Abstract

The invention provides a scale inhibitor as well as a preparation method and an application thereof. A scale inhibition mechanism is based on chelation solubilization, dispersion, electrostatic repulsion and lattice distortion. Several medicament monomers are selected in a formula to be compounded and used, and the scale inhibition capability of the scale inhibitor is far higher than that of the medicament monomers by means of synergistic effect between the monomers; calcium carbonate scale and magnesium carbonate scale can be effectively prevented from being produced, wherein the inhibition rate of calcium carbonate scale is 89.3%-92.6%, the inhibition rate of magnesium carbonate scale is 92.1%-96.2%, organic scale can be effectively prevented from adhering to the pipe wall, so that the pipe wall is smooth, and circulation flux of a leachate is ensured; the pipe cleaning frequency of an existing anaerobic system can be reduced to once a year from once every two months; equipment suchas an anaerobic circulating pump, a denitrification water inlet pump and the like in contact with the leachate in a biochemical section in an anaerobic system can be protected, blockage of the equipment is prevented, and the service life of the equipment is prolonged; pipe bursting and other accidents caused by pipe fouling and blocking can be effectively prevented, and production can be performedcontinuously and stably.

Description

technical field [0001] The invention relates to the field of leachate treatment, in particular to a scale inhibitor and its preparation method and application. Background technique [0002] At present, waste incineration power plants generally adopt the process of "pretreatment + anaerobic treatment + secondary AO + membrane advanced treatment" to treat landfill leachate. Among them, anaerobic system is the main method to remove COD in leachate. [0003] Landfill leachate mainly comes from the liquid produced by the waste itself holding water and decomposing the waste. The water quality of the leachate is complex, the water quality and quantity fluctuate greatly, and the concentration of pollutants is high. According to the current statistics of incineration plant leachate water quality data, the concentration of COD is 30000-60000mg / L, the concentration of BOD is 20000-40000mg / L, the concentration of ammonia nitrogen is 1500-2500mg / L, and the hardness is 1500-5000mg / L (ca...
