A membrane supported biofilm reactor uses modules having fine, hollow fibres, for example, made from melt spun thermoplastic polymers treated after spinning to increase their permeability to oxygen, used, for example, in tows or formed into a fabric. In one module, one or more sheets of the fabric are potted into a module to enable oxygen containing gas to be supplied to the lumens of the hollow fibres. Various reactors and processes, for example to treat wastewater, using such modules are described. Mechanical, chemical and biological methods, for example endogenous respiration, are used to control the thickness of the biofilm.

The invention discloses an application of mirabilis jalapa in purifying livestock and poultry culture biogas slurry, and belongs to the field of waste water treatment. The mirabilis jalapa is planted in the livestock and poultry culture biogas slurry polluted environment; and the characteristics that the absorption action of the mirabilis jalapa on polluted substances, such as NH4<+>-N, TN (total nitrogen), TP (total phosphorus), CODcr (Chemical Oxygen Demand Cr) and the like in the livestock and poultry culture biogas slurry, the mirabilis jalapa has tenacious vitality, can be directly planted, does not need special management and is perennial are fully utilized so as to permanently solve the pollution problem of the livestock and poultry culture biogas slurry. The mirabilis jalapa has the advantages of small investment, low operation cost and good effect, is simple to operate and is easy to realize, and the winter purification effect of the artificial wetland system can be guaranteed. The harvested mirabilis jalapa can dispel the wind, invigorate the circulation of blood, and treat stranguria with turbid urine, profuse leucorrhea, pulmonary labor hematemesis, ulcer on the back, acute arthritis, pulmonary labor hemoptysis and the like. When the mirabilis jalapa is used for treating waste water, environment protection and economic construction are combined to embody the sustainable development ideas considering the sewage treatment, ecological restoration and economic construction, and the theoretical research and the practical application are combined.

The invention discloses an application of a Hawaii bamboo in processing waste water generated in raising livestockbelonging to the field of waste water processing. The technical proposal is that the Hawaii bamboo is planted in a polluted environment with waste water generated in raising livestock. In the invention, cold resistance of the Hawaii bamboo and adsorption removal property of pollutes in the waste water are made full use of and the Hawaii bamboo is planted in such a polluted environment to absorb pollutes in the accumulated waste water to lower content of pollutes in the waste water and purify the waste water generated in raising the livestock; the application has the advantages of low operation costs, good effect and simpleness and practicability in terms of operation, thus ensuring water purification effect while developing a new plant resource for processing of the waste water generated in raising livestock, bringing about new space new progress and development for in-depth development of human-made wet land for processing waste water generated in raising livestock; the Hawaii bamboo enjoys obvious advantages compared with the existing water purifying plants in terms of operation costs, operation maintenance, processing effect or landscape value.

The present invention discloses an application of berberis julianae schneid in purification of livestock and poultry breeding biogas slurry, and belongs to the field of wastewater treatment. According to the present invention, berberis julianae schneid is planted in an environment polluted by livestock and poultry breeding biogas slurry, and absorption effects of the berberis julianae schneid on NH4<+>-N, TN, TP, CODcr and other pollutants in the livestock and poultry breeding biogas slurry, and characteristics of tenacious vitality, direct planting, no requirement of special management and perennation of the berberis julianae schneid are completely utilized so as to permanently solve the pollution problem of the livestock and poultry breeding biogas slurry. The application of the present invention has the following advantages that: the investment is low, the operation cost is low, the effect is good, the operation is simple and easy to perform, and the winter purifying effect of the artificial wetland system is ensured; the harvested berberis julianae schneid can be used for treatments of damp-heat dysentery, diarrhea, jaundice, eczema, sores ulceration, aphthae, conjunctival congestion, pharyngalgia and other syndromes; the berberis julianae schneid is adopted to treat the wastewater treatment, such that the environmental protection and the economic construction are combined, the sustainable development thoughts concurrently comprising sewage treatment, ecological restoration and economic construction are reflected, and the far-reaching significance is provided.
