The invention discloses preparation and an application of fixed-type bioactive fillers, and belongs to the technical field of water treatment. Fillers are each composed of a carrier and an embedding body, and the fillers are fixed on a prefabricated frame to form the fixed-type bioactive fillers; each carrier is composed of multiple layers of polyvinyl alcohol non-woven fabrics and one layer of textile fabric; each embedding body is formed by boric acid cross-linking fixation of an embedding liquid; the embedding liquid is formed by mixing an bacteria concentrated solution and a polyvinyl alcohol solution. Each carrier is soaked in the embedding liquid, the non-woven fabrics and the embedding body are firmly bound together through boric acid secondary cross-linking, the embedding body penetrates through textile fabric meshes to form a riveting fixing structure and does not easily fall off, and the good tensile property of the textile fabric improves the overall stability of the bioactive filler. The prepared bioactive fillers not only solve the problems that bacteria in an activated sludge method are low in concentration, easy to lose and the like, have the advantages of simple method, cheap raw materials, high strength, good stability, strong water flow shocking resistance ability and the like, shorten the reaction start-up time, and have broad application prospects.

The invention discloses a pressure-bearing integral metallurgy sewage purifying treatment device comprising a sealed pressure-bearing shell, wherein the shell is provided with at least two settling chambers, at least two flocculation reaction chambers and a hydraulic circulating clarifying chamber, and the settling chambers and the flocculation reaction chambers are staggered from bottom to top and are communicated in sequence; the lower end of each settling chamber is respectively connected with a blow-off pipe which extends to the outside of the shell; and the upper part and lower part of the shell are respectively provided with a discharging pipe and a water inlet pipe which extend to the outside of the shell. The treatment device can ensure stable purification effect and strong water impact resistance, has less possibility of being blocked, and is simple and convenient for maintenance; and the fully-sealed pressure-bearing integral metallurgy sewage purifying treatment device can fully utilize the residual pressure of coming water, and water produced by the device can be sent to a pressure filter or a cooling tower with no need of a secondary pressurizing pump station.

The invention provides trentepohlia artificial grass and application thereof on coupling with ammonia nitrogen sewage treatment and carotenoid production. A large trentepohlia plant body is cut into fragment-shaped algal filaments, the fragment-shaped algal filaments are thickened, and then are inoculated into films so as to prepare the trentepohlia artificial grass; and the artificial grass is coupled with ammonia nitrogen sewage treatment and carotenoid production. Compared with the prior art, the trentepohlia artificial grass has the advantages that a selected trentepohlia film-forming method is simple, film-forming efficiency is high, and after being formed, the trentepohlia artificial grass is attached firmly, has quite high water impact resistance, and can grow in a water submergingor semi-submerging state. The algal filaments in the prepared trentepohlia artificial grass are in the shape of a stereo net which is upright mainly, the thickness reaches 10 mm, and the specific surface area of a whole biological film is large. The selected trentepohlia has efficient removal rate on ammonium nitrogen, has ability of resisting high-concentration ammonium nitrogen and a strong acidenvironment, and even can directly treat livestock and poultry breeding sewage and sanitary sewage. Steps are simple, and the trentepohlia artificial grass is convenient to operate and high in practicality.

The invention relates to a three-section all-in-one rectangular anaeroic digestor comprising a distribution region, a reaction region and a three-phase separation region, wherein the cross section of the digestor is rectangular and respectively provided with the distribution region, the reaction region and the three-phase separation region from bottom to top, and the distribution region, the reaction region and the three-phase separation region are integrated; the distribution region comprises a bottom plate, the lower part of a side wall and a feeding pipe, wherein the upper surface of the bottom plate is connected with the side wall lower part; the reaction region is defined by the middle of the side wall, two sides inside the reaction region are oppositely provided with a first baffle plate and a second baffle plate from bottom to top, the reaction region is divided into three region chambers, and a gas collecting chamber is arranged at the upper part of each region chamber; and the three-phase separation region comprises the upper part of the side wall, an overflow veir, a three-phase separation baffle, a restricted baffle and a top cover, wherein the top cover is respectively provided with three gas collecting holes corresponding to the three gas collecting chambers, and the gas collecting holes are used for collecting the generated biogenic gas. The three-section all-in-one rectangular anaeroic digestor is compact in structure, convenient for manufacturing, easy to realize industrialization, uniform in distribution, not easy to block, high in treatment efficiency, good in liquid-solid mass transfer effect, high in organic load impact resistance and also capable of fractionally collecting the biogenic gas.
