A Study For Treatment Of Wastewater From Water Treatment Plant

With the serious shortage of the water resource,to meet object request of the environmental improvement,many water treatment plants are facing to the challenge of the disposition of the manufacturidg drainage.This paper is about the study of the treatment technology to the different type manufacturing drainage;according to the distributed character of the water plants in Dongguan Guangdong province.Based on the Scene detection,we study the conventronal treatment and the primary strengthen treatment individually,also about the discipline of discharge and the water quality character,we also study the composited treatment technology for the different type water and quality in the paper.The main content indudes the quality character of the different drainage muddy water and the function of sedimentation and concentration to the treatment effect;and the specific treatment technics to the plant muddy water.The main result of study contains:(1)The rate of sdid in the substrate sludge present directronal distribution in the horizontal sedimentation tank in the plants according to the spot of field monitoring to combine the request of the muddy water,propose the corrective measure to the present technics to spoil disposal.The result presents,the recycle of the back washing water can increase the turbidity of the ran water,but it can't affect the reqular running of the present technics.(2)On the base of the distribution character of the water treatment plant and sewage treatment works,we propose the new treatment technical solution.and the direct recycle of the filter back washing water,and the muddy water from the sedimentation tank dispose to the sewage treatment works.(3)Base on specific access point of the muddy water in the sewage treatment works,we analyze several treatment solution,and study systemicly about the critical control index to the treatment technics.(4)Ground on the different character type of the muddy water and their sedimental character,propose the comprehensive treatment solution to the third water plant and sewage treatment works.
