This utility model belongs to the field of filters and discloses a self-priming fully automatic filter, including a filter body. An inlet and an outlet are respectively provided at the bottom and one side near the bottom of the filter body. A fine filter cylinder is vertically arranged in the center of the filter body, communicating with the inlet. A coarse filter assembly is horizontally arranged at the connection between the inlet and the fine filter cylinder. This self-priming fully automatic filter features a high degree of automation, can self-clean and discharge wastewater, and provides uninterrupted water supply. It has a wide range of applications, short cleaning time, and low wastewater consumption. A lead screw is used to achieve the up-and-down movement of the suction scanner, and water pressure is used to drive the automatic rotation of the rotating suction structure through a water-driven rotator. The suction device simultaneously performs up-and-down and rotational movements, covering the entire inner wall of the fine filter and scraping away and cleaning the impurities on the inner wall of the fine filter.

The invention provides a swimming pool intelligent management platform, which is characterized by comprising a partition water quality detection module for dividing a swimming pool into a plurality of detection areas, arranging a water quality sensor in each detection area, collecting water quality parameters in real time and generating water quality parameter data; the visual detection module is used for arranging an image acquisition device in the swimming pool, identifying garbage on the water surface and the bottom of the swimming pool through a visual analysis strategy based on a detection image acquired by the image acquisition device, and generating garbage detection data; the data processing and analyzing module is used for establishing a water quality state and a water quality change trend model of each detection area based on the water quality parameter data, presetting a future water quality state and analyzing a garbage distribution and generation rule based on the garbage detection data; and the intelligent management module is used for generating a comprehensive swimming pool management scheme through an intelligent control strategy according to the future water quality state and the garbage distribution condition and by acquiring the swimming pool utilization rate and the environmental parameters.

The invention relates to a method special for selective precipitation and impurity removal of phosphorus and arsenic in a sodium molybdate solution, and belongs to the technical field of impurity removal. The precipitation impurity removal method comprises the following steps: S1, adding strong acid into a pure sodium molybdate solution to carry out acid precipitation operation, adjusting the pH value of the solution to 2-3 by using the strong acid, and filtering to obtain a molybdic acid solid; s2, dissolving a molybdic acid solid and magnesium oxide in water, adding a small amount of phosphoric acid at the same time to ensure that the P concentration in the solution is 50-2000mg / l, and starting to carry out stirring reaction to obtain an impurity-removed solution; and S3, adding the impurity removal solution into the sodium molybdate solution with high P and As, uniformly stirring, then adjusting the pH value to 8-10, carrying out a precipitation reaction, filtering after the reaction to obtain filter residues and a pure sodium molybdate solution, enabling the pure sodium molybdate solution to enter a rear working section for subsequent treatment, and simultaneously taking out a part of the pure sodium molybdate solution to be used for preparing a new impurity removal solution. The method has the advantages of short impurity removal time, normal temperature and normal pressure, simple operation and easy industrialization.
