11. Wastewater
Classification
According to the chemical properties of the main pollutants contained in industrial wastewater, it is divided into: Inorganic wastewater containing mainly inorganic pollutants, organic wastewater containing mainly organic pollutants, mixed wastewater containing both organic and inorganic substances, heavy metal wastewater, wastewater containing radioactive substances and cooling water only contaminated by heat. For example, electroplating wastewater and mineral processing process wastewater are inorganic wastewater, and food or petroleum processing process wastewater is organic wastewater.
According to the products and processing objects of industrial enterprises, it can be divided into papermaking wastewater, textile wastewater, tanning wastewater, pesticide wastewater, metallurgical wastewater, oil refining wastewater, etc.
According to the main components of pollutants contained in wastewater, it can be divided into acidic wastewater, alkaline wastewater, phenol-containing wastewater, chromium-containing wastewater, organophosphorus-containing wastewater and radioactive wastewater, etc.
Recyclable garbage refers to garbage that has high recycling value and can enter waste recycling channels. Mainly including: paper (newspapers, magazines, cardboard boxes and other uncontaminated paper products, etc.), metal, glass (glass bottles and jars, flat glass and other glass products), plastic products except plastic bags, rubber and rubber Products, milk boxes and other Tetra Pak packaging, beverage bottles, etc.
Non-recyclable garbage includes kitchen garbage, hazardous garbage and other garbage. However, since kitchen garbage should not be placed in road bins, the non-recyclable garbage in the bins is hazardous waste and other garbage.
Hazardous waste refers to waste containing toxic and harmful chemicals, such as: batteries, used lamps and bulbs, expired medicines, expired daily cosmetics, hair dyes, pesticide containers, herbicide containers , discarded mercury thermometers, discarded small household appliances, discarded printer ink cartridges, toner cartridges, etc.
Other garbage is a general term for all garbage except recyclable garbage, hazardous garbage, and kitchen garbage, including: contaminated and non-renewable paper, contaminated or other non-recyclable glass, and plastic bags and other contaminated plastic products, used clothing and other textiles, worn ceramics, shells, cigarette butts, dust, etc.

Scrap specifications
Scrap can be divided into repairable or non-repairable according to the degree to which it does not meet the original specifications or technical standards. Scrap. Repairable waste means that the waste can be used after being repaired.
And the cost of repair is economically unreasonable; irreparable waste means that the waste cannot be repaired, or the cost of repair is not economically cost-effective.
Scrap losses include scrap losses after the cost of irreparable scraps minus the recyclable residual value of the scraps, and the repair costs of repairable scraps.
All losses incurred on scrap products discovered after the sale, including the transportation and miscellaneous fees paid when returning the scrap products, should be treated as administrative expenses and are not included in the loss of scrap products.
The loss of repairable scrap products is generally the same as the cost of qualified products. First, the "waste loss" account is debited and the relevant accounts are credited according to the allocation table of material costs, salary expenses, auxiliary production expenses, manufacturing expenses, etc. .
Accounting
In order to calculate the scrap losses that occur during the production process, you can set up the "Scrap Loss" detailed account under the "Basic Production" account to organize accounting. The debit side records the production costs of irreparable scrap and the repair costs of repairable scrap.
The creditor registers the value of the recycled scrap that should be deducted from the cost of the scrap. The difference between the above-mentioned contents of the debit and creditors of this account is the total net loss of waste products of the enterprise.
The corresponding part borne by the faulty party will be transferred from its credit to the debit of the "other receivables" account, and compensation will be required in a timely manner; the rest of the net loss of waste products should all be attributed to the same type completed in the current period. The product cost burden is included in the "waste loss" item.
That is, the credit of the "Basic Production - Scrap Loss" account is transferred to the debit of the "Basic Production - ×× Products" account. After the transfer, the "Basic Production - Scrap Loss" account should have no ending balance. .
