The invention discloses an automatic backwash filter device with multiple filter cartridges. The casing is divided into upper and lower chambers by a partition. Filter cartridges are installed on the partition in the form of one or more concentric circles. The casing at the lower end of the partition There is a sewage inlet on the side wall, and a clean water outlet on the side wall of the upper shell; the motor of the backwash mechanism drives the main shaft to rotate, the lifting mechanism drives the shaft to lift, and the multi-way connection seat connects the main shaft, the rotating arm and the sewage pipe Together, the main shaft drives the rotating arm to lift and rotate, the sewage pipe is fixed, the upper port of the rotating arm is fixed with a suction nozzle that can be sealed and connected to the water inlet on the partition, and the end of the sewage pipe is connected to an electric sewage valve or a pneumatic sewage valve. The control system controls the action of the motor, lifting mechanism and electric blowdown valve or pneumatic blowdown valve. The invention has the advantages of small volume, large filtering capacity, high production efficiency, good filtering effect of filtered water, good backwashing effect, low backwashing frequency, long service life of equipment, low maintenance rate and saving backwashing water.

The invention discloses a super-molecular care agent, a heating circulating water zero discharge system and a use method. The super-molecular care agent comprises the components, by weight, of 7%-10% of sodium alkyl benzene sulfonate, 10%-12% of sodium polyacrylate, 5%-6% of dodecyl dimethyl benzyl ammonium chloride, 2%-2.5% of alkanolamide, 4.5%-6% of fatty alcohol-polyoxyethylene ether, 4%-5% of cyanoacetic acid, 1%-1.5% of benzotriazole, 2%-3% of sodium tripolyphosphate, 2%-2.5% of sodium silicate, 1%-1.5% of trisodium phosphate, 2%-3% of ethylene glycol, 1%-1.5% of pyridoxine hydrochloride, 2%-2.5% of disodium hydrogen phosphate and the balance of water. The super-molecular care agent is added to heating circulating water, scaling produced by the circulating water and the system corrosion degree are reduced, and the effect of reducing sewage discharge is realized.

The invention provides an automatic anti-scale water treating device. The water treating device is communicated with a plurality of to-be-treated water bodies through a water pipe and comprises an electric wave generation device, a filtering sand cylinder, a water pump and a control system. The automatic anti-scale water treating device has the advantages that as a special electric field is designed, it is achieved that ions in the to-be-treated water bodies are in water but are not in the pipe to form flocculent bodies or crystals, and therefore the anti-scale aim is achieved; as the control system is arranged, it is achieved that treatment of the multiple to-be-treated water bodies is automatically controlled through the water treating device at the same time, the water treatment efficiency of the device is higher, and cost is lower.
