Description
Technical Field
The utility model relates to a sewage treatment technical field especially relates to an improved generation coagulating sedimentation dephosphorization treatment facility.
Background
In sewage treatment, nitrogen and phosphorus removal are issues which need to be considered. For inducing water eutrophication, the action of phosphorus is far greater than that of nitrogen, so that the control of the concentration of phosphorus is very important. At present, the phosphorus removal technology adopted by municipal sewage treatment plants mainly comprises two types of biological phosphorus removal and chemical phosphorus removal. Biological phosphorus removal is completed by excessive absorption of soluble phosphate in a polluted water body by microorganisms under an aerobic condition. Chemical phosphorus removal is to add chemical agents into a water body and achieve the aim of phosphorus removal by forming precipitates through the reaction of the chemical agents and phosphate in the water body. Domestic and foreign experience shows that the adopted biological phosphorus removal method has very strict requirements on conditions and is easily influenced by the fluctuation of the quality and quantity of inlet water, and the phosphorus removal amount is generally BOD53.5-4.5% of the removal amount, and the phosphorus content in the effluent is hardly lower than 1.0 mg/L. In addition, because of the age difference between nitrifying bacteria and phosphorus accumulating bacteria, nitrogen and phosphorus removal are conflicting targets for biological treatment process. Therefore, the better treatment means is to meet the denitrification target preferentially, and then to chemically remove the phosphorus by the coagulation and precipitation process, so that the effluent meets the discharge standard of the phosphorus pollutants.
The existing coagulating sedimentation dephosphorization process is generally provided with a mixing zone, a flocculation zone and a sedimentation zone. Lime, PAC or PFS are added into the mixing zone as a phosphorus removal agent, and the agent and the sewage are fully mixed and reacted through rapid stirring to be condensed into micro-floccules; PAM is added into the flocculation area as a flocculating agent, flocculation is enhanced through slow stirring, and small flocs are converted into larger flocs to form chemical sludge; the mud-water separation is completed in the settling zone through measures such as gravity settling or mechanical cyclone and the like, so that the concentration of phosphorus in water is reduced, and the discharge standard is reached. In practical application, for the sewage treatment with small water amount, the process has the following defects:
since the chemical reaction is often accompanied by side reaction, and the phosphorus removal agent is required to be excessively added to achieve the expected effect (according to volume 5 of handbook of Water supply and drainage Manual, the concentration of P in the effluent is required to be below 0.5mg/L, the molar ratio of metal ions added in the post-precipitation and synchronous precipitation chemical phosphorus removal process to the total phosphorus in the inlet water is required to be 2, and the theoretical value is less than 1), on one hand, a large amount of consumption of the agent is caused, on the other hand, a large amount of chemical sludge is generated, and therefore, the operation cost of the agent addition and sludge disposal is high.
The mechanical stirring of the coagulation area and the flocculation area needs long-term electricity consumption, and the electricity cost is high for projects with less water treatment amount.
Although the high molecular polymer-Polyacrylamide (PAM) has better coagulation aiding effect, the PAM needs to be added after being dissolved, the dissolution time is long, and the PAM is easy to lose efficacy after being dissolved.
The sedimentation tank suitable for small-volume sewage treatment is generally a vertical flow type sedimentation tank and an inclined plate type/inclined tube type sedimentation tank, the height of the vertical flow type sedimentation tank is large, the construction is difficult, the impact load resistance of the inclined plate type/inclined tube type sedimentation tank is poor, the mud-water separation effect is poor when the water quality fluctuates, the SS content of the effluent is often overproof, and subsequent filtration measures are required.
At present, a coagulating sedimentation dephosphorization treatment device with high treatment efficiency is lacked.
