Preferably, comprise multiple membrane module between ultrafiltration, each membrane module is made up of multiple membrane element, and the membrane flux of each membrane element is 50LMH, and fenestra aperture is 0.01 ~ 0.1 μm.
Compared to existing technology, the beneficial effects of the utility model are:
(1) the utility model is only revised for the back segment of equipment for sewage treatment technology, does not substantially relate to the dismounting of former structures and pipeline, does not affect the normal operation of Sewage Plant;
(2) the utility model modularization, level of automation are high, and efficiency is high, and construction is fast, and operational management is convenient, and long service life, and Abschreibungskosten is low, and cost performance is high.
(3) low-concentration ammonia-nitrogen, organism, total phosphorus and the bacterial treatment effect removed difficulty of the utility model is good, stable effluent quality, by BAF, combination between efficient sedimentation tank and ultrafiltration, reduces the lower concentration BOD being difficult to remove further
5, the pollutent such as COD, TOC, have advanced nitrogen dephosphorization concurrently, the effect of disinfection, also reduce floor space to greatest extent, effectively solve with lower cost that to receive sewage body water quality requirement high, the contradiction that existing technique cannot meet, effluent quality can meet the requirement of " water environment quality standard " GB3838-2002 III class water body.

Embodiment
Below, by reference to the accompanying drawings and embodiment, the utility model is described further:
A kind of sewage tail water as shown in Fig. 1 ~ 2 carries mark advanced treatment system, comprise the coarse grid pond be communicated with successively, thin grid pond, settling pit, biochemical reaction tank, second pond, intermediate pool 1 (original reconstruction of filter tank) and sterilization outlet sump 5, BAF 2 is also communicated with successively, between efficient sedimentation tank 3 and ultrafiltration 4 between intermediate pool 1 and sterilization outlet sump, the water inlet of BAF 2 is connected with the water outlet of intermediate pool, and between ultrafiltration, the water outlet of 4 is connected with the water inlet of sterilization outlet sump 5.
As preferred embodiment, what BAF 2 comprised multiple parallel connection upwards flows through filter tank 21.This sewage tail water is carried mark advanced treatment system and is also comprised backwashing water discharge pond 6, and BAF 2 is built-in with back-purge system (not marking in figure), and the water inlet that water outlet and the backwashing water of this back-purge system discharge pond 6 is connected.Original reconstruction of filter tank is become intermediate pool 1, and for buffer storage sewage, water outlet preferably enters BAF 2 again after pumping plant promotes, and BAF 2 upwards flows through the filter tank parallel running of lattice more than 21 by multiple.The form of this employing upward flow, makes single lattice filtration area 56m
