摘要： The disclosure relates to a filtration system for harvesting microalgae. The filtration system includes a filter housing with modular filtration units each containing a fungal filter. The fungal filter includes a perforated support with a capture fungus on the support. The fungal filter is adapted to be removed and replaced from the modular filtration unit, for example during operation of the filtration system. The capture fungus is adapted to capture one or more types of microalgae upon contact of the capture fungus with the microalgae, for example via fungal mycelium. During use of the filtration system to treat an influent stream containing microalgae, microalgae are captured and coated on the fungal filters. The coated fungal filters can be easily removed and the microalgae is harvested directly from the perforated support. New replacement filters can be inserted into the filtration system for continuous operation.

摘要： A phyto-mediated wastewater treatment bioreactor (PWBR) for treating wastewater effluent and agricultural effluent is disclosed herein. The PWBR is used to clean and remove emerging contaminants from water. These emerging compounds include, but are not limited to, pharmaceutical compounds, steroids and hormones, and industrial and household chemicals. Plants and/or the microorganisms adhering to the plant roots and their growing medium have the ability to take up many of these contaminants and the PWBR maximizes their treatment capability in a given space and time.

摘要： The present invention discloses a treatment process for a submerged lifting circulation type bio-membrane filter, wherein the treatment process comprises the following steps: two groups of symmetrically staggered filter curtains (2A and 2B) are adopted; the two groups of filter curtains (2A and 2B) are periodically lifted up and down in a reciprocating manner in a biofilter (1) under the action of a lifting mechanism (4), so that bio-membranes on the two groups of filter curtains (2A and 2B) are in contact with the atmosphere and sewage in turns, absorb organic matters in the sewage when lifting down for submerging, absorb oxygen when lifting up and exposing into to the atmosphere, and bring oxygen into the sewage and cause sewage turbulence in a water tank when lifting down for submerging again, so that the dissolved oxygen is uniformly distributed, thereby purifying the sewage.

摘要： Described herein are attached growth reactor systems which increase nitrifying bacteria biomass through a variety of means during warm weather. As a consequence, the attached growth reactor system contains sufficient nitrifying bacteria biomass to remove ammonia from wastewater in cold to moderate climates. In one example, there are two attached growth reactors into which wastewater is distributed discontinuously. Specifically, wastewater is transferred to the first attached growth reactor for a first period of time and then is transferred to the second attached growth reactor for a second period of time during warm weather which effectively doubles the nitrifying bacteria biomass in the system. During cold weather, approximately half of the wastewater is applied to each reactor simultaneously.

摘要： An organic industrial tailwater treatment method based on simultaneous combination of ozonation and biodegradation (SCOB), includes: placing a sponge carrier that is internally attached and grown with a biofilm in a recycle reactor; introducing air into an ozone generator to generate ozone; and introducing the ozone into the recycle reactor; where the ozone output of the recycle reactor is adjusted through a flow meter and an ozone generator adjustment knob, the sponge carrier is uniformly fluidized under the action of the ozone, and microorganisms loaded on the sponge carrier cooperate with the ozone to degrade pollutants. Easily degradable organic substances produced from the ozonation of the present disclosure can be quickly utilized by the microorganisms in the internal pores of the composite carrier, which improves the degradation and mineralization efficiency of pollutants.

摘要： A method and plant for waste disposal are provided. A recirculating arrangement recirculates leachates generated by the processes of waste treatment into the plant itself, namely into a biofilter. The leachates are treated without need for providing a dedicated arrangement for purification and disposal. In addition, the recirculated leachates introduced into the biofilter represents an additional irrigation system for the filtering material of the biofilter and contributes to maintain its humidity advantageously high. Preferably, the leachates are introduced into the biofilter at an intermediate height of the biofiltering material bed, so as to obtain a kind of “submerged irrigation” of the biofilter. More preferably, the leachates are introduced into the biofilter as homogeneously and dispersedly as possible, so as to obtain a kind of “micro-irrigation” system for the biofilter.

摘要： A water purification system for an ornamental aquarium is easily assembled as either a canister or a hang-on-back type model with a water tank or aquarium without compromising with an aesthetic appearance and low noise. The filtration element includes filtration blocks connectible in series for function and can be disassembled into a plurality of blocks that are reassembled to form the canister model and the hang-on-back model with a secure positioning feature.
