Description
Technical field
The present invention relates to the field of waste water treatment of yarn dyeing, relate in particular to a kind for the treatment of of dyeing wastewater reuse method.
Background technology
Dyeing waste water belongs in industrial wastewater compared with the one of refractory reason. Due to technology, economic dispatch reason, biology-physics improvement method that most adopts can only reach basic emission request. Although slightly decline in colourity, organic substance is just resolved into less material, these catabolite character are difficult to control also very difficult grasp, cannot ensure environment not produce harm. Existing wastewater treatment mode ability can not meet present situation or need of production in the future soon, along with the attention of country to energy-saving and emission-reduction and environmental pollution, for our offspring, how to ensure the minimizing discharge of dyeing waste water or do not discharge just to seem very necessary.
Summary of the invention
For existing deficiency, the object of this invention is to provide a kind for the treatment of of dyeing wastewater reuse method, adopt biological contact oxidation pond, a secondary BAF to carry out advanced treating, after processing, expect to filter by pottery again and separate with milipore filter, the water obtaining can utilize again, has solved the problem occurring in background technology.
The object of this invention is to provide a kind for the treatment of of dyeing wastewater reuse method, comprise the following steps:
Step 1: dyeing waste water is discharged in regulating reservoir all and its water yield and water quality, and the water of regulating reservoir enters in hydrolysis acidification pool and processes;
Step 2: the water in hydrolysis acidification pool is discharged in biological contact oxidation pond and carries out denitrogenation removal organic matter, and afterwards, waste water is discharged in sedimentation basin and precipitates and add bleaching agent bleaching, and the complete waste water of precipitate and decolorization enters in flotation tank;
Step 3: the precipitation of sedimentation basin is discharged in sludge-tank, sludge-tank supernatant is discharged in hydrolytic tank to be processed again, and after the mud in sludge-tank carries out press filtration, outward transport is processed;
Step 4: the water in flotation tank enters into the transition of intermediate pool I, enters into afterwards in BAF and further carries out biochemical treatment, and the water being disposed enters into intermediate pool II;
Step 5: the material filter of making pottery successively of the water in intermediate pool II filters and carries out film with milipore filter and separate, be discharged to afterwards in clear water reserviors stand-by, in the time preparing to use the water in clear water reserviors, line that it just can be put into production after ion-exchange treatment system is processed uses.
Further improve and be: the BAF in biological contact oxidation pond and step 4 in described step 2 all needs by air blast blowing is set.
Further improve and be: in described step 5, pottery material filter and milipore filter carry out backwash to it in the time filtering interval.
Further improve and be: in described step 2, biological contact oxidation pond is provided with at least 4 in parallel uses, in step 3, BAF is provided with at least 2 in parallel uses.
Beneficial effect of the present invention: this method first through all with its water yield and water quality, then the acidifying that is hydrolyzed improves to be convenient to carry out a biological contact oxidation pond after the biodegradability of waste water and to process and remove nitrogen and organic matter, precipitate afterwards and remove mud, supernatant in mud can be proceeded to process again, reduce the discharge of water, the waste water of having removed mud carries out secondary BAF and further carries out biochemical treatment, effectively reduce the residual COD in water, integrate biological oxidation and hold back suspended solid, save post precipitation pond (second pond), the waste water of secondary biological treatment is filtering and is separating the suspension and the particle that further filter out in water with milipore filter through pottery material, filter at pottery material the gap separating with ultra filtration it is carried out to backwash, effectively avoid its putty, treated water enters clear water reserviors and processes and just can directly use through ion exchange system before use, whole method is more excellent than former mode treatment effect, water through this kind of method processing can and re-use, and only produce and even do not produce on a small quantity discharge of wastewater in rivers, realize recycling of water, reduce environmental pollution, promote the well-being of mankind.
Detailed description of the invention
In order to deepen the understanding of the present invention, below in conjunction with embodiment, the invention will be further described, and this embodiment only, for explaining the present invention, does not form limiting the scope of the present invention.
The present embodiment provides a kind for the treatment of of dyeing wastewater reuse method, comprises the following steps:
Step 1: dyeing waste water is discharged in regulating reservoir all and its water yield and water quality, and the water of regulating reservoir enters in hydrolysis acidification pool and processes;
Step 2: the water in hydrolysis acidification pool is discharged in biological contact oxidation pond and carries out denitrogenation removal organic matter, and afterwards, waste water is discharged in sedimentation basin and precipitates and add bleaching agent bleaching, and the complete waste water of precipitate and decolorization enters in flotation tank;
Step 3: the precipitation of sedimentation basin is discharged in sludge-tank, sludge-tank supernatant is discharged in hydrolytic tank to be processed again, and after the mud in sludge-tank carries out press filtration, outward transport is processed;
Step 4: the water in flotation tank enters into the transition of intermediate pool I, enters into afterwards in BAF and further carries out biochemical treatment, and the water being disposed enters into intermediate pool II;
Step 5: the material filter of making pottery successively of the water in intermediate pool II filters and carries out film with milipore filter and separate, be discharged to afterwards in clear water reserviors stand-by, in the time preparing to use the water in clear water reserviors, line that it just can be put into production after ion-exchange treatment system is processed uses.
BAF in biological contact oxidation pond and step 4 in step 2 all needs by air blast blowing is set; In step 5, pottery material filter and milipore filter carry out backwash to it in the time filtering interval; In described step 2, biological contact oxidation pond is provided with 4 in parallel uses, and in step 3, BAF is provided with 2 in parallel uses.
This method first through all with its water yield and water quality, then the acidifying that is hydrolyzed improves to be convenient to carry out a biological contact oxidation pond after the biodegradability of waste water and to process and remove nitrogen and organic matter, precipitate afterwards and remove mud, supernatant in mud can be proceeded to process again, reduce the discharge of water, the waste water of having removed mud carries out secondary BAF and further carries out biochemical treatment, effectively reduce the residual COD in water, integrate biological oxidation and hold back suspended solid, save post precipitation pond (second pond), the waste water of secondary biological treatment is filtering and is separating the suspension and the particle that further filter out in water with milipore filter through pottery material, filter at pottery material the gap separating with ultra filtration it is carried out to backwash, effectively avoid its putty, treated water enters clear water reserviors and processes and just can directly use through ion exchange system before use, whole method is more excellent than former mode treatment effect, water through this kind of method processing can and re-use, and only produce and even do not produce on a small quantity discharge of wastewater in rivers, realize recycling of water, reduce environmental pollution, promote the well-being of mankind.
