Multifunctional composite absorbing material for purifying water and preparation method thereof

The invention provides a multifunctional composite absorbing material for purifying water and a preparation method thereof, relating to an absorbing material. The invention provides the multifunctional composite absorbing material for purifying water, which can be used for effectively removing a plurality of harmful substances in the water and has higher removal efficiency and lower production cost, and the preparation method thereof. The absorbing material is selected from at least one of absorbing materials A, B and C; the absorbing material A takes a mesoporous adsorption ceramic material as a carrier to load nano metals including nano silver, nano zinc, nano iron and nano cerium; the absorbing material B takes the mesoporous adsorption ceramic material as the carrier to load nano metal oxides including nano titanium dioxide, nano zinc oxide, nano ferric oxide and nano cerium dioxide; and the absorbing material C is prepared from the following raw materials according to the mass ratio: 100-200 parts of active carbon powder, 20-30 parts of polyethylene powder, 10-30 parts of calcium sulfite powder, 10-30 parts of natural zeolite powder, 20-40 parts of macroporous acrylic resin and 10-20 parts of attapulgite powder.

A mobile station and methods are disclosed for diagnosing and modeling site specific effluent treatment facility requirements to arrive at a treatment regimen and/or proposed commercial plant model idealized for the particular water/site requirements. The station includes a mobile platform having power intake, effluent intake and fluid outflow facilities and first and second suites of selectably actuatable effluent pre-treatment apparatus. An effluent polishing treatment array is housed at the station and includes at least one of nanofiltration, reverse osmosis and ion-exchange stages. A suite of selectively actuatable post-treatment apparatus is housed at the station. Controls are connected at the station for process control, monitoring and data accumulation. A plurality of improved water treatment technologies is also disclosed. The modeling methods include steps for analyzing raw effluent to be treated, providing a field of raw effluent condition entry values and a field of treated effluent condition goals entry values, and utilizing said fields to determine an initial treatment model including a selection of, and use parameters for, treatment technologies from the plurality of down-scaled treatment technologies at the facility, the model dynamically and continuously modifiable during treatment modeling.

Rapid treatment method for fracturing flowback fluid

The invention discloses a rapid treatment method for a fracturing flowback fluid. The rapid treatment method comprises: (1) pumping a fracturing flowback fluid into an electron beam irradiation chamber, and staying for 20-120 s in the electron beam irradiation chamber; (2) adding a coagulant and a flocculant into the sewage treated by the electron beam irradiation chamber, and clarifying in a flocculation precipitation pool; (3) feeding the water treated by the flocculation precipitation a precision filtration pool, and carrying out fine filtration; and (4) collecting the water filtered by theprecision filtration pool in a clear water pool. According to the present invention, the gel breaking stage uses physical gel breaking so as to achieve clean gel breaking and greatly reduce the sideeffects of external agents, such that the reuse quality of the fracturing flowback fluid is good, and the fracturing flowback fluid is safe; the gel breaking time is shortened from 5-120 min to 20-120s so as to greatly improve the gel breaking speed; and compared with the traditional chemical gel breaking method and the biological gel breaking method, the method of the present invention simplifyfeeding equipment and other supporting equipment, reduces the occupation area, and reduces the complexity of manual operation.
