The invention relates to the technical field of water purifiers, and in particular relates to a micro-wastewater purifier. The micro-wastewater purifier comprises a prefilter, a water inlet electromagnetic valve, a water pump, a filter element mechanism and an RO film which are connected through a pipeline, and further comprises a finite flow and circulating electromagnetic valve, a flow-limiting valve, a one-way valve, a high-pressure switch, a water storage bucket and a post-filter, wherein the prefilter is connected with a raw water pipeline; a purified water outlet of the RO film is connected with a purified water outlet pipe; the one-way valve and the high-pressure switch are sequentially arranged on the purified water outlet pipe along the water flow direction; the water outlet end of the purified water outlet pipe is respectively connected with the water storage bucket and the post-filter; a concentrated water outlet of the RO film is connected with a concentrated water outlet pipe; the water outlet end of the concentrated water outlet pipe is respectively connected with a water return pipe and a drain pipe; the finite flow and circulating electromagnetic valve is arranged on the water return pipe; the water outlet end of the water return pipe is connected with the water inlet end of the water pump; and a flow-limiting valve is arranged on the drain pipe. According to the micro-wastewater purifier, water resources can be saved; the amount of discharged wastewater is small; and the service life of the RO film and the water quality of the purified water are ensured.

The invention discloses a method for using a water-saving ultra-pure water machine. The pure water flushing pipe is connected to the water inlet pipe through the water inlet pipe tee, the concentrated water return pipe is connected to the concentrated water inlet pipe tee through the concentrated water inlet pipe tee, and the concentrated water inlet pipe tee is connected to the water inlet pipe. The water pipes are connected, so that both concentrated water and purified water can flow back and re-enter the primary filter element group, reducing the TDS value of raw water and restoring the TDS value of raw water, which can effectively save water; when pure water with higher purity is needed, use concentrated water first After a few minutes, turn on the pure water outlet switch, so that the pure water quality will be more pure and fresh. Pure water control four-way valve and concentrated water control four-way valve can ensure timely shutdown. Therefore, the present invention can make the pure water quality more pure and fresh, effectively prolong the service life of the RO membrane, effectively save water, and is convenient and flexible to use.

The invention relates to composite biochemical, coupled physicochemical, and heavy-metal-removing sewage treatment process and technology. The invention mainly discloses a continuous operation system composed of a mechanical solid-liquid separation unit, a composite biochemical treatment unit, a coupling physicochemical treatment unit, and a waste comprehensive utilization unit. According to the invention, a plant capillary biofilm bed technology, a shrub-type plant heavy metal removing technology, a flocculation complexation reaction technology, an inorganic membrane filtration technology, and optical, electrical, and membrane coupled desalination technology are adopted, such that harmful substances and heavy metal elements in sewage can be effectively removed. Treated water reaches a discharge standard, and can be recycled. Also, according to the invention, with microbial fermentation technology and high-temperature cracking technology, waste, sludge, and shrub-type plant fuel-wood are converted into nutritive soil, active carbon, tar and electrical power, such that waste is turned valuable, and pollutant discharge reduction or zero discharge is realized. The process and technology provided by the invention can be applied in organic sewage and industrial sewage treatment, and especially provides a good treatment effect against garbage leachate.

The present invention relates to the technical field of water purification equipment, in particular to a control method, a control device, water purification equipment and a storage medium of water purification equipment. The control method of the water purification equipment includes the following steps: judging whether the water purification equipment enters the standby state; when the water purification equipment enters the standby state, the pure water return branch is turned on, and the opening of the waste water valve is set to the first opening; wherein , the water purification equipment includes a reverse osmosis filter element, a waste water valve is arranged on the waste water branch road of the reverse osmosis filter element, a pure water return branch is arranged between the water outlet end and the water inlet end of the reverse osmosis filter element, and the first opening is smaller than the second The second opening is the opening of the waste water valve when the water purification equipment normally outputs pure water. The opening of the waste water valve in the technical solution of the present invention is smaller than that of the waste water valve when the pure water is normally discharged from the pure water backflow flushing state, which reduces the concentrated water discharge during backflow and saves water resources.
