Water treatment agents refer to chemicals used for water treatment. Usually referred to as chemicals used for sewage treatment. Widely used in chemical, petroleum, light industry, Daily Chemical, textile, printing and dyeing, construction, metallurgy, machinery, medicine and health, transportation, urban and rural environmental protection and other industries, the main purpose is to remove suspended solids and toxic substances in water, control the formation of scale, sludge, reduce the corrosion of water contact materials, deodorization, sterilization, decolorization, soft To stabilize water quality and desalination, so as to save water and prevent water pollution. It includes chemicals needed for cooling water and boiler water treatment, seawater desalination, membrane separation, biological treatment, flocculation and ion exchange technology. Such as corrosion inhibitors, scale inhibitors and dispersants, bactericides and algae killers, flocculants, ion exchange resins, purifiers, cleaning agents, pre-film agents and so on. The main products of water treatment agents include organic phosphorus water treatment agents, polycarboxylic acid water treatment agents, composite scale and corrosion inhibitors, bactericides and algae killers and other water treatment agents.

(II) Quality standards of irrigation water in pollution-free production bases The quality requirements of irrigation water in pollution-free production bases are basically the same as the secondary standards in the national farmland irrigation water quality standard (GB/T 18407.2-2001).
(III) Quality inspection method for irrigation water without pollution To ensure the quality of irrigation water for pollution-free fruit production, the state has made clear regulations for monitoring and testing the quality of irrigation water produced from pollution-free fruits. Irrigation water monitoring is carried out during irrigation and the sampling point should be selected at the irrigation outlet. The standard value of cyanide is the highest value measured at one time, and other standard values ​​mean the average of multiple measurements at the time of irrigation.é‡‡æ · Sampling and quantity statistics for the determination of irrigation water quality indicators shall be performed in accordance with NY/T396. The testing methods for irrigation water quality are as follows:
Determination of chloride, according to GB/T 11896 implementation;
Determination of cyanide, according to GB/T 7484 implementation;
Determination of fluoride, according to GB/T 7484 implementation;
Determination of total mercury, according to GB/T 7468 implementation;
Determination of total arsenic, according to GB/T 7484 implementation;
Determination of total cadmium, according to GB/T 7475 implementation;
Determination of total lead, according to GB/T 7475 implementation;
Determination of total copper, according to GB/T 7475 implementation;
Determination of hexavalent chromium, according to GB/T 7467 implementation;
Determination of petroleum, in accordance with GB/T 16488 implementation;
Determination of pH value, according to GB/T 6920 implementation;
The number of fecal coliforms was measured according to GB/T 7484.
Environmental conditions for pollution-free cultivation
Irrigation Water Quality Standards (I) Farmland Irrigation Water Quality Grade Standards The water used in fruit production parks must meet the national farmland irrigation water quality standard (GB5084-92). The main indicators are: pH 5.5-8.5, total mercury ≤ 0.001 mg / L, total cadmium ≤ 0.005 mg/L, total arsenic ≤ 0.1 mg/L, total lead ≤ 0.1 mg/L, chromium (hexavalent) ≤ 0.1 mg/L, chloride ≤ 250 mg/L, fluoride 3 mg /L (high fluorine area) or 2 mg/l (low fluorine area), cyanide ≤ 0.5 mg/l. The pollution index of irrigation water is divided into three levels: first grade (pollution index ≤ 0.5) is unpolluted, second grade (pollution index 0.5-1) is still clean (within the standard limit), and third grade (pollution index ≥ 1) is Pollution (beyond the alert level).
