The present invention discloses a cultivation method for Hainan huanghua pear nursery stock. The cuttage comprises the following steps of: carrying out scion cuttage from April to May, or September to November; shearing the base of the cuttage scion, at an angle of 30 DEG with a length direction of the cuttage scion, to form a bevel cut by use of a pair of sterile scissors before cuttage, and then vertically fixing the base of the cuttage scion in a container with a root promoting liquid to soak for 3-6 h; using a cuttage container cup to fill a nutrient medium to carry out cuttage, wherein a first-layer medium is formed by mixing yellow soil, biogas, and peat in a mass ratio of 1:1:1; a second-layer medium is formed by mixing red loam, coconut dust and vermicompost in a mass ratio of 3:1:2 ; and a third-layer medium is formed by mixing red loam and vermicompost in a mass ratio of 2:1; inserting the part, with a distance of 5 cm above the base of the cuttage scion, into the nutrient medium, and inserting the bevel cut into the second-layer medium. The cultivation method for Hainan huanghua pear nursery stock provided by the invention ensures a high survival rate of Hainan huanghua pear nursery stock , and the cutttage scion has strong adaptability to season.

The invention relates to a zanjon air lifting pushing solid circulation inversion A<2>O integrated construction oxidation ditch, which comprises an anoxic zone, an anaerobic zone, an aerobic zone provided with a millipore aerator group and an inversion A<2>O integrated construction oxidation ditch of a solid and liquid separating zone. The solid and liquid separating zone is arranged at the front end of a main ditch, the anaerobic zone is arranged at the tail end of the main ditch, and water inlets are respectively arranged at the front ends of the aerobic zone and the anaerobic zone. The integrated construction oxidation ditch is characterized in that a horizontal partition board which divides the main ditch into an upper groove layer and a lower groove layer is arranged at the middle-lower part of the main ditch, the aerobic zone and the anaerobic zone are respectively arranged at the upper groove layer and the lower groove layer, the aerobic zone is internally provided with n (n is more than or equal to 1) aeration lifting zone (s) which is (are) composed of an inlet water-retaining wall, an outlet water-retaining wall and the millipore aerator group and is (are) provided with a lower water inlet and an upper water outlet, the horizontal partition board of a first grade aeration lifting zone is provided with a plurality of lifting holes, and the aerobic zone is internally divided into n aerobic reaction zone (s) corresponding to the aeration lifting zone (s).The integrated construction oxidation ditch has the advantages that: the yielding water quality, particularly the dephosphorization and denitrification effect, is better, the occupation area is reduced, the equipment is reduced, the operation is simplified, and the operation cost is lowered.

The present invention belongs to the sewage treating apparatus adopting biochemical technology. The integrated stereo oxidation channel has two rectangular solid-liquid depositing separators, and the oxidation channel is separated with partition board into the upper aerobic area and the lower anaerobic area. Each of the solid-liquid depositing separators has inclined mixed liquid inlet in the bottom, overflow weir and water outlet on one side wall, and sludge reflowing port on the other wall. The two solid-liquid depositing separators are installed separately on two side walls of the stereo circulating oxidation channel. The stereo circulating oxidation channel has bottom isolated from air and this is favorable to forming anaerobic state and raising denitrifying efficiency. Compared with available oxidation channel, the present invention has 50 % reduced covered area.

The present invention relates to the field of automatic control, more particularly to a self-helping luggage consigning method, which comprises: a, printing and adhering an electronic ID, b, measuring a size; c, weighing; d, carrying out security check scanning; e, carrying out initial sorting; f, carrying out secondary sorting, and other steps. According to the present invention, the limitation due to the problems of cumbersome manual procedure, long waiting time, high labor cost and the like during the luggage consigning process is eliminated.

The present invention relates to sewage treating biological apparatus, and is especially one kind of vertically flowing composite biological sewage reducing reactor and its operation process. The vertically flowing composite biological sewage reducing reactor is separated with partition boards into three parts, including free protozoan/metazoan growth area, attached protozoan/metazoan growth arean and solid-liquid separating area. The vertically flowing composite biological sewage reducing reactor provides different protozoan/metazoan with proper habitat for stable growth, and thus has effectively raised sewage reducing effect. The present invention may be used in the reducing treatment of residual sewage from biological sewage treating system and in the treatment of reflux sewage in conventional active sewage treating system.

The invention belongs to the technical field of sewage treatment devices and in particular relates to an integrated membrane biological reaction system (MBR). The integrated membrane biological reaction system comprises an outer shell, an inner shell, a filtering system and a washing device, wherein the inner shell is arranged in the outer shell; a hollow part of the inner shell forms a first cavity; the first cavity is a membrane biochemical reaction tank; a second cavity is formed between the inner shell and the outer shell; the second cavity is a clean water tank; the filtering system is arranged on the inner shell; the inner shell is communicated with the outer shell through the filtering system; the filtering system is a stainless steel filtering screen; the washing device is arrangedin the first cavity; the washing device is used for washing the filtering system. The integrated membrane biological reaction system provided by the invention integrates a primary sedimentation tank,the biochemical reaction tank and a secondary sedimentation tank and a sewage treatment flow is simplified; the equipment has the advantages of investment saving, reliability in operation, simplicityin maintenance and low operation cost and troubles caused by membrane pollution and low pass in a traditional membrane bioreactor are completely solved; the integrated membrane biological reaction system brings a wider prospect for applying the MBR to middle-scale and small-scale sewage treatment.

The invention relates to a wastewater anaerobic biological treatment system for seasonal strain preservation and recovery, and an application thereof. The wastewater anaerobic biological treatment system comprises a water inlet device for inputting wastewater to be treated, an anaerobic biological treatment device for carrying out anaerobic biological treatment on the wastewater to be treated, a subsequent treatment device for further treating the wastewater passing through the anaerobic biological treatment device, a monitoring device for monitoring and outputting parameters of a mixed liquidin the anaerobic biological treatment device, and a control device for controlling a servo component in the anaerobic biological treatment device on the basis of a signal which is output by the monitoring device and contains a parameter value so as to adjust the corresponding parameters.
