Description

An integrated sewage treatment equipment

technical field

The utility model relates to the technical field of rural domestic sewage treatment, in particular to an integrated sewage treatment equipment.

Background technique

Rural domestic sewage treatment refers to the removal and degradation of harmful substances and environmental pollution components in water for harmless treatment. The treated reclaimed water is used for agricultural irrigation to relieve the tension of agricultural water use.

At present, rural domestic sewage has the following characteristics in terms of treatment and operation:

(1) The components of pollutants contained in sewage are becoming more and more complex, and the concentration of various pollutants fluctuates greatly.

(2) The population distribution is scattered, the water consumption of a single household is low, and the scale of sewage treatment is small, resulting in high construction and operation costs.

(3) The drainage pipe network system is not perfect, the population is scattered, and the sewage is produced in scattered places, making it difficult to collect.

(4) There is a serious lack of maintenance and management technicians and operation management experience, and it often happens that the sewage treatment facilities built in rural areas cannot operate normally and cannot fully exert their effects.

It can be seen from the above that rural domestic sewage has the characteristics of wide distribution, scattered generation locations, large changes in water quality and quantity, and difficulty in collection.

The integrated treatment equipment for rural domestic sewage mainly includes integrated biological purification tanks, membrane bioreactors, small biological filters, combined ecosystems, etc. The investment and operation cost of the integrated biological purification tank is expensive, the per capita investment cost is about 10,000 yuan, and the construction of a 5-person (1m ³ /d) purification tank needs 70,000 yuan, and the technology is complicated, requiring professionals to operate and manage it. It is popularized in China It is more difficult. A single membrane bioreactor (MBR) process is not effective in removing nitrogen and phosphorus, and often cannot meet the requirements for recycling. It needs to be combined with other processes to achieve better treatment effects. In addition, the problems of energy consumption and membrane fouling are Key factors restricting the promotion of MBR, in which aeration energy consumption plays a leading role in the operation energy consumption, accounting for more than 80% of the entire operation energy consumption. In addition, membrane filtration and backwashing also require energy consumption, resulting in increased power consumption and operating costs; Moreover, the membrane is easily polluted, which intensifies the frequency of membrane cleaning and renewal, and greatly affects the treatment effect and service life of membrane modules, thus limiting the promotion of MBR in projects. Small-scale biofilters need to lay sewage pipe networks, which increases investment costs, and most of the systems are exposed to the outside environment. They are greatly affected by the climate, and can hardly operate normally in winter. The process is complicated, and the cost of infrastructure and operation management is high. Popularization and application in villages and towns with backward technology. The combined ecological system is a new process suitable for the low-consumption ecological treatment of decentralized sewage. It mainly includes regulating tanks, ecological tanks, sedimentation tanks, filtration and disinfection devices. Its modular design can be built according to specific conditions, reducing the area occupied. However, the structure of the ecological bucket is single, the materials used are expensive, and the flexibility of the system is insufficient, and the combined system mostly focuses on the research on the structure of the ecological bucket and the type of functional plants, while ignoring the coupling and optimization of the functions of the entire system. Therefore, it is necessary to achieve large-scale promotion and application , further research is still needed.

Example 1

In this embodiment, the equipment shown in Figure 1 is used for rural sewage treatment, and the domestic sewage after passing through the fine grid is used as the influent. The influent water volume is 0.042m ³ /h, and the influent water quality is as follows: COD is 86.57-350.70 mg/L, ammonia nitrogen is 14.32~53.84mg/L, TN is 20.52~58.32mg/L, TP is 1.76~7.18mg/L, SS≤220mg/L, pH is 6~9.

In this embodiment, the first valve 104 is opened, so that about 30% of the influent sewage enters the anoxic zone 100 , and about 70% of the influent sewage enters the anaerobic zone 200 .

Firstly, the domestic sewage enters the anoxic zone 100 from the water inlet pipe 101 of the anoxic zone for denitrification reaction, and the dissolved oxygen is controlled between 0.2-0.5 mg/L. About 70% of the sewage influent enters the anaerobic tank (200) through the anoxic zone bypass pipe 103 and the bypass pipe outlet 201.

Further, the effluent from the anoxic zone 100 enters the anaerobic zone 200 through the water inlet pipe 202 of the anaerobic zone. The dissolved oxygen content in the anaerobic zone 200 is generally controlled below 0.2mg/L. In the dephosphorization process, it mainly plays the role of biological phosphorus removal. Biological phosphorus removal consists of two processes of phosphorus absorption and phosphorus release. When phosphorus accumulation bacteria release phosphorus anaerobically, soluble and rapidly biodegradable organic matter is stored in the bacteria to degrade COD, and then accumulate phosphorus in an aerobic environment. Bacteria overabsorb phosphorus. The anaerobic zone 200 uses a combination of fillers, specifically: polypropylene porous rotating suspension balls, made of polypropylene material, with a diameter of 100 mm, 3-5 Banhor high-efficiency biological carriers and a piece of about 20-30 mm in length and a width of 100 mm in the suspension ball Oval-shaped reddish-brown common volcanic rocks of about 50-60mm in order to maintain sufficient biomass in the upper area.

Further, the effluent water from the anaerobic zone 200 enters the aerobic zone 300 through the water inlet pipe 301 of the aerobic zone. The aerobic zone 300 adopts MBBR process, and the filler is Banhor high-efficiency biological carrier produced by Banghao Company (the commercial product is Banhor high-efficiency biological carrier), and the filler dosage is 5kg/m ³ . This process is to add suspended filler in the bioreactor of the activated sludge process, which combines the advantages of the activated sludge process and the biofilm process, and avoids the shortcomings of the two processes at the same time, and plays the role of simultaneous biological denitrification and phosphorus removal; good The dissolved oxygen content in the oxygen zone 300 is generally controlled above 2.0 mg/L.

Further, an aerobic zone air intake pipe 304 is provided in the aerobic zone 300, and an electromagnetic blower (power 39W) enters the aerobic zone air intake pipeline 304 through the aerobic zone air inlet 302, and is delivered to the aerobic zone 300 In the microporous aeration disc 305 at the bottom, high-efficiency aeration is realized. The air inlet pipe 304 in the aerobic zone is fixedly connected to the microporous aeration pan 305 through the aeration pan fixing connector 307 .

Further, the effluent from the aerobic zone 300 flows into the bottom of the sedimentation zone 400 through the sedimentation zone inlet pipe 406 for solid-liquid separation. In the precipitation zone 400, the electromagnetic blower (power 39W) provides power for the reflux of the mixed solution in the mixed solution riser 408 by the precipitation zone air inlet 403 through the precipitation zone air lift pipe 407, and the electromagnetic blower provides power to the aerobic zone 300 simultaneously. Air, a blower is used in this embodiment; after the mixed solution at the bottom of the sedimentation zone 400 passes through the mixed solution riser 408, a part of it flows back into the anoxic tank 100 through the mixed solution return pipe 401 and the anoxic zone return pipe 102 to promote denitrification Reaction; the other part is returned to the aerobic zone 300 through the mixed liquid return pipe 401 and the aerobic zone return pipe 303 to supplement the amount of active microorganisms.

Further, the water outlet in the sedimentation zone 400 enters the clean water zone 500 by the clean water zone water inlet 404 through the clean water zone water inlet pipe 405, and the water in the clean water zone 500 is discharged by the clean water zone water outlet 502 through the clean water zone outlet pipe 501.

The operation time of the equipment is 1d, and the water quality of the water outlet 502 of the clear water area is measured by taking samples at the whole point. The sewage treatment effect of this embodiment is:

The COD of the device effluent is 22.57-58.70 mg/L, with an average value of 47.79 mg/L, and the COD removal rate is about 75.32%; the device effluent ammonia nitrogen is 0.34-7.86 mg/L, with an average value of 4.14 mg/L; the device effluent TN is 8.96~19.92mg/L, with an average value of 15.75mg/L; the TP of the device effluent was 0.4~2.67mg/L, with an average value of 1.71mg/L.

Example 2

The water quality and quantity of domestic sewage in rural areas vary greatly, and the peak periods of water use are concentrated in three time periods: 7:00-8:00, 12:00-13:00, and 17:00-18:00. In order to better simulate the current situation of rural domestic sewage discharge, this example adjusts the water intake in the above time period to twice that of Example 1 to explore the impact of instantaneous water impact on the performance of the test device. Other water intake steps and control steps are basically the same as in Example 1. The quality of influent water is as follows: COD is 298.20~389.47mg/L, ammonia nitrogen is 0.14~57.31mg/L, TN is 46.01~55.03mg/L, TP is 4.33~7.02mg/L, SS≤220mg/L, pH is 6~9.

The operation time of the equipment is 1d, and the water quality of the water outlet 502 of the clear water area is measured by taking samples at the whole point. The sewage treatment effect of this embodiment is:

The COD of the device effluent is 50.14～57.31mg/L, with an average value of 54.23mg/L; the device effluent NH ₃ -N is 0.36～0.96mg/L, with an average value of 0.63mg/L; the device effluent TN is 14.02～17.04mg/L L, the average value is 14.75mg/L; the TP of the device effluent is 1.02-2.36mg/L, the average value is 1.62mg/L.

According to the water discharge data of Example 2 and Example 1 of the present application, it can be seen that the device of the present invention can withstand the impact of instantaneous water volume.

Comparative example 1

The difference between this comparative example and Example 1 is that the first valve 104 is closed, the anoxic zone bypass pipe 103 and the bypass pipe outlet 201 are not used, and all the sewage enters the hypoxic zone. The influent water quality of this example is as follows: COD is 130.0-350.70 mg/L, NH ₃ -N is 15.05-53.84 mg/L, TN is 22.52-55.18 mg/L, and TP is 1.53-7.18 mg/L.

The operation time of the equipment is 3-7 days, and the water quality of the water outlet 502 of the clear water area is measured by sampling at the whole point. The sewage treatment effect of this comparative example: the COD of the effluent of the device is 33.1-105.4mg/L, and the average value is 64.98mg/L; the effluent of the device is NH ₃ -N is 1.50-7.26mg/L, with an average of 5.16mg/L; TN of the effluent from the device is 14.30-24.68mg/L, with an average of 18.85mg/L; TP of the effluent from the device is 1.32-3.73mg/L, with an average of The value is 2.08mg/L.
