Description
Technical field
The utility model belongs to sewage treatment area, particularly relates to a kind of equipment for the processing of printing-dying wastewater recycling technique Dyeing.
Background technology
China is maximum in the world fabric clothing production and export State, therefore dyeing is closely bound up with it, and the discharge of wastewater of dyeing is the major reason that causes water pollution, compare with other industry, it is large that dyeing waste water has a wastewater discharge, the characteristics such as color is dark, and hardly degraded organic substance content is high, and water quality is unstable.
For the processing problem of dyeing waste water, existing treatment technology mainly successively by materialization processing, biochemical treatment to treatment of dyeing wastewater, thereby the degraded objectionable impurities, reach emission standard.Materialization for present dyeing waste water is processed, and existing materialization treatment process is finished by operator's manual operations substantially.At first dyeing waste water is introduced in the pond, because the pH of dyeing waste water is uncertain, so generally with concentrated acid dyeing waste water is carried out the acidifying pre-treatment first, then regulate pH to alkalescence with lime, add again ferrous sulfate waste water is carried out the flocculation sediment processing.Because existing treatment of dyeing wastewater is simply equipped, the dyeing waste water water displacement is large, change of water quality is large, thereby workman's operation easier is high, labour intensity is large, thereby the pH alkaline conditioner appears in operative employee's easy error and the control of ferrous sulfate chemicals treatment amount is improper, not only waste material, also cause the water quality after final materialization is processed still unstable, affect the effect of follow-up biochemical treatment, even also can cause secondary pollution.
Summary of the invention
Goal of the invention of the present utility model provides a kind of novel structure, and is easy to operate, and level of automation is high, and handiness is good, the equipment for the treatment of dyeing waste water that treatment effect is good.
In order to realize the foregoing invention purpose, the utility model has adopted following technical scheme:
For the treatment of the equipment of dyeing waste water, this equipment comprises the first sewage treatment tank, the second sewage treatment tank, basic agent volume pump, the pH transmitter with pH meter, coagulating agent volume pump, turbidimetry system and PLC; The first sewage treatment tank is provided with water inlet, and the first sewage treatment tank output terminal connects the second sewage treatment tank by pipeline, sets out the mouth of a river on the second sewage treatment tank; Described basic agent volume pump and pH transmitter are installed on the first sewage treatment tank, and the signal output part of pH transmitter connects the input terminus of PLC, and the upper corresponding output terminal of PLC connects the basic agent volume pump; Described coagulating agent volume pump and turbidimetry system are installed on the second sewage treatment tank, the turbidimetry system comprises turbidity transmitter and is immersed in the interior turbidity transducer of the second sewage treatment tank dyeing waste water, turbidity transducer connects turbidity transmitter, the turbidity transmitter signal output part connects another input terminus of PLC, and upper another the corresponding output terminal of PLC connects the coagulating agent volume pump.
As preferably, also comprise stirrer, described stirrer is installed between coagulating agent volume pump and the turbidimetry system.Further, described turbidity transducer lower end is turbidity probe tip, and the stirrer bottom is stretched in the second sewage treatment tank dyeing waste water, and the stirring rake position of stirrer lower end is corresponding with turbidity probe tip and be in the turbidity probe tip front side.
As preferably, the corresponding turbidity probe tip of described the second sewage treatment tank sidepiece position is provided with a form.
Adopted the equipment of technique scheme, this equipment comprises being in the first sewage treatment tank by basic agent volume pump and pH transmitter and connects respectively the pH control process that controller consists of, be in the second sewage treatment tank and respectively connect controller by coagulating agent volume pump and turbidimetry system and consist of the secondary control process, automatically control by two-stage, the first step basic agent is regulated pH to weakly alkaline, again with coagulating agent with the alkali substance reaction in the dyeing waste water, produce muddy micro-floccule, system detects in real time by turbidimetry, the injected volume of control coagulating agent volume pump, thereby realize accurately controlling flexibly water quality, process stable, effective, be convenient to further biochemical treatment of dyeing waste water.As seen the advantage of the equipment of this treatment of dyeing and printing is: novel structure, and level of automation is high, and operation is stable, and treatment effect is good.
