as main chemical component2Can be formed of [ Si04]4-Based on a spatial network of the bonds between the top oxygen of a tetrahedron and the adjacent tetrahedron, and K+、Na+、Ca2 +、Mg2+Through ionic bond combination, when the medical stone is in the water medium environment, partial ionization is generated, and a large amount of active groups [ -SiO ] are arranged on the other side surface of the structure]-Can capture heavy metal ions (particularly the adsorption capacity of cadmium, arsenic, zinc and manganese is most obvious) in water, and can quickly adsorb microorganisms to form a biological membrane so as to achieve the effects of decomposing organic matters and reducing ammonia nitrogen.
6. The water molecule cutter 4 mainly functions as follows: has strong sterilization function, and can reduce BOD and COD of the water body under the direct action of the magnetic field, reduce the energy and C nutrient substances of heterotrophic organisms, cause the death speed of heterotrophic bacteria of the water body to be higher than the proliferation speed, and then cause the phenomenon of negative growth. Magnetic forces act directly on water and enzymes within the bacterial cell, inactivating or inactivating the enzymes. While the BOD value decreasesThe low is the reflection of the reduction of the total number of bacteria, on one hand, under the direct action of an external magnetic field, BOD is reduced along with the reduction of COD index, on the other hand, under the action of the external magnetic field, functional microorganisms (mainly bacteria) in a water body are influenced, a part of bacteria have strong adaptability, life metabolic activity is not interfered, or although the functional microorganisms are interfered, the functional microorganisms can be recovered to a normal state after a certain time, the part of bacteria survive with stronger adaptability, and most of the bacteria are subjected to the action of an external magnetic field, and the phenomenon of death due to the incapability of adaption is caused by the change of physicochemical properties (such as conductivity, surface tension and the like) of water inside and outside the body and the inactivation and inactivation of enzyme, so that the reduction of BOD index is caused by the rapid reduction of the number of the functional bacteria, and the reduction of BOD index after the magnetic treatment is considered. After water passes through a strong magnetic field, the macromolecule group (H)2O) n water is divided into two molecules (H) by magnetic field2O)2Or a single molecule H2O; after magnetization, the hydrogen-oxygen bond angle of water molecules is reduced from 104.5 degrees to about 103 degrees, the direction of the magnetic distance between atoms is changed, the value is increased, and the property of the fluid is changed. The magnetic energy of the magnetic field is utilized to activate water molecules, so that large water molecular groups are converted into small molecules, and the water is magnetized (small molecules) running water. The small molecular water has the strongest activity, so that the self-repairing capability of the water quality is stronger, in addition, the mineral substances required by people are easier to absorb, in addition, the polarization effect and the hysteresis effect are stronger, the excessive calcium and magnesium ions in the water body can be effectively prevented from being deposited, and hard water is changed into soft water. Polarization: the polarization of the magnetic field causes a change in the crystalline composition of the salt. The polarity of the micro-particles is enhanced, the cohesive force is weakened, the original longer associated molecular chain in the water is cut off into the shorter associated molecular chain and the deformation of the charged ions, the electrostatic attraction among the ions is destroyed, and the crystallization condition is changed. Dispersed stable small crystals are formed. Hysteresis effect: the magnetic field causes a hysteresis effect of a magnetic couple of salt molecules or ions in water, thereby changing the solubility of the salt in water and eliminating the affinity (crystallinity) between the salt molecules to prevent crystallization of large crystals.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention, and all technical solutions that fall under the spirit of the present invention fall within the scope of the present invention. It should be noted that several modifications and refinements without departing from the inventive concept will occur to those skilled in the art, and such modifications and refinements should also be considered as within the scope of the present invention.
