Sewage treatment process
◆ sewage treatment process
To produce a certain amount of mud in sewage work's biological wastewater treatment process, contain a certain amount of organism in this part mud, if the mishandling water body that enters again also with the dissolved oxygen in the consume water, causes secondary pollution.Therefore, sludge treatment is one of important content of Sewage Plant, and the processing requirements that general sewage disposal produces mud is as follows:
Reduce the organism in the mud, make mud realize stabilization;
Reduce sludge volume, reduce traffic capacity;
Utilization is to realize recycling sludge;
Sludge of sewage treatment plants is handled generally two kinds of forms, and the one, digestion reconcentration dehydration earlier, the 2nd, direct thickening.Because this engineering treatment scale is less, because of Digestive tract is generally used for large-scale wastewater treatment plant, and investment is high, and control is complicated, and therefore the security requirement height is considered to adopt direct thickening technology that mud is subtracted to hold usually and handled.
◆ the mud concentration technology
Mud concentrates mode, and to mainly contain that gravity concentrates, air supporting concentrates, machinery concentrates etc. several.The concentrated employing of gravity is more, and air supporting concentrates and the concentrated employing of machinery is less, but the trend that increases is arranged this year.Air supporting concentrates and to be used in the dephosphorization process morely, and its facility investment is many, and power consumption is higher, management, safeguards trouble, and investment is big, and is not suitable for this engineering.It is more that machinery concentrates an external application, generally need import equipment, so facility investment is bigger, and after sale service is difficult to guarantee.And traditional gravity concentrates, and effect stability is reliable, can satisfy this engine request fully.
Therefore, this engineering mud concentrates and recommends to adopt the gravity concentration technology.
◆ dewatering technology of mud is selected
Mud after concentrating is because water content is still very high, bulky, and it is easily corrupt smelly, be unfavorable for transportation and disposal,, can reduce the water ratio of mud like this so need carry out processed, reduce the volume of mud, reduce transportation cost, concentrated back mud commonly used can utilize the content of material to increase (as agricultural fertile part, the calorific value that burns etc.), and is beneficial to the follow-up disposal and the utilization of mud.Mud dewatering method commonly used has two kinds of nature mummification and mechanical dehydrations, and seasoning is to utilize a kind of usual way of elements (as sun power) with sludge dehydrating and drying, and commonly used is sludge drying bed traditionally.This method is applicable to that weather is relatively drier, occupation of land takes it easy and the area of environmental health conditions permit, in the less employing of Sewage Plant.Mechanical dehydration is the method that generally adopt present countries in the world.Dewatering machine commonly used has vacuum filter, plate-and-frame filter press, belt filter press and centrifuge.In this year, bowl centrifuge and belt filter press are developed rapidly, are used widely in countries in the world as the main machine of sludge dewatering.
The more three kinds of modes that have are used in sludge dewatering at present, the one, plate-and-frame filter press, the 2nd, centrifuge, the 3rd, belt filter press, see that with regard to dehydrating effect the water ratio of plate-and-frame filter press dehydrated sludge is minimum, can reach 70%-75%, centrifuge and belt filter press are suitable, and water ratio can reach about 75-80%.With regard to construction costs, sheet frame: centrifugal: belt=100: 70: 40.Therefore, the cost performance of belt filter press is best.
Through above-mentioned comparison, and the running condition of domestic dehydration type, this engineering adopts belt filter press.
◆ the sludge disposal mode
Mud disposal options commonly used has burning, landfill or is used for soil improvement.
Contain chemical agent because dyeing waste water produces mud more, should not consider that temporarily transporting outward landfill disposes as soil improvement or incineration disposal.
Water outlet and integrated wastewater discharge standard GB8978-1996 primary standard specific targets after printing and dyeing arrangement industry, the process hides processing industry production wastewater treatment are as follows:
CODcr≤70-85mg/L
BOD5≤20mg/L
SS≤50mg/L
PH＜6-9
Colourity＜50
