Description

Sugar industry effluent treatment plant

Technical Field

The utility model relates to an environmental protection technology field particularly, relates to a sugaring industrial wastewater treatment device.

Background

Water shortage and serious water body environmental pollution in China require the total discharge amount of pollutants of sugar-making wastewater and the standard discharge of water pollution indexes. The prior sugar industry wastewater treatment method mainly adopts aerobic biochemical treatment, such as activated sludge and a biofilm method. However, the management is not good in the production process, sugar and sugar are easy to carry, the concentration of COD pollutants in the waste water after sugar is carried out is generally more than 1500mg/L, and is often 2-3 times higher than the COD value of the inlet water designed by an aerobic biochemical system, and organic matters cannot be completely digested and degraded. Most enterprises mix and dilute high-concentration sugar-making wastewater and clear water into low concentration, and then adopt aerobic biochemical treatment, so that organic matters can be digested and degraded, and the wastewater reaches the standard and is discharged; but the treatment process needs a large amount of clear water and a large amount of treatment devices, so that the energy consumption and the operation cost are increased, and the treatment capacity is also reduced.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a sugaring industry effluent treatment plant to the above-mentioned defect among the prior art.

In order to realize the above purpose, the utility model provides a sugar industry effluent treatment plant, including oil interceptor, cooling tower, acidizing jar, equalizing basin, TLP anaerobic reactor, settling cask, neutralization pond, oxidation ditch and the sedimentation tank that communicates in proper order, the other charge device that is provided with of equalizing basin is equipped with the elevator pump between equalizing basin and the TLP anaerobic reactor, the gas outlet of oxidation ditch in-connection blast aeration machine.

The sugar industry wastewater treatment device also comprises a sludge concentration tank and a filter press, wherein a sludge port of the sedimentation tank is connected with an inlet of the sludge concentration tank, and an outlet of the sludge concentration tank is connected with an inlet of the filter press. The sludge concentration tank and the filter press are used for removing the moisture of the sludge, so that the volume of the sludge is reduced, and the subsequent treatment cost of the sludge is reduced.

Return pipes are communicated between the TLP anaerobic reactor and the settling tank and between the oxidation ditch and the sedimentation tank.

Compared with the prior art, the utility model has the advantages that:

the utility model discloses a system sugar industrial wastewater treatment device is rationally distributed, uses the device to carry out system sugar industrial wastewater treatment, handles high concentration system sugar industrial wastewater through oil interceptor, cooling tower, acidizing jar, equalizing basin, TLP anaerobic reactor and settling cask earlier in proper order, makes the concentration of high concentration system sugar industrial wastewater reduce, then mixes the back with low concentration system sugar industrial wastewater again, and the waste water that mixes the gained adopts good oxygen biochemical treatment. After being subjected to acidification hydrolysis and anaerobic digestion, the high-concentration sugar-making industrial wastewater is mixed with the low-concentration wastewater and then subjected to aerobic biochemical treatment, so that organic matters can be digested and degraded, and the wastewater is discharged after reaching the standard; compared with the method of mixing by introducing clean water, the method does not need to invest a large amount of equipment and energy for mixing and diluting, reduces energy consumption and operation cost, and improves treatment capacity.

In order to make the aforementioned objects, features and advantages of the present invention more clearly understood, the following detailed description of the present invention, taken in conjunction with the accompanying drawings and the detailed description, is given in a non-limiting manner.

As shown in figure 1, the sugar-making industrial wastewater treatment device comprises an oil separation tank, a cooling tower, an acidification tank, a regulating tank, a TLP anaerobic reactor, a settling tank, a neutralization tank, an oxidation ditch and a sedimentation tank which are sequentially communicated, wherein a dosing device is arranged beside the regulating tank, a lift pump is arranged between the regulating tank and the TLP anaerobic reactor, and an air outlet of a blast aerator is communicated in the oxidation ditch. The sugar industry wastewater treatment device also comprises a sludge concentration tank and a filter press, wherein a sludge port of the sedimentation tank is connected with an inlet of the sludge concentration tank, and an outlet of the sludge concentration tank is connected with an inlet of the filter press. Return pipes are communicated between the TLP anaerobic reactor and the settling tank and between the oxidation ditch and the sedimentation tank.

The specific steps of using the sugar industry wastewater treatment device to treat wastewater are as follows: introducing the high-concentration sugar-making industrial wastewater into an oil separation tank to remove suspended oil and heavy oil. Then sequentially entering a cooling tower to be cooled to the hydrolysis temperature, entering an acidification tank to be hydrolyzed, entering an adjusting tank to adjust the pH value to be neutral, entering a TLP anaerobic reactor to be subjected to anaerobic decomposition, and entering a settling tank to be subjected to first mud-water separation; supernatant obtained by the first mud-water separation enters a neutralization tank, and low-concentration sugar-making industrial wastewater is introduced into the neutralization tank for mixing; and (3) the mixed wastewater enters an oxidation ditch, activated sludge is utilized for carrying out catabolism, and then the wastewater enters a sedimentation tank for carrying out secondary mud-water separation, so that clear water which can reach the standard discharge is obtained. In the wastewater treatment process, the wastewater condition in the regulating tank is checked regularly, and if the flocs in the tank are small, the chemical adding device needs to be opened to ensure that the pH value of the wastewater passing through the regulating tank is neutral.
