Description

Plastic slice washing wastewater treatment system

Technical Field

The utility model relates to a waste water treatment device especially relates to plastics regeneration treatment's plastics section washing wastewater's purification treatment system.

Background

The beverage bottle is made of renewable plastic, and the recycling and regenerating treatment method comprises the steps of crushing the beverage bottle into sheets, washing, drying, melting in a high-temperature melting furnace, bracing, granulating and packaging. In the regeneration treatment, the washing wastewater is mixed with various organic matters, floccules, silt and other substances, cannot be directly recycled and cannot be directly discharged, otherwise, the washing wastewater has serious pollution to surrounding surface water and underground water. At present, the waste water is purified by usually adopting active carbon or quartz sand with excellent filtering efficiency, although the prior art method has the technical advantage of large treatment capacity, the following technical problems of the two seriously influence the application of the purification treatment technology: the used activated carbon belongs to dangerous waste and should be specially treated by a qualified department; the quantity of the back-washing water of the quartz sand is large, and the system load is heavy; both methods also have the technical problems of complicated treatment process, high cost and the like.

Disclosure of Invention

The invention aims to provide a plastic slice washing wastewater treatment system which has the advantages of simple subsequent treatment of filter materials, low cost, simple system structure, low investment and operation cost and stable water treatment.

The utility model provides a pair of plastic section washing wastewater treatment system technical scheme, its main technical content is: the utility model provides a plastics section washing effluent disposal system, this system composition include equalizing basin, flocculation and precipitation pond, flocculating agent head tank and clean water basin, connect waste water conveying pipeline between flocculation and precipitation pond and the equalizing basin of its below, be equipped with the elevator pump on the waste water conveying pipeline, flocculation and precipitation pond, the lower part of cell body is for sinking to collect and fights, cell body upper portion is equipped with the overflow weir, the outer overflow passage of overflow weir is connected to clean water basin top passway, the mud filter tank is the fluting of sinking to collect fill below, equalizing basin top, the inslot is provided with 120 mesh filter cloth layers, is provided with 80 mesh filter cloth layers in the sewage filter tank on clean water basin upper portion.

The utility model discloses a technical scheme of a plastic slice washing wastewater treatment system, which has simple system constitution, less investment, easy operation management, high and stable purification effect, adopts filter cloth which is easy to be repeatedly cleaned as filter material for water purification and filtration and sludge water filtration, has less cleaning water amount and is convenient for recycling; the filtered and purified water reaches the recycling quality standard, can be recycled as plastic slice washing water, the sludge filtered water automatically flows into the regulating tank, and participates in the next purification cycle together with the wastewater in the regulating tank, so that the recycling rate of the wastewater is improved, and the sludge can be used as a raw material for making bricks and the like.

Detailed Description

The utility model discloses a plastics section washing effluent disposal system, as shown in the figure, this system component includes equalizing basin 1, flocculation and precipitation pond 2, flocculating agent head tank 5 and clean water basin 3.

Wherein, flocculation and precipitation pond 2 is located equalizing basin 1 top, is connected with waste water conveying pipeline 6 between the two, and conveying pipeline 6 installs elevator pump 7, in this embodiment, the elevator pump specifically be the immersible pump. The washing wastewater in the adjusting tank 1 is sent into a flocculation and precipitation tank 2 through a wastewater conveying pipeline 6, a flocculating agent is added into the flocculation and precipitation tank 2 through a flocculating agent raw material tank 5 according to the measurement, a chemical flocculation method is taken as an example, polyaluminium chloride is used as the flocculating agent, the flocculating agent is added according to the proportion of ten thousandth of the mass of the wastewater, impurities are coagulated and precipitated in the flocculation and precipitation tank 2, and the wastewater is purified.

The sediment is collected in a sedimentation hopper 20 at the lower part of the tank body of the flocculation sedimentation tank 2, and the sedimentation sludge is discharged into a sludge filter tank 4 from the sedimentation hopper 20. The sludge filtering tank 4 is a groove opening arranged at the top of the adjusting tank 1, a 120-mesh filter cloth layer is arranged in the tank, sludge discharged by the settling hopper 21 enters the sludge filtering tank 4, filtered water enters the adjusting tank 1 and participates in the next purification cycle together with wastewater in the adjusting tank 1, and the sludge filtered by the sludge filtering tank 4 can be dried and used for making bricks and the like. An overflow weir 21 is arranged at the upper part of the flocculation sedimentation tank 2, and supernatant water after sedimentation in the flocculation sedimentation tank 2 enters the clean water tank 3 from the top of the clean water tank 3 through an overflow channel 8 outside the overflow weir 21. The sewage filtering tank 9 is arranged in a channel through which the settled supernatant flows into the clean water tank 3, a 80-mesh filter cloth layer is arranged in the tank of the sewage filtering tank, and the filtered clean water enters the clean water tank 3 and can be used as plastic slice cleaning water for recycling.
