The embodiment provides an algae removal device for high-turbidity high-algae micro-polluted raw water, which is implemented by performing pre-oxidation enhanced coagulation and performing rear-end ultraviolet/chlorination synergistic disinfection, and the device is based on a process of water inlet + pre-oxidation (potassium permanganate + sodium hypochlorite) + coagulation (polyaluminium chloride + lime) + precipitation + sand filtration + disinfection (sodium hypochlorite + high-strength ultraviolet) + water outlet, and by performing synergistic pre-oxidation, the respective advantages of potassium permanganate and sodium hypochlorite are utilized to inactivate algae cells, change the extracellular polymer potential of the algae cells and promote effective contact of the algae cells and a coagulant; through the synergistic coagulation of aluminum salt and calcium salt, the size and compactness of flocs are optimized, the pH value of a water body is effectively adjusted, the flocculation precipitation effect is enhanced, and the algae removal efficiency is improved; the synergistic disinfection of sodium hypochlorite and a high-strength ultraviolet lamp can effectively control the contents of algal toxins, disinfection byproducts and pathogenic microorganisms, and ensure the safety of water supply.

In this embodiment, the apparatus further comprises a regulating reservoir (not shown in the figure), wherein the water inlet end of the regulating reservoir is connected with the raw water, and the water outlet end of the regulating reservoir is connected with the pre-oxidation unit.
In this embodiment, the sedimentation tank 4 is a sloped tube sedimentation tank.
In this embodiment, the sedimentation tank 4 is a 65 ° inclined tube sedimentation tank.
In this embodiment, the filter 5 is a V-shaped sand filter, and the filter material in the sand filter has a particle size of 0.8-1.2 mm.
The method for removing the algae in the water body through the device comprises the following steps:
(1) raw water is lifted by a pressure pump and enters a regulating reservoir; the concentration of the simulated raw water algae is 3.1 multiplied by 108～9.2×108And (2) per liter. After raw water enters the pre-oxidation unit 1 through the regulating reservoir, firstly potassium permanganate is added into the pre-oxidation unit 1, then sodium hypochlorite is added, and pre-oxidation is carried out through the synergistic effect of the potassium permanganate and the sodium hypochlorite so as to inactivate algae cells, maintain the integrity of the algae cells, avoid the release of algae toxins by the algae cells, and simultaneously effectively control the content of halogenated disinfection byproducts and residual manganese. The action principle of the pre-oxidation is as follows: the density of algae cells is close to the density of water, the direct coagulation sedimentation effect is poor, oxygen is generated due to photosynthesis after sedimentation, floc can also float upwards, and the algae cells are pre-oxidized by using an oxidant, so that on one hand, the algae and microorganisms in water are remarkably inhibited, the algae is inactivated in motion, and the generation of photosynthesis gas in the sedimentation process is avoided; on the other hand, under the action of the oxidant, the algae and the microbial cells can secrete biochemical polymers, and the extracellular organic matters of the algae play a role similar to anionic or nonionic polyelectrolytes, so that the coagulation is enhanced, and the algae removal is promoted. However, the potassium permanganate is independently adopted for pre-oxidation, so that excessive manganese addition can be caused, the water color is darker, and the effluent turbidity and manganese ions exceed the standard; chlorine preoxidation is independently adopted, and excessive chlorine adding may exist, so that organic matters in raw water generate carcinogenic teratogenic disinfection byproducts such as trihalomethane and the like under the chlorination action. Based on the reasons, the embodiment adopts a mode of jointly adding potassium permanganate and sodium hypochlorite, combines the advantages of the two types of oxidants, and effectively avoids the problem caused by excessive addition of a single oxidant, so that the pre-oxidation can be realized as far as possible, the algae cells can be inactivated, the integrity of the algae cells can be maintained, the algae cells are prevented from releasing algae toxins, and halogenated disinfection byproducts and residual manganese content are reduced.
(2) Raw water enters a coagulation tank 2 and a flocculation tank 3 in sequence after being pre-oxidized, polyaluminium chloride (PAC) is added into the coagulation tank 2, lime (CaO) is added into the flocculation tank 3, the molar ratio of the polyaluminium chloride to potassium permanganate is controlled to be 3: 1-4: 1, the molar ratio of the lime to the potassium permanganate is 0.5: 1-0.7: 1, coagulation is carried out through the synergistic effect of the polyaluminium chloride and the lime, so that the coagulation efficiency is improved, the grain size and the compactness of flocs are improved, and meanwhile, double electric layers are compressed, so that the flocs are destabilized and the coagulating sedimentation effect is enhanced. The principle of the cooperative coagulant feeding is as follows: when the algae content is high, if only a proper amount of aluminum salt is added, the density of flocs is insufficient, the settleability is slightly poor, and the algae removal effect is poor; if the adding amount of aluminum salt is increased, although the algae removal effect is improved, excessive aluminum salt hydrolysate not only causes the pH value of a water body to be greatly reduced, influences the destabilization of particles and is not beneficial to further precipitation, but also causes the excessive aluminum salt in effluent to cause the water drinking safety risk (such as the risk of causing senile dementia). When the aluminum salt is properly added, lime is cooperatively added, so that on one hand, the density of floc generated by lime flocculation is higher, the settlement of aluminum salt floc can be promoted, and the algae removal is strengthened; meanwhile, the alkalinity can be increased, the pH can be adjusted back, and the effluent quality can be guaranteed. Therefore, by the aluminum and calcium salt synergistic coagulation method, the particle size and compactness of the flocs can be effectively improved, the double electric layers are compressed, the flocs are destabilized, the coagulation effect is enhanced, and the subsequent precipitation and algae removal are promoted.
(3) The mixed liquid after preoxidation and coagulation enters a sedimentation tank 4 (a 65-degree inclined tube sedimentation tank) for sedimentation, most algae and organic matters are removed by sedimentation in a floc form, the turbidity of the water body is greatly reduced, and a small amount of algae, floc particles with smaller particle size and suspended matters still remain in the effluent.
(4) The precipitated effluent enters a filter 5 (V-shaped sand filter), and the filtering speed is controlled to be 47-62m/h so as to further remove residual algae, fine suspended matters and floc particles generated by coagulation, so that the turbidity of the effluent and the algae reach extremely low levels.
(5) And (3) enabling the water discharged from the filter tank to enter a clean water tank 6, opening a high-strength ultraviolet lamp in front of the clean water tank to degrade and remove disinfection byproducts and algal toxins possibly generated by a front-end pre-oxidation unit, and adding sodium hypochlorite behind the clean water tank to further control the content of the algal toxins and pathogenic microorganisms. Terminal disinfection and byproduct control are carried out through the synergistic effect of high-strength ultraviolet light and sodium hypochlorite, and water supply safety is guaranteed. In the unit, the high-strength ultraviolet light has the effect that when the chlorination of the front-end pre-oxidation unit is excessive, organic matters in algae cells are released possibly to cause the problems of increase of chlorination disinfection byproducts and algal toxins in effluent and the like, and in order to control and avoid the problems caused by pre-oxidation, the high-strength ultraviolet light is utilized at the tail end to degrade and remove the disinfection byproducts and the algal toxins through high-density photon flux, so that the content of the algal toxins in the effluent is controlled to be below 0.1 ug/L. The effect of adding sodium hypochlorite again at the tail end is that when the chlorination of the front-end pre-oxidation unit is insufficient, the residual chlorine is added again at the effluent, the concentration of the residual chlorine in the effluent is ensured to be about 0.15mg/L, the contents of pathogenic microorganisms and escherichia coli in the effluent are controlled, and the effluent safety is ensured.
Through the process, the content of algae in the effluent can be controlled to be 0.5-1.0 multiplied by 104The removal rate reaches 89-98%; turbidity below 1 NTU; the residual chlorine is 0.1-0.2 mg/L; the total manganese is within 0.2 mg/L.
In this example, in step (1), the pre-oxidation time of the pre-oxidation unit was 50 min.
In the embodiment, in the step (3), the hydraulic retention time of the sedimentation tank is 38-46 min.
In this embodiment, in step (3), the high-intensity ultraviolet photon flux is controlled to be 3.13 × 10-6einstein/(cm2S) above, the adding amount of sodium hypochlorite is controlled to be 0.4-0.6 mg/L.

2) Good coagulating sedimentation effect and high algae removal efficiency
After algae are inactivated by pre-oxidation, two traditional coagulants of aluminum salt and calcium salt are cooperatively added, so that excessive addition of single aluminum salt is avoided, and the excessive risk of aluminum effluent is avoided; on the other hand, the calcium salt is added in a synergistic manner, so that the flocculation efficiency of single aluminum salt can be improved by utilizing the characteristic that calcium salt floc particles are larger, and meanwhile, the pH value reduced by aluminum salt hydrolysis can be effectively adjusted back by calcium salt hydrolysis, so that the pH value of effluent water is ensured.
3) The tail end photodissociation/disinfection capability is strong, and the effluent quality is guaranteed
