XI。 waste water

classify

According to the chemical properties of the main pollutants contained in industrial wastewater, it can be divided into: inorganic wastewater mainly containing inorganic pollutants, organic wastewater mainly containing organic pollutants, mixed wastewater containing both organic and inorganic substances, heavy metal wastewater, wastewater containing radioactive substances and cooling water polluted only by heat. For example, electroplating wastewater and mineral processing wastewater belong to inorganic wastewater, while food or petroleum processing wastewater belongs to organic wastewater.

According to the products and treatment objects of industrial enterprises, it can be divided into papermaking wastewater, textile wastewater, tannery wastewater, pesticide wastewater, metallurgical wastewater, oil refining wastewater and so on.

According to the main components of pollutants contained in wastewater, it can be divided into acidic wastewater, alkaline wastewater, phenolic wastewater, chromium-containing wastewater, organophosphorus wastewater and radioactive wastewater.

Recyclable garbage refers to garbage with high recycling value that can enter the waste recycling channel. It mainly includes: unpolluted paper products such as newspapers, magazines and cartons. ), metal, glass (glass products such as glass bottles and flat glass), plastic products except plastic bags, rubber and rubber products, and tetra pak packaging such as milk boxes and beverage bottles.

Non-recyclable garbage includes kitchen waste, hazardous waste and other garbage. However, the kitchen waste should not be put into the road shell box, and the unrecoverable garbage in the shell box is harmful waste and other garbage.

Among them, hazardous waste refers to garbage containing toxic and harmful chemicals, such as batteries, waste light bulbs, expired drugs, expired daily cosmetics, hair dyes, pesticide containers, herbicide containers, waste water silver thermometers, waste small household appliances, waste printer cartridges, toner cartridges, etc.

Other garbage refers to all garbage except recyclable garbage, hazardous waste and kitchen garbage, including: polluted and non-renewable paper, polluted or other non-recyclable plastic products such as glass and plastic bags, textiles such as waste clothes, waste ceramics, shells, cigarette butts and dust.

Extended data:

Waste specification

Waste products can be divided into repairable waste products and unrepairable waste products according to the degree that they do not meet the original specifications or technical standards. Repairable waste refers to the waste that can be used after repair.

In addition, the repair cost is economical; Irreparable waste refers to waste that cannot be repaired, or the cost of repair is uneconomical.

Waste loss includes the cost of unrepairable waste minus the recoverable residual value of waste, and the repair cost of repairable waste.

Waste losses found after sale, including transportation fees and miscellaneous fees paid when returning waste, should be treated as management expenses and not included in waste losses.

Generally speaking, the loss of repairable waste products is the same as the cost of qualified products. A, according to the material cost, wage cost, auxiliary production cost, manufacturing cost distribution table, debit "waste loss" subjects, credited to the relevant subjects.

economic/business accounting

In order to account for the waste loss in the production process, you can set up the detailed account organization accounting of waste loss under the basic production account. Debit registers the production cost of unrepairable waste and the repair cost of repairable waste.

The lender registers the value of the recovered waste that should be deducted from the waste cost. The difference between the debits offset by the above contents and the debits of this account is the net loss of all waste products of the enterprise.

Among them, the part corresponding to the burden of the negligent person will be transferred from its lender to the debit of the "other receivables" account in order to claim for compensation in time; The net loss of other waste products should be borne by the cost of similar products completed in this period and included in the "waste loss" project.

That is, from the credit of the subject of "loss of basic production and waste products" to the debit of the subject of "loss of basic production and waste products", there should be no ending balance in the subject of "loss of basic production and waste products" after carrying forward.
