Further, this polyester waste water treatment system also comprises reflux pump first and reflux pump second, and described reflux pump first is arranged between described settling tank first and A section activated sludge tank, and described reflux pump second is arranged between described settling tank second and B level aerobic aeration pond.
Further, this polyester waste water treatment system also comprises recoil pump, and the input terminus of described recoil pump is connected with described discharge pond, and output terminal is connected with described strainer and active carbon adsorber respectively.
Further, this polyester waste water treatment system also comprises sludge thickener, sludge modification device and sludge filter press, described sludge thickener is connected with described reflux pump first, reflux pump second, comprehensive adjustment pond and sludge modification device respectively, and described sludge modification device is arranged between described sludge thickener and sludge filter press.
Compared with prior art, the beneficial effects of the utility model are:
1, employing UASB reaction tank of the present utility model, its inner anaerobic sludge concentration is high, Sludge Bed does not establish carrier, save cost and avoid because of filler generation blockage problem, be provided with triphase separator in UASB, usually do not establish settling tank, the mud that precipitated district separates comes back in Sludge Bed reaction zone, usually can not establish sludge reflux equipment, run power lower;
2, comprehensive adjustment pond of the present utility model is mixed sanitary wastewater and polyester waste water, UASB reactor is entered after eddy flow mixing reactor and intermediate pool first are neutralized to PH8-8.5, at utmost can supplement the nutritive elements such as N and P in waste water, ensure that last water purification effluent quality;
3, be provided with A section activated sludge tank and B level aerobic aeration pond in the utility model, its waste water treatment efficiency is high, especially in high concentrated organic wastewater process, and stable, construction investment economize and working cost low, have good development prospect.
Accompanying drawing explanation
Accompanying drawing is structural representation of the present utility model.
