The invention relates to a combined-type fiber gridding rib layer product and a preparation method of the combined-type fiber gridding rib layer product. The combined-type fiber gridding rib layer product comprises a plurality of layers of fiber gridding cloth, the fiber gridding cloth is spliced by a sizing agent, and the plurality of layers of fiber gridding cloth is combined to the gridding rib layer in a stacked manner. The combined-type fiber gridding rib layer product is combined by adopting the plurality of layers of fiber gridding cloth, monofilament number and gridding density of sub-thread fiber bundle of the gridding rib layer are not limited by the fiber gridding cloth production process, reinforced density is greatly increased, the monofilament number of the sub-thread fiber bundle is reduced, the distribution uniformity of the ribs is improved, and the strength of a gypsum plaster board product and the levels of fire stability and fire endurance performance are effectively improved.

The invention provides a biochemical tubular reactor for water treatment. The biochemical tubular reactor for water treatment is suitable for sewage treatment and can solve the problems that in a biological method water treatment device, the effective microorganism concentration is low, the contact efficiency of microorganisms and sewage is low, and the biochemical reaction controllability is poor. The biochemical tubular reactor for water treatment comprises a tank body which is connected with a water inlet tube, and biochemical tubular reaction units are arranged in the tank body; the biochemical tubular reaction units comprise working tubes which are sequentially connected through connecting tubes, sewage treatment units are arranged in the working tubes, water inlets of the working tubes are formed in the tank body, and water outlets of the working tubes stretch out of the tank body through a water outlet tube. According to the biochemical tubular reactor for water treatment, reactor technology conditions are controllable, the flow velocity and the water distribution uniformity are improved, the strain utilization rate is promoted to be increased, and the sewage and strains are mixed and contacted fully; the effect that pollutants are removed by means of the microorganisms is significantly enhanced, biomass is increased, the activity of the biomass is improved, physical conditions and biochemical conditions of technology operation are guaranteed, and efficiency improving and consumption reducing of a system are achieved.
