Abstract
The invention discloses a boiling and smelting wastewater treatment device which is characterized by comprising a filtering tank, a sand filtering tank, a neutralization reaction pool and a sedimentation tank. A wastewater inlet pipe is arranged at the front end of the filtering tank, the filtering tank is connected with the top end of the sand filtering tank through a pipeline, a coarse sand layer, a medium sand layer and a fine sand layer are sequentially arranged in the sand filtering tank from top to bottom, the bottom end of the sand filtering tank is connected with the front end of the neutralization reaction pool through a pipeline, the tail end of the neutralization reaction pool is connected with the front end of the sedimentation tank through a pipeline, and a water outlet pipe is arranged at the tail end of the sedimentation tank. The boiling and smelting wastewater treatment device has the advantages that each effluent index meets the national and local relevant water quality standard requirements; the device is simple and reliable in systemic operation, safe, convenient to operate and lower in operation cost and investment cost; the device is short in selective processing technological process, feasible, impact resistant and stable in treatment effect; and the device is convenient to operate, manage and maintain.
Description
Technical field
The invention belongs to the dyeing apparatus technical field, be specifically related to a kind of boiled-off waste water treatment unit.
Background technology
Dyeing waste water is that processing cotton, fiber crops, man-made fiber and blending product thereof are the waste water that main printing and dyeing mill discharges.The dyeing waste water water yield is bigger, 100～200 tons of 1 ton of textiles water consumptions of every printing and dyeing processing, and wherein 80～90% become waste water.And one of dyeing waste water is a boiled-off waste water, and the water yield is big, and Pollutant levels are high, mainly contain Mierocrystalline cellulose, tartaric acid, wax, grease, alkali, tensio-active agent, nitrogenous compound etc.Waste water alkalescence is very strong, and water temperature is high, is brown, and COD and BOD are very high, reaches every liter of thousands of milligram.The pollution of man-made fiber boiled-off waste water is lighter.Reclamation rate is very low after the WWT so far, and simultaneously, because China is the country of a famine water resources, limited water resource has also determined dyeing must walk the road of recycling economy development.
Summary of the invention
The object of the present invention is to provide a kind of boiled-off waste water treatment unit.
In order to solve the problems of the technologies described above, the present invention adopts following technical scheme:
A kind of boiled-off waste water treatment unit; It is characterized in that: this device comprises filtering basin, sandfiltration pot, neutralization reaction pond and settling tank; The front end of said filtering basin is provided with wastewater inlet pipe; Filtering basin are connected with the top of sandfiltration pot through pipeline, are provided with coarse sands layer, middle layer of sand and fine sand layer in the sandfiltration pot from top to down successively, and the bottom of sandfiltration pot is connected with the front end in neutralization reaction pond through pipeline; The tail end in said neutralization reaction pond is connected with the front end of settling tank through pipeline, and the tail end of said settling tank is provided with rising pipe.
The top of said settling tank is provided with the drug bucket that adds of storage coagulant aids.
Said neutralization reaction groove top is provided with the acid solution transfer lime.
Beneficial effect of the present invention:
1, each item effluent index meets the requirement of country and local relevant water quality standard;
2, system's operation is simple and reliable, safe, easy to operate, reduces running cost and investment cost;
3, select processing technological flow weak point, feasibility, shock-resistant, treatment effect to stablize;
4, convenient operation and management, be convenient to safeguard.
