Abstract
The invention relates to a printing and dyeing sewage processing system having beautiful design, reasonable arrangements and reduced noise, and capable of reasonably disposing solid waste, improving environment of a sewage station and the environment nearby the sewage station, and preventing secondary pollution. The printing and dyeing sewage processing system comprises a machinery grate, a regulating reservoir, an air floatation water purifier, a CASS tank, a clean water tank, a sludge well, a sludge thickening tank and a dehydrator. The machinery grate, the regulating reservoir, the air floatation water purifier, the CASS tank and the clean water tank are sequentially connected via pipelines. The CASS tank, the sludge well, the sludge thickening tank and the dehydrator are sequentially connected via pipelines. An elevator pump is arranged on the pipeline arranged between the regulating reservoir and the air floatation water purifier. A sludge pump is arranged on the pipeline arranged between the sludge well and the sludge thickening tank, and a sludge pump is also arranged on the pipeline arranged between the sludge thickening tank and the dehydrator. The air floatation water purifier is connected with the sludge thickening tank through a pipeline, and a sludge reflux pipeline is arranged between the CASS tank and the sludge well.
Description
Technical field
The present invention relates to a kind of dyeing and printing sewage treatment system.
Background technology
Needs due to production technique, printing and dyeing workshop will discharge a certain amount of waste water, in these waste water, contain a large amount of organism, colourity, sulfide, dye well part of auxiliary, alkali etc., these waste water certainly will cause severe contamination to surrounding environment without the direct discharge of any processing, and the feature of waste water is that concentration is high, the water yield large, waste water BOD5/CODcr=0.25～0.3 biodegradability belongs to general.
Summary of the invention
The object of this invention is to provide a kind of dyeing and printing sewage treatment system, be designed beautifully, rationally distributed, reduce noise and reasonable disposal of solid waste, improve sewage plant and surrounding environment, avoid secondary pollution.
Dyeing and printing sewage treatment system of the present invention, comprise mechanical grille, equalizing tank, air-floatation water purifier, CASS pond, clean water basin, sewer catch basin, sludge thickener, water extracter, mechanical grille, equalizing tank, air-floatation water purifier, CASS pond is connected by pipeline successively with clean water basin, CASS pond, sewer catch basin, sludge thickener is connected by pipeline successively with water extracter, on pipeline between equalizing tank and air-floatation water purifier, be provided with lift pump, on pipeline between sewer catch basin and sludge thickener, be provided with sludge pump, on pipeline between sludge thickener and water extracter, be provided with sludge pump, air-floatation water purifier is connected by pipeline with sludge thickener, between CASS pond and sewer catch basin, be provided with sludge return pipe.
The technological processs such as the CASS Chi Ji the present invention relates to just sinks, aeration, two sinks are in one; CASS system is an interval type reactor, and in this reactor, activated sludge process process constantly loops by aeration and non aerated phases.This method concentrates on bioprocesses and mud-water separation process in a pond and carries out.Each circulation was comprised of following each stage:
(1) water-filling/aeration, (2), without water inlet/precipitation, (3) skim water, and (4) are idle.The CASS pond cycle of operation generally has 4 hours and 6 hours two kinds of forms, and the cycle of operation can regulate according to flooding quantity.For keeping there is a suitable sludge concentration in pond, need to discharge excess sludge according to the sludge quantity producing; Discharge excess sludge and generally after precipitate phase finishes, carry out, discharge sludge concentration and can reach 10g/l.
Compared with prior art beneficial effect of the present invention is:
Dyeing and printing sewage treatment system of the present invention, adopting physico-chemical process is main treatment process in conjunction with biochemical process, adopt the auxiliary treatment techniques such as mechanical grille interception, solid-liquid separation simultaneously, be designed beautifully, rationally distributed, reduce noise and reasonable disposal of solid waste, improve sewage plant and surrounding environment, avoid secondary pollution.
Accompanying drawing explanation
Fig. 1 is the process flow sheet of dyeing and printing sewage treatment system of the present invention.
Embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present invention is described in further detail.Following examples are used for illustrating the present invention, but are not used for limiting the scope of the invention.
As shown in Figure 1, a kind of dyeing and printing sewage treatment system, comprise mechanical grille 1, equalizing tank 2, air-floatation water purifier 3, CASS pond 4, clean water basin 5, sewer catch basin 6, sludge thickener 7, water extracter 8, mechanical grille 1, equalizing tank 2, air-floatation water purifier 3, CASS pond 4 is connected by pipeline successively with clean water basin 5, CASS pond 4, sewer catch basin 6, sludge thickener 7 is connected by pipeline successively with water extracter 8, on pipeline between equalizing tank 2 and air-floatation water purifier 3, be provided with lift pump, on pipeline between sewer catch basin 6 and sludge thickener 7, be provided with sludge pump, on pipeline between sludge thickener 7 and water extracter 8, be provided with sludge pump, air-floatation water purifier 3 is connected by pipeline with sludge thickener 7, between CASS pond 4 and sewer catch basin 6, be provided with sludge return pipe.
Waste water is collected to equalizing tank after the above floating matter of mechanical grille interception 5mm, waste water is pumped to air-floatation water purifier with pump after catchmenting at this, by the screen cloth interception above fine suspension of 1mm (staple fibre), and reclaim insoluble staple fibre to guarantee the safe operation of follow-up equipment.After carrying out materialization processing after air-floatation water purifier dosing coagulation, water outlet gravity flow enters CASS pond, and the mud in CASS pond enters sewer catch basin, and part, as returned sluge, is delivered to CASS pond by sludge return pipe.All the other excess sludges and air-floatation water purifier are discharged mud and are delivered to sludge thickener, and mud is submitted to sludge dewatering equipment by sludge pump after concentration and settlement at sludge thickener, outward transport after dehydration.
The technological processs such as the CASS Chi Ji the present invention relates to just sinks, aeration, two sinks are in one; CASS system is an interval type reactor, and in this reactor, activated sludge process process constantly loops by aeration and non aerated phases.This method concentrates on bioprocesses and mud-water separation process in a pond and carries out.Each circulation was comprised of following each stage: (1) water-filling/aeration, and (2), without water inlet/precipitation, (3) skim water, and (4) are idle.The CASS pond cycle of operation generally has 4 hours and 6 hours two kinds of forms, and the cycle of operation can regulate according to flooding quantity.For keeping there is a suitable sludge concentration in pond, need to discharge excess sludge according to the sludge quantity producing; Discharge excess sludge and generally after precipitate phase finishes, carry out, discharge sludge concentration and can reach 10g/l.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, do not departing under the prerequisite of the technology of the present invention principle; can also make some improvement and modification, these improve and modification also should be considered as protection scope of the present invention.
