The invention relates to a purification method and equipment for cool circulating water or town secondary sewage water, and is characterized in that the invention has the following steps: a quick mixing zone 1 for mixing a ready treated liquid and a mixing medicament, a flocculating reaction zone 2 for mixing and flocculating a mixed liquid with a backflow deposit substance to get a compact alum at an outlet of the zone, a depositing and concentrating zone 3 for separating a supernatant liquor and a suspension solid and for returning and draining a deposit substance, and a filtering facility zone 4 for purifying the supernatant liquor; the equipment of the invention mainly comprises the quick mixing zone, a high efficient clarification tank and a filtering zone; the invention designs the purification method and equipment for liquid and water; the water quality from the invention is stable, the cost is lower, which changes the prior purification method for liquid and water.

An internal liquid cooling circulation system of an air filter, comprising a box body and an air outlet pipe, the air outlet pipes are fixedly connected to the lower left and right sides of the box body, and a fixing device is installed on the upper left side of the box body. The internal liquid cooling circulation system of the air filter, through the mutual cooperation between the first water tank, the second water tank, the first water pipe, the vertical bar and the second horizontal plate, can carry out water injection work outside the device, so that The operation is simpler and more convenient. Through the mutual cooperation between the first water tank, water pump, second water pipe, arc water pipe, vertical plate and fan, the water circulation time in the arc water pipe can be lengthened, thereby improving the cooling effect and practical. The performance is better, through the mutual cooperation between the L-shaped plate, the fourth horizontal plate, the activated carbon layer, the particle filter, the organic filter and the negative ion generator, the air can be better filtered and the filtering effect is improved.

The invention discloses a centralized intelligent control system of air purifiers. The centralized intelligent control system comprises the multiple air purifiers, control hardware, first detection modules, a second detection module, an intelligent phone module, a data processing module and a transmission module. The control hardware controls starting and stopping, the purification degrees and the air volumes of the air purifiers according to commands and further comprises third signal switching devices and distance meters. The data processing module provides an optimal control scheme of the air purifiers. The purification effect required by a user is achieved with the minimum power consumption. According to the centralized intelligent control system, an intelligent phone is utilized for carrying out centralized control over the multiple air purifiers; in an automatic control centralized purification mode, according to user needs, intelligent centralized purification is carried out on a designated area; the purification effect required by the user is achieved with the minimum power consumption through the optimal control scheme; and a large amount of energy can be saved, and the purification effect and purification speed of air of the designated area can be effectively increased.

The present inventions relates to an apparatus for purifying wastewater and a method thereof, which comprises: a stirring part to make bubbles impregnated into floc through high speed stirring by adding floc forming materials to influent and stirring them; an air supply part to supply air to the stirring part to make more bubbles impregnated; a pumping part to conduct pressurized conveying of the floc included treatment water; a cyclone part to separate high density floc to downstream and treatment water with low density floc to upstream from the pressurized treatment water; and a flotation part to separate floc from the treatment water with floc supplied from the cyclone part. Therefore, the present invention have an effect that it is possible to improve purification speed of wastewater and obtain good quality of purified water.

The invention discloses a method for treating ammonia nitrogen in acid wastewater containing heavy metals, and belongs to the technical field of water treatment. The method comprises the following steps of: 1, after carrying out grinding and high-temperature plasticizing processing on zeolite and blast furnace steel slags, performing a hydrothermal reaction with water, carrying out sedimentation, filtration, drying and grinding on a reaction product, feeding the obtained product into the wastewater, and removing the heavy metals; 2, adding a cationic polymer into the wastewater to form a flocculation organism, removing toxic cyanide by an air jet cyclone floating device and a skimmer, and separating the flocculation organism; 3, leading the wastewater into a nitrification region to carry out nitrification; 4, after carrying out deoxidation on the wastewater, enabling the wastewater to enter an anaerobic denitrification to carry out denitrification; 5, filtering the wastewater by a submerged membrane to obtain filtered and purified water. According to the method disclosed by the invention, the heavy metals, the organism, the toxic cyanide and the ammonia nitrogen all can be effectively removed, and a sewage purification speed and biological purification intensity are improved; moreover, the method disclosed by the invention is low in construction investment, low in operation cost and suitable to popularize and apply.
