Abstract
The invention discloses a desizing wastewater treatment device. The desizing wastewater treatment device comprises a temporary storage tank, a neutralizing reaction tank and a deposition tank, wherein a wastewater inlet pipe is arranged at the front end of the temporary storage tank; a filter net is arranged in the water flow direction in the temporary storage tank; the tail end of the temporary storage tank is connected with one end of the neutralizing reaction tank through a water pipe; the other end of the neutralizing reaction tank is connected with the deposition tank through the water pipe; an active carbon filter is arranged on a water outlet pipe of the deposition tank; 2-4 filter nets are arranged in the temporary storage tank; and an alkaline liquor conveying pipe is arranged above the neutralizing reaction tank. The desizing wastewater treatment device has the beneficial effects that: 1, all water discharge indexes meet the requirements of national and local related water quality standards; 2, a system is simple and reliable to run, safe, and convenient to operate; and the running and investment costs are reduced; 3, the select treatment process is short, and the feasibility, impact resistance and treatment effects are stable; and 4, 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 desized wastewater 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 desized wastewater, and the water yield is less, and Pollutant levels are high, mainly contain slurry and resolvent thereof, fiber flock, acid, starch alkali and enzyme pollutent, and turbidity is big.Waste water is alkalescence, and the pH value is about 12.BOD, COD are all high during with starch size, good biodegradability; COD is very high during with synthetic slurry, and BOD is less than 5mg/L, and the water biodegradability is relatively poor.Reclamation rate does not also reach 7% 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 desized wastewater treatment unit.
In order to solve the problems of the technologies described above, the present invention adopts following technical scheme:
A kind of desized wastewater treatment unit; This device comprises temporary tank, neutralization reaction groove and settling bath; The front end of said temporary tank is provided with wastewater inlet pipe, is provided with filtering net along water (flow) direction in the temporary tank, and the end of temporary tank is connected with an end of neutralization reaction groove through water pipe; The other end of said neutralization reaction groove is connected with settling bath through water pipe, and the rising pipe of said settling bath is provided with activated charcoal filter.
Be provided with 2-4 filtering net in the said temporary tank.
Said neutralization reaction groove top is provided with the alkali lye 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.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Among the figure: 1 is temporary tank, and 2 is the neutralization reaction groove, and 3 is settling bath, and 4 is filtering net, and 5 is the alkali lye transfer lime, and 6 is activated charcoal filter.
