Integrated domestic sewage treatment device

The invention provides an integrated domestic sewage treatment device. The interior of the main body of the device is sequentially divided into a pre-anoxic tank (B), an anaerobic tank (C), an anoxictank (D), an aerobic tank (E), a rear anoxic tank (F), a rear aerobic tank (G) and a membrane tank (H), and two adjacent tanks can realize overflow between two tanks through an overflow port between two tanks. The device further comprises an equipment pool (I), a contact disinfection pool (J) and a sludge pool (K). The maximum highlight of the integrated device is that pre-anoxia is added in the front section of an improved five-section Bardenpho process, and meanwhile, the technologies of sectional water inlet, two-stage denitrification and MBR membrane filtration are adopted, so that the effluent quality is better and more stable. 本发明提供了一种生活污水处理一体化装置，装置主体内依次区隔为预缺氧池(B)、厌氧池(C)、缺氧池(D)、好氧池(E)、后缺氧池(F)、后好氧池(G)、膜池(H)，相邻两池能通过两池之间的溢流口实现两池之间的溢流；还包括设备池(I)、接触消毒池(J)及污泥池(K)。本发明的一体化装置最大亮点是改良五段Bardenpho工艺前段增加预缺氧，同时采用分段进水、两级反硝化和
