The invention discloses a telecommunication broadband wireless network access method and wireless network access equipment and aims at providing a shared telecommunication wired access broadband to simultaneously provide a shared broadband access circuit service for wired broadband contracted users and public wireless roaming users. The invention uses the following method to realize the wireless broadband access: the public wireless roaming user can get an access to the wireless network access equipment through a special wireless interface; and after the necessary information processing, the public wireless roaming user can get an access to operator certificate and service devices via a broadband route rented by the wired user to complete the data recovery, security certificate and public network service provision. The wireless network access equipment comprises more than one wireless circuit access modules which can identify internal users and public roaming users through special design; the wireless network access equipment can lead the identified internal users to be linked with an internal local area network firstly; and for identified external roaming users, the wireless network access equipment provides public network broadband services by building up a link which is connected with the certificate and service device of the telecommunication operator via a wired broadband circuit.

The invention belongs to the polyethylene oxide product production field, and particularly relates to a polymerization device in a production process of polyethylene oxide products; the polymerization device includes a polymerization kettle main body, a stirring device, a catalyst loading device, a shearing machine and a cooling device; the inner wall of the polymerization kettle main body is provided with at least four baffle plates along the circumference in a uniform distribution manner; the stirring device is arranged at a longitudinal central position of the interior of the polymerization kettle main body and adopts a three-layer push type stirring structure, wherein the length of first-layer stirring blades and second-layer stirring blades is 450 mm, and the length of third-layer stirring blades is 550 mm. Through special design of the baffle plates and the stirring device in the polymerization device, and through reasonable installation and use of the shearing machine, a phenomenon of local implosion generated by the reaction is avoided, so that the volume of the polymerization device is successfully amplified to 6000 L, and the production scale of the products is improved.

The invention discloses a dyeing waste liquid special treatment device and treatment method. The device comprises a settling chamber and a filtration-adsorption chamber, wherein the settling chamber is arranged above the filtration-adsorption chamber; a stirrer is arranged inside the settling chamber, the top of the settling chamber is provided with a waste liquid inlet pipe and a dosing pipe, and the bottom of the settling chamber is provided with a sludge discharge pipe; the settling chamber is also provided with a clear water discharge pipe; both the lower end of the clear water discharge pipe and the lower end of the sludge discharge pipe extend into the filtration-adsorption chamber; and at least one filtration-adsorption layer is arranged in the filtration-adsorption chamber. A special technique is utilized to organically combine stirring with settling and combine filtration with adsorption, thereby effectively reducing the technical process. The special design of the settling chamber and the filtration-adsorption chamber effectively avoids failures, thereby effectively lowering the operating cost of the company and increasing the sewage treatment efficiency.
