Below respectively the characteristics of high dense settling pond and fabric filter are made a brief description.
(1) high dense settling pond
High dense settling pond is a kind of employing dosing coagulation, the coacervation by the development of the sharp full company of France Germany, the reaction inclined tube precipitation, and the settling pond rapidly and efficiently of part mud Recycle design, its principle of work is based on following several respects:
Integration mixing coacervation reaction on the protonotion.
The pulling flow type reaction tank is to the transmission at a slow speed between the settling tank.
The external recirculation system of mud.
Inclined tube (swash plate) precipitation process.
Adopt synthetic flocculation agent+polymer coagulant aids.
The use range of high dense settling pond is wide, can be regarded as " omnipotent " settling pond, can be applicable to following aspect:
(1) drinks water clarification, de-carbon;
(2) city domestic sewage is just changed settling tank, three dephosphorization;
(3) special processing of industrial sewage;
(4) concentration of mud;
Processing parameter and characteristics:
Because form homogeneous flocs unit and high-density alumen ustum, sedimentation speed can arrive 15～40m/h.And it is concentrated to finish mud effectively, and the effluent characteristics of post precipitation is higher, generally in 10NTU.Capacity of resisting impact load is strong, can not change because of the variation of burst impact load, can move under flow velocity fluctuates big situation.
(2) fiber filter
The basic point of fiber filter is the filter tank that filtrate adopts filtrates such as fibrous nodules, fiber yarn, fibrous bundle, its filtering velocity generally can reach 20-25m/h, reach as high as 30m/h, because the application of fiber dimensional filter is existing historical for many years, especially developed recently is very fast, filtering velocity is 2-3 a times of conventional filter tank, municipal effluent and the industrial sewage that is suitable for municipal effluent mutually can further can be handled better water quality condition by this art breading.
(3) combined sewage treatment system of the present invention has been used the advantage and the characteristics of these two kinds of treatment process just, with the high sedimentation speed 15-40m/h of high dense settling pond and the high filtering velocity 20-25m/h of fiber filter, because both speed is close or identical, both are organically combined, bring into play its advantage and characteristics jointly, be combined to form a kind of advanced person's sewage disposal device.
Sewage treatment process of the present invention as shown in Figure 2.
The part that the present invention does not relate to prior art that maybe can adopt all same as the prior art is realized.
