Example 1

Referring to fig. 1, the present embodiment provides a wastewater treatment system, which includes a plurality of reaction tanks 1 connected in series, and an aeration system for performing aeration treatment on the reaction tanks 1, wherein reaction fillers are disposed in the reaction tanks 1, and the wastewater treatment system further includes a filler mechanism 11 for filling the reaction fillers, the filler mechanism 11 is disposed in the reaction tanks 1 so as to be convenient for taking out the filler mechanism 11, and a gap exists between the filler mechanism 11 and the reaction tanks 1. The filling mechanism 11 comprises a plurality of filling baskets 111, and the filling baskets 111 are distributed in the reaction tank 1 at intervals in an array manner; the filler mechanism 11 is adopted to fill the filler, and the gap between the filler mechanism 11 and the reaction tank 1 and the gap between the fillers are utilized to treat the wastewater, so that the fillers are convenient to replace and clean, and the possibility of blockage of the aeration mechanism is reduced.

Because of the problems of self reaction of an iron-carbon system, calcium sulfate precipitation brought in at the front end and the like, the holes of the aeration pipe are easily blocked, the back flushing effect by water pressure is gradually reduced, and the aeration effect is an important factor influencing the pretreatment of the wastewater; in order to further reduce the possibility of blockage of the aeration pipes, the present embodiment adopts an independent design of the aeration pipes of each filler basket 111, and the specific implementation manner is as follows: the aeration system comprises a plurality of aeration branch pipes 2, and the aeration branch pipes 2 are arranged corresponding to the filler baskets 111 one by one.

After the filler is pretreated and operated for a period of time in the wastewater, sludge is wrapped around the filler, gaps among the filler are almost not formed after the operation is long, the processing capacity is greatly reduced, the filler basket 111 needs to be cleaned, and only the sludge on the surface of the filler can be cleaned when the sludge is manually cleaned and cleared, and the sludge in the gaps among the filler is difficult to clean or cannot be cleaned, so that the value of the filler is not effectively utilized by a large amount of filler; by adopting the design, the utilization rate of the filler is effectively improved, and the wastewater pretreatment cost is reduced; after long-term use, the packing basket 111 needs to be replaced, and the packing basket 111 needs to be lifted out of and into the reaction tank 1.

The cleaned sludge needs to be discharged in time, so that the normal operation of an aeration system is prevented from being influenced, and the sludge formed by mixing pollution and water has fluidity; by adopting the design, the labor intensity of workers in cleaning work when the iron carbon is adhered to the sludge in daily maintenance is effectively reduced, and the occupational health hazard risk is reduced.

If the reaction tank 1 is added with hydrogen peroxide for reaction, the reaction tank 1 has small capacity, short retention time of wastewater, insufficient catalytic reaction and influence on the degradation effect of pollution factors for wastewater treatment, and if excessive hydrogen peroxide is added for reaction to solve the problems, a large amount of sludge is attached to the surface of the filler, and the reaction effect of the filler is influenced, namely, the pollution accumulation amount is large and fast. The cleaning and the adding of the filler are required as long as the operation is performed, so that the labor and the financial resources are consumed, and the cost of wastewater pretreatment is increased; therefore, in the embodiment, the device further comprises a dosing tank 3 for collecting the wastewater treated from the reaction tank 1, and the dosing tank 3 is specially used for adding hydrogen peroxide for reaction and is communicated with the last stage reaction tank 1; by adopting the design, the frequency of sludge cleaning is effectively reduced (1 month/time is reduced to 3 months/time for original cleaning), and the amount of added iron and carbon is reduced (10 tons/1 month is reduced to 10 tons/3 months for original cleaning).

Example 2

The present embodiment includes all the contents of embodiment 1, except that, as shown in fig. 2, fig. 3 and fig. 4, the stuffing basket 111 includes support legs 1111 and a basket body 1112, the basket body 1112 is a box body with an open top end, a sieve plate 1113 is arranged in the basket body 1112 to divide the inner cavity of the basket body 1112 into an air bin 1114 and a stuffing bin 1115, the stuffing bin 1115 is located right above the air bin 1114, and the air bin 1114 is communicated with the aeration branch pipe 2; one end of the supporting leg 1111 is connected to the basket body 1112, and the other end of the supporting leg 1111 is supported on the bottom of the reaction chamber 1.

Because the aeration pipe is extremely easy to block, and the aeration effect is the important factor that influences waste water pretreatment, in order to guarantee in time that after some aeration branch pipes 2 take place to block up, reaction tank 1 can normally work anyhow, keeps good treatment effeciency, still includes pressure air blast pipe 1118, and aeration branch pipe 2 passes through pressure air blast pipe 1118 and communicates gas storehouse 1114, and the pressure air blast pipe 1118 of adjacent filler basket 111 communicates each other.

In actual use, the utilization rate of the filler on the periphery of the filler basket 111 is obviously higher than that of the internal filler, the replacement is to replace the whole filler frequently, so that the central filler is discarded for full use, and unnecessary waste is caused, in order to fully utilize the filler, in the embodiment, a plurality of filler annular grooves 1117 are sequentially sleeved from outside to inside in the filler bin 1115, the adjacent annular grooves 1117 are detachably connected, when the filler is replaced, the mutually sleeved filler annular grooves 1117 can be independently replaced, the replacement frequency of the periphery is obviously higher than that of the inside, by adopting the design, the utilization rate of the filler is improved, and the clearance of the filler is convenient to clean, it needs to be explained that the annular groove 1117 of the outermost layer of the filler is matched with the shape of the filler bin 1115 and can be polygonal, circular or elliptical, and the annular groove 1117 of the inner layer of the filler can not be limited by the design, the shape of the annular packing groove 1117 may be any shape, and the annular packing groove 1117 used in this embodiment is rectangular, as shown in fig. 5, while in other embodiments, it may be square, round or oval, as shown in fig. 6, and the above list is only for the purpose of illustration, and is not intended to limit the embodiments of the present invention.

Adopt the utility model discloses handle 3(4) -nitro o-xylene's waste water, pollution factor clearance COD promotes 72.59% from 37.23%, and aniline promotes 86.12% from 31.05%, and nitro thing promotes 95.07 from 47.56%.

The sludge cleaning frequency is reduced to 3 months/time from 1 month/time of the original cleaning, the number of operators is reduced to 3 persons from 6 persons, and the cleaning time is reduced to 2 days from 4 days. The labor cost is reduced by 8 times 6 times 300 yuan/day 4 times 3 times 300 yuan/day 2 84800 yuan, namely 8.48 ten thousand yuan.

The addition amount of the filler is reduced from the original 10 tons/month to 10 tons/3 months, the addition amount of the iron and carbon is reduced by 80 tons per year, and the iron and carbon is saved by 0.7 yuan by 80 yuan by 56 ten thousand yuan and the labor cost for adding the iron and carbon is reduced by 80 yuan by 48 yuan by 3840 yuan according to the price of 7000 yuan per ton.

Because the removal rate of the pollution factors is improved, the water content of the diluted wastewater is reduced to 0.3 time of the original water content when the wastewater enters the next step (namely a biochemical system), and the treated water is reduced by 0.3 x 12t/h 24h x 50 yuan/t x 300 days

And/10000 is 129.6 ten thousand yuan.

In conclusion, as the efficiency of the wastewater treatment system is improved, the pollution factors of the wastewater after the pretreatment process are reduced, the biochemical system can realize the production in increased quantity, partially solve the problem of the limitation of the wastewater on the production energy of the production line, realize the production in increased load of the main production line and improve the yield, thereby creating more economic benefits.
