Abstract
A system for treating and cyclically utilizing the waste water from laundering and dyeing field can perform such steps as coarse filter, settling, adsorption, sterilization and regulating water quality for reuse. The fibrous substances, oily dirt, dust and organic substance can be removed from water and the water can also be decoloured. Its advantages are low cost, simple treating process, and high reclaiming rate up to 80% or more.
Description
The present invention relates to a kind of Waste Water Treatment, specifically a kind of laundering and dyeing trade wastewater treatment and cyclic utilization system
At present, the waste water major part that is produced in the laundering and dyeing trade at home is disposable discharging, and promptly waste water resource causes serious environmental to pollute again.Chinese patent literature CN1179488A, name is called: the washing machine with electrolytic sewage disposal apparatus, it has waste disposal plant, this waste disposal plant use electrolysis process remove be contained in the sewage such as tensio-active agent, suspended solids and organic dirt, thereby the sewage after the washing is carried out self-purification.This electrolytic sewage disposal apparatus comprises sewage treatment tank, and it has the inlet of the sewage that is used to the row's of reception self-stip container, outlet that the sewage that is used for handling is discharged and the treatment chamber that is used to dispose of sewage.The electrode part has an antianode and negative electrode at least, and these electrodes are spaced from each other, and relatively are arranged in the sewage treatment tank mutually.This waste disposal plant adopts electrolytic method, and is the integral part of washing machine.And for generations such as laundry wash the waste water that dyes usefulness in a large number, be specially adapted to the centralized dyer factory of washing, also lack highly professional Waste Water Treatment.
The object of the present invention is to provide a kind of special wastewater treatment equipment, will wash to dye and separate, purify to reach water, and reuse, save water resources, reduce to wash and dye this with pollutants in waste water; Its installation cost is lower, and handling procedure is simple, and easy handling is specially adapted to the centralized dyer factory of washing.The objective of the invention is to realize by following scheme.
A kind of laundering and dyeing trade wastewater treatment and cyclic utilization system, this system regulates water quality after washing and dyeing wastewater is passed through coarse filtration, precipitation, absorption, sterilization and adjusting pH value, water hardness, repeats to wash after the processing to dye again.Coarse filtration adopts the reticulation filtration, and precipitation adopts chemical substance such as alum to leave standstill or impels precipitate, and absorption can be adopted the activated carbon adsorption strainer, and sterilizing agent is adopted in sterilization, after the pH value of mensuration waste water, the water hardness, regulates water quality.The discharge of wastewater that dyes will be washed in the coarse filtration groove that reticulation is set by this system, enter into settling bath through water outlet, added in the settling bath as chemical substances such as alum and left standstill or impel precipitate, again by behind a plurality of activated carbon adsorption strainers, enter into the catch basin that adds sterilizing agent, measure pH value, the water hardness of the waste water after handling in the catch basin, regulate the pH value and be 6～8, below the water hardness 70ppm, repeat again to wash to dye.
Effect of the present invention, because this system is only limited to the wastewater treatment of laundering and dyeing trade, so the water-quality ratio of waste water source is more close, wastewater treatment equipment is highly professional, processing cost is 1/3 of a common cost of sewage disposal.This system adopts coarse filtration, precipitation, absorption, sterilization and regulates water conditioning, the fibre object in the washing and dyeing wastewater, grease, dust, organism can be removed, and can also make water decolorization, deodorization, reaches the degree of recycling.Its installation cost is lower, and handling procedure is simple, and easy handling is specially adapted to the centralized dyer factory of washing.The recovery utilization rate of water reaches more than 80%.
The present invention has following accompanying drawing.
Fig. 1 is the schema of laundering and dyeing trade wastewater treatment and cyclic utilization system.
Below in conjunction with accompanying drawing to the detailed description of the invention.
Embodiment.
The schema of laundering and dyeing trade wastewater treatment and cyclic utilization system, as shown in Figure 1.Washing and dyeing wastewater removes by filter fibre object through the coarse filtration groove 1 that is provided with reticulation, impurity etc., adopt chemical substance such as alum etc. to put into settling bath 2, the sewage of coarse filtration is left standstill or impel its precipitation, by three charcoal filters 4,5,6, the Filtration Adsorption pigment, grease etc., according to handling what of waste water, adopt one or two or three charcoal filter, catch basin 7 has added sterilizing agent, waste water is carried out disinfection, by measuring the pH value of the waste water after handling in the catch basin 7, water hardness, regulating the pH value is 6～8, below the water hardness 70ppm, recycling is washed and is dyed.
Claims (7)
1. laundering and dyeing trade wastewater treatment and recycle method is characterized in that will washing and dyeing wastewater repeating to wash to dye after through coarse filtration, precipitation, absorption, sterilization and the processing of adjusting pH value again.
2. the method for claim 1 is characterized in that coarse filtration adopts reticulation to filter.
3. the method for claim 1 is characterized in that precipitation adopts chemical substance such as alum to leave standstill or impels precipitate.
4. the method for claim 1 is characterized in that adsorbing and can adopt the activated carbon adsorption strainer.
5. the method for claim 1 is characterized in that sterilization employing sterilizing agent.
6. the method for claim 1 is characterized in that adopting and measures through after the waste water ph after coarse filtration, precipitation, the absorption, the water hardness, regulates water pH value and be 6～8, water hardness is below 70ppm.
7. laundering and dyeing trade wastewater treatment and cyclic utilization system, it is characterized in that to wash the discharge of wastewater that dyes in the coarse filtration groove (1) that reticulation is set, enter into the settling bath (2) that has added as chemical substances such as alum through water outlet, again by behind a plurality of activated carbon adsorption strainers (4,5,6), enter into the catch basin (7) that adds sterilizing agent, measure pH value, the water hardness of the waste water after handling in the catch basin (7), regulate the pH value and be 6～8, water hardness below 70ppm, repeat again to wash to dye.
